Features of light catching

From my experience this year of fishing on 8 W SYLVANIA Blacklight 368 F8W / T5 / BL368 flies many times worse than on the same drv 125, and on the drv 250 it flies even better (drl did not try). On the drv at home I catch, and I took a fluorescent one for rare trips to the forests and fields, so that it works from 12 volts. I really didn't like it, I'm thinking about an inverter for 220 or a generator... No, well, of course something is flying, not to say that nothing at all.

Friends of the good hour! In the field, I have been using the device shown in the photo for the third year now, maybe someone will be interested. Alas DRL from my battery is lit for only 20 minutes then the inverter starts beeping notifying about the power discharge. DRV from it did not try but it can work longer? My device is enough to work from 22 to 4-5 hours a day. The other day, the lamp was covered and yesterday I replaced it with a UV luminescent lamp at 26 watts. Camelion Blacklight Blue which in the off state is not black but dark purple. I tried it on the balcony like fly, given the multiple lighting in the courtyards. In general, has anyone tried DRV from a 12-volt battery via an inverter? Interesting opening hours.

Does anyone know the difference between black and white UV lamps for our purposes? (They look like the tubes in the pictures above, with one white tube and the other black tube when turned off.)

The question is removed.

If someone does not know that mercury lamps should be operated vertically or at an angle of no more than 30 degrees-be aware :-- ) This case was never obvious to me, for example...

Well, turn it on, tilt it, it will go out, you will understand that something is wrong. And you can also pay attention to what is written on the packaging. DRL shines in any position, but DRV-strictly vertical, i.e. strictly up or down with the base, otherwise it goes out

It's written for the Phillips, but not for all Osrams and General Electricians. When my face started blinking, it didn't occur to me that it was coming from around the corner. The impression was that the contact was bad.
In general, I wrote info, maybe someone will need it.

Battery capacity / load current = operating time.

Battery capacity / load current = operating time.

A 250 W lamp, for example, means it eats 250/220 = approximately 1.15 Amps
of battery at 50 Ah, divided by the lamp current. 50/1, 15 = approximately 43.5
Well, and corrections.
If there is an inverter, conversion to alternating current usually goes with an efficiency of about 80%.
Plus, the battery almost never gets a full charge/discharges during storage - also 80% of the maximum
43.5*0.8=34.8
and again
34.8*0.8=27.84 hours per 250W DRL lamp

Something like that.
You need to monitor the discharge so that the voltage does not fall below 10.5-11V, otherwise the battery can be almost immediately scrapped.
And discharge with a current of no more than 0.1 S - in this case, 5A. This will further affect the opening time...

A 250 W lamp, for example, means it eats 250/220 = approximately 1.15 Amps
of battery at 50 Ah, divided by the lamp current. 50/1. 15 = approximately 43.5

This is what you calculated for a 220 Volt battery pack. And in your case, the load current is the current consumed by the 12/220 inverter loaded with the lamp. This current is much larger. If you do not take into account the loss of the inverter, it will be 250/12, i.e. about 21 amps. With an efficiency of 80%, it will be about 25 Amps.

and the truth. I need to go to bed earlier
then I was surprised that one DRLku can feed a day...
but such a lead current for a couple of charge-discharge cycles)

Hello! Need information about what approximately the range of UV radiation gives a split DRL. And in general, tell me a lamp in the range of 310-390 nm if the drl does not fit.

About DRL found that 152 nm somewhere. And in the range of 310-390 nm, what is there?

if the drl is not suitable.

Why doesn't it fit?

You need a range of 310-390 nm approximately.

You need a range of 310-390 nm approximately.

Mercury vapor emits the following spectral lines used in gas-discharge lamps of the DRL type:
185, 254, 365, 405, 436, 546, 572 nm. The first three are the most intense. So that DRLki fit the desired range.
Yes, do not forget to split the outer flask with phosphor

With regard to low-power lamps and a bias in the UV part of the spectrum.
It flies very well on them, even during the supermoon I received 4-5 mattresses of material. BUT - they are useless to use on the screen. The screen reflects UV, your butterflies land in the distance (this is enough for them), only micra flies close to the UV tube. Low-power lamps are most logical to use in light traps - the catch is very good. I used this summer for the first time svetolovushki, from the screen eventually otkzalsya-not the same efficiency. Especially if you use traps with both black and white ultraviolet light - even things you've never seen are caught.

