Features of light catching

This is probably a mercury-tungsten lamp, i.e. DRV, a mixed-light lamp. According to the characteristics, as far as I understand it, it is close to the DRL, but IMHO, I compared the design of the DRV-250 and DRL-250, in the second the mercury lamp (bulb) itself is much larger, and in the first it is smaller and part of the light is emitted by an ordinary tungsten filament. Thus, I assume that with equal power, the DRL lamp should be more effective, since it is a pure mercury lamp, and not a mixed light. I've already bought one for myself, and I'll try it out as soon as it gets warmer. I've been fishing on the DRV for the last few years, but I got the impression (I've already written about this) that the DRL still flies better, I assume that the DRL still has a large proportion of ultraviolet light.

Tell plz about the catches on DRL 250! I'm just going to catch the first year... Who flies (Moscow region, Tambov), how, at what time it is better to catch, in what month! I just want to get ready for the season!

you can fish in any month (from mid-April to about mid-October).
A lot of things can fly, but you can't name them all (take Sirotkin's list). At what time-it all depends on the month and the time of sunset, in general-as it gets dark and even before the morning, you can do it earlier...
In drizzly rain and cloudy weather, the years are better, with the moon - worse.
In general-experiment

The boy wants to go to Tambov, you know it's Chiki-Chiki-Chiki-Yes!

I'm going to design an installation on Monday like Musson_max, which is on page 8. Since I don't have a dacha, I have to travel around Moldova, I don't know who to stay with, I often have nowhere to hang a lamp with a screen, or it's not convenient.

Such a question appeared..
DRLki are powerful, the light is scattered all over the area, does this prevent fishing?Those. many grandmothers and beetles do not reach the screen, but sit on any illuminated surface around..
Shouldn't the results improve if you do it according to the following principle:

Shouldn't the results improve if you do it according to the following principle:

So for this purpose, a second lamp of lower power (125W) is used, or even a simple incandescent lamp. Alternating their inclusion, we achieve the best result. Those who crouched further away will fly up to the screen. When I started fishing like this, I improved the result. It used to happen that at 250-watt, the summer intensity begins to subside a little after an hour, then I turn on the DRL-125, wait for it to light up, turn off the 250. After 5-10 minutes - an" update", and a radical one at that. Half an hour will work, I turn on 250 again, wait for it to light up and turn off 125. Next-I repeat again.
The graph turns out like this: for example, 23:00 - 250
00:00 - 125
00:30 - 250
01:15 - 125 and so on

Have you noticed any changes in the composition of incoming beetles?

Somewhere before one o'clock in the morning, carabids, staphylinids, and small water lovers fly, and barbels fly.
After an hour-mostly water lovers.
At a later time, dead eaters also fly.
The most intense years of beetles in the first hours and when it's warm.

well, first of all, lucanids and rhinos arrive.. and there is also a trifle like vodolyubikov, plavunok, gladyshev, small carabids, then, according to my observations, somewhere after 23 barbels come, after an hour somewhere there may be dead eaters, sometimes kalosomes, up to an hour still fly bostrichids, vagabonds, somewhere up to 12 scarabeids like serika, ochodeus, rhizotrogus, maladera, melolonta, odontaeus, bolbelasmus.

  
hang a lamp with a screen is often either nowhere, or not convenient.

It is not clear why it is sometimes impossible to hang up the screen? I have nothing against different installations, the one in the photo is very interesting by the way, but in my opinion it's easier to hang the screen in any case - you pull a string between some poles or trees, hang a canvas on it. For the lamp, you can pull a second string.
The installation in the photo still needs to be fixed with tripwires, and if the structure is made of pipes (already cited by someone above), then these are dimensions, weight, assembly and disassembly. In general each method has its drawbacks :- )
Personally, I'm going to try out the two-lamp technique described in the article by G. N. Gornostaev in the summer (the link was somewhere above).

And through one throttle two lamps can be held!?

Twine is still a little off... not mine.. And to drag the pipe installation, I think bedt is not difficult and not troublesome.. Must try..
The installation in the pictures is also, of course, necessary to install, but there at least everything is with you and this, in my opinion, is more convenient, is it more efficient?

