Features of light catching

In December 2017, I acquired a fairly powerful LED light from the Convoy L6 and took it on a trip to Vietnam. I was satisfied with the results of fishing with him. If the forum did not have information on the fly on this device, then I will tell you in more detail. I haven't tried it out in the European band yet.

Locman, I wonder what kind of LEDs are there in the lantern? Is ultraviolet light present in their spectrum?

I can't say anything about ultraviolet light, the lamp shines with a neutral white light. In turbo mode, when you hover over moths, especially large ones, they fall to the ground. Clearly knocks down hawkmoth. Break out from the beam percents10 and then if the distance to them is more than 30 meters. Sat on the ground or went to the lantern well all kinds of bears, etc. But there were some species that draped from the beam. The diode costs XHP-70 with a power of more than 30 watts, a luminous flux of 3800 lm. In turbo mode, i.e. at the 4th speed, it works for about an hour, the light is slightly brighter than the car shines in the high beam. On the third (also very bright 1200lm) will work for more than 2 hours. There are 2 28850 batteries in series with a capacity of 4500mA. I will repeat what I experienced in the tropics when driving on a forest road and field. I think we need to check with the screen. By the way, I arrived in Phok Quoc Vietnam today.

For information. Got the following:

It matches the description, but you can't try it in the fields yet.

mikee purchase purpose?

For such an amount, you can buy a generator, with wires, lamps, a screen, a cart that would carry it all and still have enough gas left.

Good stuff!
Googled - like these batteries can be checked in the luggage?

You can't always take a generator to a distant country...

This is for light traps, I take it? So generators and carts do not roll here)))

You can buy a generator in a distant country on the spot and leave it there.

Chinese ampere / hours can be safely divided by 10

In addition, not every airline will allow you to carry accumulators in your luggage. So this roulette is still the same!

You rich people have your own quirks

Mikhail wrote something that matches the description - I think he checked it out.
Yes, and the weight of the LiPo battery in 6 kg somehow hints that the amperes with the clock there are close to real ones.

in any case we are waiting for the results of the load test

The generator costs about 100 bucks, if four people go on an expedition, this is a little more than a thousand rubles for each. And these accumulators cost like two genes, and they will give light in any way less than a pair of drv of 160 watts. So, it's not the rich here, but an elementary calculation.

Chinese ampere / hours can be safely divided into 10

Actually, people write correctly, what kind of batteries are these, it says that with a capacity of 60Ah and a voltage of 12V, the weight is 2.3 kg, which means that it has an energy density of about 300 w / h/kg! See how much the LiPo bike accumulator weighs for similar parameters - at least 7 kg )))

Already how many powerbanks of the 5V 50Ah type were there, inside which there are two 2500mah batteries, well, now this has appeared, but what, people take

Twice I took a trip to Thailand.Phuket and Vietnam Nha Trang Patriot inverter generator power 900 watts weight about 9kg. When departing from Moscow, they didn't even ask questions when taking an X-ray at the airport. From Phuket, too, and the Vietnamese slowed down, allegedly there may be gasoline residues. They told me to buy a styrofoam box for 50 bucks, in which I should additionally pack the device. We agreed on the fact that 30 green-but on the paw. The generator drove dry without oil and gasoline, of course, even with the swap button dried up the remains. But I note that the years on the AWL 250 even stab was poor, far from expected. But here you need to analyze the conditions.

mikee purchase purpose?

I'm starting to answer. Goals:
1. night fishing for autonomous traps;
2. lighting the camp;
3. reserve in case the battery dies in the car in the ass of the world (we know, swam).

For such an amount, you can buy a generator, with wires, lamps, a screen, a cart that would carry it all and still have enough gas left.

1. Do you feel the difference between the weight of these two batteries? Unfortunately, after the knee replacement, it is still difficult to carry 16 kG on the sands/swamps/forests.
2. The difference in price is 2 times for a horseradish lead DRUM and no posti - for a good one. The Chinese one cost 11,500 Russian rubles.
3. Li-Po, unlike Pb-Acid, is not subject to self-discharge, and the service life is longer.
4. The Chinese is equipped with a charge indicator and a USB port, i.e. it is more convenient to operate.

Good stuff!
Googled - like these batteries can be checked in the luggage?

Unfortunately, this should be checked experimentally. After problems with self-igniting smartphone batteries, many airlines banned
their transportation in luggage. Last year in Almaty, they tried to find out about powerbank in my hand luggage, but they missed it.

To do this, as it turned out, by 1.5-2. See the answers below.

You can buy a generator in a distant country on the spot and leave it there.