Can I learn more about the reflection/non-reflection of UV from the screen and the dependence of this on the lamp power? (I am in no way trying to challenge your experience, just the logic of this conclusion turned out to be too much for me.) In the case of powerful (stab DRL) use of the screen-is it logical?

I honestly couldn't stomach the question.
pricked drl never used-my vision is more expensive than any butterflies.

screen usage is always logical!

I shouldn't have given up the screen! You're missing a lot of material. It flies well in UV traps, I don't dispute that. and even what doesn't fly to the screen sometimes. but! In my experience, there are almost always a lot more butterflies coming to the screen than to the traps, both in terms of number and species composition. I've been using light traps for two seasons now. I tried different combinations of combinations with the screen. conclusion-it is optimal to catch + 1-2 light traps on the screen. then the coverage of the fauna is maximal.

Depends on what the traps are...

after such a statement - a photo of your trap in the studio!

In Lepstore there were UV lights with built-in accumulators. For MOLBIOL users — at a reduced price with a review condition. See this topic for more details: http://molbiol.ru/forums/index.php?showtop...dpost&p=1502460

The idea just hit me in one place
I have long been in the "bins of the Motherland" 3 such lamps from the minibus" Bull " early release:

They have these lamps in them:

Battery available: http://www.delta-batt.com/upload/iblock/cf..._hr_12-34_w.pdf

N. B. if there is not enough capacity then you can take this one: http://www.delta-batt.com/upload/iblock/bb...0hr%2012-12.pdf
The scheme is compiled on this database:

And all 3 lamps in it consume a relatively small current:

In my opinion, the idea has a right to exist? Tomorrow I will try in a compartment with a UV lamp, which is mentioned in the post above if the weather allows.
P. S. I forgot to add The lamps already have a built-in converter to power these lamps (opened in the center) and the construction assembly weighs with this acc. about 3 kg.

In my opinion, the idea has a right to exist?

And what exactly is the idea? A typical scheme is: battery-starting and regulating device-lamp.

The idea, of course, has the right to exist (and who could forbid it? ), but, imho, this does not make much sense, if only placed in a very open and elevated place and without light interference around. To illuminate the screen (ease of operation, attracting poorly flying or non-flying insects from the immediate vicinity), 3 12W lamps are superfluous, one 0.5-1W LED on batteries, or from a battery of the same size and weight, would be enough - it could work for at least several nights. The same system will work, imho, no more than an hour or two. The increase in the range of the light trap (let's call the screen+lamp system) in comparison with UV 8W will not happen much, it is better to take 1 noticeably more powerful lamp (say, CFL 26W), this makes sense. Attraction in this case goes in stages-first to normal light, and in the range of UV increases and is directed to the screen, so that such a spark (for example, 9W UV + 26W) can compete with street lights (usually 500W DRL). It is inferior to them, of course, and because of the power, because of the height and size of the light spot, but in general it allows you to catch even in the village near the lights. Hybrid CFL 26W Blacklight 365nm + CFL 45W 4200K (at 220V) works, according to estimates, no worse than DRV 160W (and consumes more than half as much, and can be safely powered into the cigarette lighter via an inverter, and even with a household compact step-up or step-down transformer up to 100W, if the inverter or lamps are not ours, because that morons in uniform don't let anything on the plane or take it out of their luggage-yes, it happened anyway ). By the way, such a hybrid often gets things that don't fly well on the DRV, especially from twilight species, if the screen is positioned correctly. Wanted, being in the States, poyuzat hybrid 40W CFL UV 365nm + 108(!)Vt CFL 4200K, but unfortunately, it didn't work out. Such a hybrid should be cooler than the 400W DLR without phosphor, and much more convenient. We have not yet found such UV CFLs, and powerful ordinary CFLs can be obtained, but they are indecent. The best screen for such a hybrid trap, in my experience, is a synthetic mesh, not even specially reflective (ta-even more so), it works better than a sheet, and, in addition, 360 degrees. And, of course, it is advisable to remove the diffusers of the lamps, otherwise they are of little use at all. Yes, and glasses are desirable, even 9W UV after a full night gives some unpleasant pain in the eyes. I wear anti-Uv glasses in my life, but I still try to be careful, and with 26W I wear special ones over them (for working with laminar flow). Sorry for the long notes, led, the topic is close, I also like to collect some combination of three fingers . Good luck!