Two lamps are good, but connecting them is also not always convenient.. The problem is that I do not have a fixed place, and breaking into unknown people's hut with two healthy lamps, e despite all their kindness

And through one throttle two lamps can be held!?

no, each lamp has its own throttle. K 250 - your own, k 125-your own.

I'm a little off the mark! Is it possible to pass two DRL250S through one throttle for DRL250!? Just buy your own throttle for each lamp....

I'm a little off the mark! Is it possible to pass two LHK250S through the klby throttle for the LHK250?!

IMHO, no.

By the way, the throttle for a more powerful lamp can be used for a less powerful one, at least the throttle for DRL-700 works calmly with the DRL-400 lamp.

I'll pay my three kopecks, maybe someone will need it.back in school, I came across an article about fishing for light and decided to try it,in those early days it was expensive for me to buy a mercury lamp and I started with alternatives.I tried all imaginable lamps,fluorescent ,incandescent and finally bactericidal-all this turned out to be complete bullshit(it is understandable for insects to give ultraviolet light, I didn't know it then).Finally, I bought a household irradiator with a quartz mercury burner.The name of UFD B is kind of like that.The weight of the unit is about a kilogram, there is a tricky design, the developers abandoned the throttle and instead installed two thermoelements as a ballast...they warm up, which is unpleasant at first, but the weight decreases decently.the power of the burner itself is wat 100 to mine.I went with this device to the Caucasus many times(there ,by the way, the death's head flew to it somehow)and to the Far East and to Astrakhan and everywhere...the thing is extremely catchy and light.I really put her on the ground and spread the screen out in front of her..I don't know but it was more convenient for me to pick out interesting samples because sometimes hundreds of grandmothers fly together and we should not miss interesting things...another positive aspect of this device is that nni has never caught conjunctivitis.Now about the disadvantages of the main and only low power, on moonlit nights very much suffered...years are not the same and a lot just flies by..In addition, I caught 400 watts on the same lamp several times,but I don't remember if this monster weighs 12 kilograms.Here it was the strength of the pearl on it is just a terrible amount and do not care about the weather...However, in the morning, almost all fishing participants usually lay around with the strongest conjunctivitis,it was difficult not to catch a bunny with this monster.Vobshcheto nothing new I have not reported here the idea is simple powerful mercury lamps of high pressure and you are a winner.

Now about the disadvantages of the main and only low power, on moonlit nights very much suffered...years are not the same and a lot just flies by..

According to Gornostaev, this is not a disadvantage of any lamp, but a feature of insects that do not fly into the light on moonlit nights. On moonlit nights, they simply do not need to use the light from sunset (or lamps) for orientation, the terrain is already quite clearly visible, so for orientation on such nights they use vision, and not the direction to the ultraviolet source. It seems to me that this is a plausible explanation for a bad summer on such nights.

And I read Gornostaev...however, practical experience does not contradict...it's just that insects fly better on a high-pressure mercury lamp with a power of 400 W on a moonlit night than on a 100 W lamp))) about the reality of using LEDs or xenon, I did not write because there is nothing to write about it...

I recently bought a light bulb "LUF-T6", in "Medtehnika". What is its power and pressure? Will it catch you?

By the way, bills from it do not glow...

Here is the TTX of the lamp:
http://www.vniiis.ru/luft.php

There is indicated (for my lamp) power-6 W, and the radiation flux in the UV-A region - 0.6 W. But that doesn't mean much to me yet.
Will Zhuzhlo fly? And how?

it won't,it's a low-pressure fluorescent lamp, and the power is ridiculous...well, it is clear that it will arrive, but do not expect such a shaft as on high-pressure mercury,imho a pocket flashlight is the same...

Still, I don't think it's a good purchase. My choice-DRL-250 kolotaya

good day!

With long trips to remote areas, the issue of fishing for light is very acute. After all, it's one thing to see what kind of wildlife during the day - it all depends on your desire to explore. Another thing is night fishing-often there is simply no electricity, or the battery is very weak, etc. etc. Generators are good vesh, although expensive, but if only there is a car-you can not worry about the weight of the generator, and you can take fuel with a reserve. Another thing is hiking-there are many advantages in it, but as for the devices for night hunting - here is a complete failure... Every extra kilo creates a lot of problems
I tried a lot of options, recently I was hoping for new developments, but it didn't work out, and it doesn't seem like Africa, and it's very difficult and expensive to get such equipment.
I was advised to buy a 60W lamp with 40 batteries (nickel-metal hydride) and solar panels (depending on the power of 25-10). It is quite difficult to solder this whole structure, but if you do-it should be cool, you must protect the solar panels from below and from above - plexiglass is suitable for this (you can also use duralumin or something similar from below). Lithium-ion batteries are good, but their life is no more than 3 years, and NMN with proper handling will last more than 5-7 years, and their price and capacity are much higher. The total price is 200 Yandex units.
Maybe someone uses such a thing?