This is usually what we do, but:
- in order to buy something there (abroad or in our outback), you need to spend at least a day searching for it;
- purchased two-stroke generators of Chinese production failed repeatedly. Often the trip turns into a daily hemorrhoid with repairs/adjustments. You catch them at night and treat them during the day. Yes, and the inductive load of the throttle is not well tolerated, and PRA sometimes kills : - (

in any case, we are waiting for the results of the load tests

I finally tried it. The experiment, however, is preliminary and not complete.
So, the installation consists of:
- the aforementioned Chinese battery;
- Chinese converter 12DC / 220AC with a power of 100W. It sticks into the car's cigarette lighter, the efficiency is unknown, and it includes a fan.
- PRA 220V/70V to the lamp, efficiency unknown;
- 22W UV Sylvania lamp.

Stages:
- the battery arrived with a charge (according to its own indicator) - 85%. Charged up to 100%. Immediately after disconnecting the standard charger, the displayed charge level dropped to 96% on the screen. It should be noted that there are no methods for directly measuring the capacity of batteries and, accordingly, devices. Therefore, I do not know what is measured and recalculated there and how indirectly;
- after 6 hours of continuous operation, the charge level is 66%;
- the unit is turned off until morning. When turned on, the charge level is 70%. It looks like self-healing (it happens with lithium batteries).
- after 2.5 hours of operation, the charge level is 55%;
- another forced break for a couple of hours, switching on, the charge level is 59%;
- measurement of the voltage at the battery terminals with a voltmeter (I didn't measure it before) - 11.8 V;
- 3.5 hours of operation, the charge is 34%, the voltage is 10.4 V.
-the experiment is forcibly completed (he left the village) with the lamp still burning. It also lit up after switching off.

Total: 12 hours of intermittent operation with the battery indicator turned on (also consumes).

Comments:
- the 12/220 converter from the lead battery refused to work already at a voltage of 11V;
- I estimate the overall efficiency of the entire conversion chain to be no higher than 0.7;
- the same scheme withstood about 20 hours when working from the lead battery;
- I do not exclude that in relation to the built-in USB port, the battery capacity will be closer to the stated 60%, because there is less restriction on the input voltage of the converter.

I will continue my experiments :-)

Improvement for the Entosphinx screen.
The ends of arcs often fall out of holes during assembly or in strong winds.

Elastic band, carabiner, screw, nut with lamb-voila. The height of the carabiner can be adjusted by releasing the nut.

Please tell me who knows if there are 12v UV lamps? Attempts to climb on the Internet did not give any results. Thank you in advance!

Oleg, hello!
I think you won't be able to find such lamps. I've been using inexpensive devices for five years now, and I'm quite happy with it. Not DRL of course, but for those who do not have the opportunity to use the generator, I think the ideal option.
1) Feron FLU10 T8 G13 18W dual-socket fluorescent lamp with black bulb https://shop.feron.ru/catalog/ultrafioletov...chernoy_kolboy/
2) Yellow HR 12-12 battery for UPS http://www.all-generators.ru/products/akb/...ellow-hr-12-12/
3) Automotive inverter AIRLINE API-150-01 http://www.220-volt.ru/catalog-142220/
Middle plus side ears on the minus side. The price is only 3,000 rubles. The weight is less than 4 kg., a new battery without additional white illumination lasts for at least 8 hours.

Correction, the new battery bought the day before yesterday worked not 8 hours but almost 11.

I used such batteries, unfortunately, through the season, God forbid it lasts for an hour and a half, i.e. every season you need to buy a new one. Yes and after 10-15 nights of use is not enough for 8 hours

The same container with the same lamp? It sounds, I'm sorry, like a fairy tale. Nominally, a 12V battery at 12 Ah will produce 144W of power, and this is provided nominally 100% discharge and removal of sufficient voltage to operate the inverter until the end of the process, and the 18W LL lamp will nominally consume the same 144W in 8h without taking into account losses on the PRA. In reality, a well-charged battery with a long discharge of low current and constant load initially produces slightly more than the nominal value, but there are losses on the inverter and wiring (usually at least 8-10%), and to remove the maximum discharge from it, you need a low-power inverter without a current cut-off, and its efficiency is even lower, although lower and no-load current. Lamp consumption depends on the PRA in the lamp, with EmPRA it will consume 10-30% more than the nominal value, and with EPRA it is conditionally nominal or in some cases 5-7% less than the nominal value (for example, 2x36W with a high-quality and well-chosen EPRA will consume not 72W per hour, but 68, measured), but all this seems insufficient, to turn 8h into 11h (+37%). What's the secret?