Well, where to fish something I actually have: looked out in advance. There is no extraneous illumination there, and in theory it should even fly "on a candle". But the three-watt Cree LED does not fly a damn thing: tested in practice
And it was caught there a week ago on this so-called "entomofonar" (in fact, being just an emergency lamp), which, having a built-in acc. 6v. 4 A / h. and working with two 8-watt tubes at once, shines for about three hours before full discharge. And it flew at him, taking into account the not very successful fishing time (dubak is already sometimes at night): "don't grieve, mother. "
The essence of the idea is to use ready-made and figuratively speaking "lying under your feet" solutions: bus lamps and batteries that have sufficient capacity with a relatively small weight and dimensions from an uninterruptible power supply. I just asked: has anyone ever used something like this?

Vasily, to catch the difference between this lamp and a regular lamp, it is enough to shine it with UV lamps from the kit, and then they are the same, but with ordinary lamps (today I will bring them to you, they were not in your early configuration). So I think the name is quite appropriate. You can also use "lantern to attract insects", but it's too long.

About the harm to the eyes / health. Not all light bulbs are equally useful. In numbers, I will also clarify the information, but in general-light bulbs from the lantern have passed European certification for harmlessness to health with regular and prolonged human presence near them in the absence of any special protective equipment. Of course, it is not recommended to look at them directly for a long time, but it is also not recommended to look directly at ordinary (non-UV) lamps. And, as Alexander noticed either on the Modeling, or on the store's website, due to the fact that the glow is not circular, it is very convenient to stand BEHIND the lantern and look at the screen and other surroundings.

Peter, so I caught the same on it and flies perfectly: I confirm
I didn't say anything about eye damage. Moreover, I am a bespectacled person and my glasses are glass in my life, and glass, as you know, does not transmit UV or reduces radiation very significantly. So I'm not afraid of UV light. For a long time on my balcony I catch it and my vision is as it was -3, so it remains

This was a comment not on your post, but on the previous one, where the glasses were mentioned.

This was a comment not to your message, but to the previous one, where it was said about glasses.

I understood about the entomophone.
Yes, I just mean that if you are bespectacled, then you should not be too afraid of UV.
And as for the operating time of my system, which is mentioned in that message, I will say that it worked for about 3 hours with all three lamps, in which in fact there are 9-watt lamps, but you can easily take one or two lamps and then the time will increase: this is not critical, because they already shine very well when there is no external illumination. And in a compartment with this UV lamp in general a wonderful combination is obtained

UV lamps in this lamp shine, judging by the photo, not like, for example, widely used all over the world lamps Black Light 365nm. It is necessary to compare them with other UV lamps, and not with "ordinary" ones. I, for example, apparently did not use such lamps, but you can't say for sure. Whether they can be worse or better is unclear, as their labeling is unknown. Is it really difficult to give information?

Well, for example, it is considered that in the fall, in September-October, after 12 it does not make sense to catch, although I left the light on at night for the sake of experiment (after 12) - and in the morning I still collected something...

And according to my observations, it makes sense to wait for 2 hours in the afternoon in September-last Friday/Saturday (September 5-6) just after 2, Allophyes oxyacanthae, Ennomos autumnaria flew (in the Domodedovo district of the Moscow region)

Who used such a lamp?is there a point in buying?

PS The most elementary thing, but it took me 2! years to think of it))) Maybe someone is also not too happy with the convenience of their version, and will take a note.

Question: what's the use of a self-tapping screw in a tree? If your site, then you can also make a crossbar between trees for a hospital. and only hang the screen and lamp. an additional canvas is good only in a hospital setting.
In general, it looks pretty, for me it can be a little wider.

And the crossbar to wind up or nail?)) To my shame, I did not remove the cord on which I hung the screen, and in two years it pulled the trunks so tightly that it hurt my eyes. The self-tapping screw as a solution seemed much less traumatic. And the idea is that the carabiner is removed from the self-tapping loop in a second-along with the screen (its height is about 3-3.20? m, width 1.7)

PS Yes, we are talking about the hospital; I agree with the width - to-height ratio, but I just got used to it.)

Why is it so high? at this height, you can't get anything, or a broken lamp?

There is also a split one ( but, to be honest, I didn't notice any special advantages over a non-split one), and the height is not a hindrance if there is a net.
Heck! I forgot to answer the first question.) Fifty meters from the screen is a 2.5-meter fence, behind which is the territory of an abandoned pioneer camp. And so I thought that it would be nice to have a higher lamp, so that it would fly from there))

The fence is broken, when fishing for light I use a net only in exceptional cases, so I was surprised how to take butterflies from the screen in 3 m. especially micro