For 200ue, you can take a cheap gene...
On the" Babkin " wheelchair screwed, the throttle with a fuel canister in the same place... In the forest threw, covered with lapnikom and run until the night, butterflies chase!

Well, it depends on how many people roam in the forest, and then at night, running with butterflies, you can get an unpleasant surprise...

Well, there is such a risk, of course...
Only here we were talking about places that were deserted, without electricity, etc...
By the way, I do this at my dacha... While lucky...)))

I often hide my clothes in the woods so I don't have to carry them. But the risk is still quite high...

Які поради...
З колясками по лісу, по полям ще більш-менш, а як у горах? Хотів би я побачити ентомолога який тягне за собою 20-кг коляску по камінню, по схилам ... Гадаю, така-б картина запам"яталася на все життя

Yes, 20 kg. generator of course in a wheelchair from the dacha to the forest can be taken out, but in a serious trip, where the places are really wild and deserted, you can not trample it with you without a car, because you will have to take a tent, food, etc. life support. Oh, by the way, an entomologist dragging a generator in a wheelchair through the swamps will look no worse than in the mountains...

We discount electricity supply to forests and fields!

there are generators and 9 kg in weight, about solar panels and accumulators I think it is unlikely to ride...the battery is good if, for example, a satellite phone is charged ,and for a lamp of 60 W, you probably need to do a pretty good size, this will cover any generator

I once saw on sale a solar panel that could power a portable TV, i.e., about 12W. Its area was about 1 sq. m., and the cost was about$100. If you try to calculate, then this is 12 V at a current of 1 A, and let's say the sun shines for 9 hours a day. So in one day of perfectly clear weather, we will be able to "fill" into the battery (1 x 9)/1.5 = 6 A/h. This is enough to shine 6 hours with a 12W light bulb or 1 hour with a 72W light bulb.
In reality, it will turn out less, firstly due to the fact that it is necessary to supply more than 12 V to charge the battery, and secondly, ideal weather rarely happens. All this will lead to the fact that the battery will fill up not 6 A/h, but less. In addition, the mobility of such a system is zero. So I can't imagine how this option can be applied in hiking.
As I already wrote in this topic, when hiking-a lantern on your forehead, a net in your hand - and go!: -)

Good afternoon!

Can you tell us where in St. Petersburg you can buy a black light lamp
(suitable for fishing on the light)?

Damn, it's a pity Tesla buried a bunch of his ideas, so now it would be possible to turn on

Well people!!!
Do not judge strictly my "drawing" abilities... )))
For people who have just signed up...
Version approved by most of the results of 12 pages equipped with a split / non-split DRL 250 (a large light bulb that does not work without a throttle)...
The kit will cost about 1000 rubles... well, respectively, without rags and a generator...
So for beginners, all questions should be exhausted with this post!!!
here!!!

well, guys, what are you doing the same thing, too doldonite, so a few people suggested ... and again this bodyaga begins...americanecz drew very well...I really love the screen on earth,but maybe I'm wrong...there is no freebie in life...DRL plus generator is a killer combination...and to dream there about all sorts of solar panels is not yet realistic..I can't even charge the camera with this, although I don't have any budget restrictions at all...... (such cases)

I propose to discuss the following problem. Everyone knows that females of some species of butterflies come to light much less often than males. Are there any ways to solve this problem? I, for example, have been trying to get a female Laothoe amurensis since 2000 and all to no avail, although males arrive regularly, and sometimes in large numbers.

um...I didn't think twice..I always attributed this either to fluctuations or to different periods of summer...maybe you're right..

And I wonder-do daytime butterflies fly to the light of such lamps at night???If they're flying, what are they?

I caught Pieris rapae, they told me about Inachis io, a million thoughts come to mind, what kind of animal is this at night, and then there is a long rzhach about these assumptions.