This is strange, because AGM batteries of normal quality (Yellow did not use, but for Delta this is so) are designed for cyclic operation for at least 200 cycles at full (nominally 100%) discharge, or at least 400 cycles at 50% discharge, and if it is discharged no more, more than 30%, then more than 600 cycles. This is provided that the operating and storage temperature is 5-30C, the battery is not stored discharged for a long time and is charged for a new cycle for a sufficient time with a weak current to the nominal value (it is advisable to use a special charger from the mains, car or solar battery with a current limiter). Under these conditions, it lasts for 5-7 years, even with fairly intensive use (about 30-50 nights per season). From the point of view of battery life, as well as the maximum power of the lamp used, it is better to use the most capacious battery, discharging it minimally. I often use it on trips where for one reason or another it is impossible to take a generator (or it is undesirable to use it), car battery + inverter 200-300W + CFL lamp UV blacklight 26W (Camelion or equivalent). This lamp consumes in reality less than the nominal value due to the effective built-in PRA, while giving more linear light (since it is T4), and does not require a lamp (only a cartridge). Usually, according to my interests, it is enough for me to shine up to 4-5h per evening, respectively, it will consume up to 125 watts. The smallest car battery of 12V 40ah will nominally produce 480W, i.e. it will discharge less than 30% when 125W is issued, and it will still be able to start the engine. But, of course, without a car on itself, it is already uncomfortable to drag it (13kg). But if you use a similar 9W lamp, the AGM 12-12 battery is enough for the same discharge parameters, and it weighs only 3.5 kg. In addition, it is really possible to charge it with a solar battery with a nominal value of 9 W for the next day (you need 5-10 hours of sunny weather). A well - known example of a ready-made device that combines a battery, a charging device, a 220V inverter, 12V and USB outputs, protection and everything you need is the Goal Zero Yeti 150 with a Nomad13 solar battery. You can build it yourself and much cheaper, and even with a better battery, but not so convenient. Unfortunately, carrying it on planes is now problematic. I was looking for a similar device, in which instead of one AGM or even a lithium battery, there is a battery of many 18650 accumulators, it could be carried everywhere, and it is still convenient for many, but I did not find it. It seems to me that in autonomous conditions, when everything is "on its own", it is important not to use too much load, even at the expense of the range of attraction, otherwise it is difficult to ensure full reloading and a long service life. In the kit given in previous posts, I would replace the LL T8 18W lamp + a lamp from PRA to CFL 9W 220V + cartridge.

Dear Barnaba, good day! Alas, I'm in the electrical kettle kettle so all painted by you for me a dark forest. I used to use a B. P. BATTERY 12/12. It worked for 8 hours and last weekend I bought a new Yellow to replace it. I charged it and as always put it to check at home, the result is 10 hours and 40 minutes. An inverter for 150, a lamp as I already wrote, well, and a wire about three meters long. Apparently, a lot depends on the brand of the battery, too, if one new one dies after 8 and the other 11 hours. My former one, for example, which is already 5 years old, now lasts for three and a half hours and sometimes for 4, what is the reason for the difference in 30 minutes I do not understand, I always charge the same. Once, for the sake of experiment, I connected an 80-watt DRL beater through a 300-watt inverter, the result is 20 minutes of operation.

By the way, is there a significant difference between these two lamps? I have never tried it on a turntable, but one friend did not recommend it to me.

Both lamps are linear fluorescent, but the first is a regular T8, and the second is a compact T4. They are similar in spectrum, they shine in UV with a peak at 365nm, all light is shorter than 300nm and longer than 400nm (i.e., almost all visible light). it is cut off by Wood glass, from which the body is made. The first requires a lamp with a PRA and G13 cartridges, and the second requires only a regular E27 socket for 220V, the PRA is built into the base. The first one is nominally 18W, but depending on the PRA, it can actually consume either a little less or noticeably more. The second one consumes approximately 25W (nominal 26W) with standard network parameters. The second lamp has a thinner tube T4, it gives a greater light output per unit length than T8. Partly because of this, but primarily because of the power difference, the luminous flux of the second lamp is one and a half times larger-560lm versus 365lm. Accordingly, the range of attraction is noticeably longer. It attracts you very well, I don't know why it wasn't recommended to you. In addition, it is more convenient for a number of screens, and together with the lamp (cartridge) it is more compact in transportation and weighs less, and is also less likely to be damaged, especially in its own rigid box. But it will land the battery earlier than the less powerful one. Under the generator, I often use it in conjunction with regular DRL/DRV, this gives an additional effect, especially for twilight views, although its light is many times weaker than the main one.

Thank you very much, I will definitely try to try them combined in the near future. I noticed that the second 26 W acts more harshly on the eyes, there is discomfort, a slight cut, sand.

Ordinary linear fluorescent lamp Blacklight. It is attractive, but it is also weak at a short distance due to low power. Compacts with 26W are preferable, and they do not need a lamp with PRA. Even better to use in addition to DRL.

By the way, is there a significant difference between these two lamps? I have never tried it on a turntable, but one friend did not recommend it to me.

I recently purchased such a lamp under the 26W E27 socket. I use it together with an 11W LED. I'm happy with the result!

Hi all, I wanted to ask who used lamps for plants as a light trap source, if there are any, what is the result, and what is the spectrum in these lamps(it shines in an incomprehensible pink-lilac color), they are not cheap khttps: / / yandex.fr/images/search?techt=100%...0604 & source=schiz
