Features of light catching

I personally did not understand, is it worth pricking the DRL? I'm only interested in efficiency! Does it improve in the future?

Read Gornostaev's article, everything is described in detail there.

Are the lamps that are sold in pet stores to light reptiles really good at catching them?

What kind of lamps are these? I doubt...

most likely, the height of summer insects also matters..

20% (I think) UV, so that the reptiles would sunbathe.

Come to think of it. If the lamp is located at the level of 1m, the lamp's illumination range is APPROXIMATELY 100 meters in each direction (for example). When the lamp is raised up to 3 meters, the glow range increases by 100+(3-1)=102 meters. That is, in principle, the effect is almost no! The power will not increase, the lamp indicators will not increase either! Only dalnsot glow on 2m and then.... Another thing is to climb 10 meters(from a balcony, for example)! Anyway IMHO no point in raising the lamp!

Standing 700 meters away from the split DRL-250, it cast a clear shadow. So the light from it spreads much further than 100 meters. And you need to raise the lamp higher, especially the stab one. This reduces the risk of picking up "bunnies". And as okoem absolutely correctly pointed out, the greater the angle of incidence of the rays, the fewer obstacles they encounter on their way.

Something I doubt for the shadow in 700 meters.... 30-50, still okay, but 700....

You shouldn't doubt it. The DRL-400 light is visible for 2 kilometers (the distance from my dacha village to the neighboring one).

About the fact that it is visible-I do not argue.The light is generally visible from afar,but the shadow is 700 m away. raises doubts.

I'm coming in, you'll excuse me, you blind people, or what!? I wrote roughly 100 meters, even in parentheses marked that for example!!! Right now I will take as an example 574 meters ... IMHO depending on where to catch... I think lifting the lamp to such a low height will not give results... But this is an empty conversation... I agree about bunnies...

If the light does not fly well, it may depend on the weather temperature, humidity, wind strength, moon phase, etc.
And about the range of the lamp I will say unequivocally-it is better when it is visible from the whole area and as far as possible.

About the flight altitude:
Very few people fly above the treetops. In general, the main mass is concentrated in the undergrowth (if there is a forest, of course)

Choose the correct place to install the lamp.

Here we can also add that the life of beetles, especially ground beetles, depends very much on the temperature. At temperatures below 10 C, the temperature almost completely stops. But the butterflies fly as if nothing had happened.

Yes, at low t, mostly butterflies and diptera fly.

Absolutely agree!
I usually catch it on my loggia, on the fifth floor. In the summer it flies normally, but in the fall it is already bad and by October-November there is practically nothing at all. At the same time, I tried to catch on the street (the lamp is 1.5 meters from the ground), it flies more or less normally. That is, at low temperatures, butterflies do not rise as high as in summer.

About the fact that it is visible-I do not argue.The light is generally visible from afar,but the shadow is 700 m away. raises doubts.

Lots to do, check it out... You go out of town, turn on the lamp, turn your back on it, take 1000 steps, look in front of you, see your shadow. Or you don't see it...

People!
Does the result depend on the noise of the generator?

Yes, it is unlikely.

Yes, gentlemen, compared to your devices, I am like a pithecanthrope who has read about computers (although how can he read something?).
For 3 years I have been hatching the idea to shine a light in the desert in the spring (at the end of March-beginning of April). Alas, there is no transport, and rare visits were limited to the glow of car headlights with constant comments from the owners of iron horses: the battery will run out (if the engine is turned off) or: we will burn all the gasoline (when the generator plows from the engine).
In general, I once chose a self-made lamp that worked from acetylene. Imagine such a 8 kilogram container, water is poured into it, carbide is filled in, and when the "process has started" to a small nozzle with a diameter of a needle, you hold a match. A jet of bright white flame appears. Empirically, you have to calculate the amount of carbide and water, so that it does not explode, and the sun does not shine dimly. In short, on such a canoe, I caught such animals in Moyinkumakh...
I put it in rbkzak and went wild. True, I didn't expect that I would spend so much water on extinguishing it. And in the desert without water...
I had to reel in the fishing rods early, and the catch was often singed by the fire...
Yes, and from the outside probably looked strange...
But I still remember the "guests" who came to this world. Among them are awesome aphodia and nutcrackers, modestly and intelligently landing on the border of light and shadow. And an ichneumonid that stung very sensitively (earlier I didn't know that they could bite). Romanticsm....

Yes, I was also bitten by inhumonides this summer. Just under the lamp. I got into my pant leg and let's sting. I even had to take off my pants.

Heh, I imagine Frost without pants with a net around the lamp running and yelling at the top of his voice.. Well the neighbors were probably laughing

Well, I didn't yell, the neighbors were asleep and no one saw me (I had already turned off the lamp).
But jumped.

I haven't found it in this topic yet:
can I tell you what principle and how to make a light trap? Preferably with illustrations.

A photo of the trap on this page http://molbiol.ru/forums/index.php?showtop...111#entry546111 doesn't fit the page? See Scarabee's post dated 07/28/2007, 16: 34.

This I know, just a more detailed diagram. Does the bucket close at the base of the funnel? Where is the throttle from the lamp? Inside the funnel?

All questions to Scarabee, it was he who communicated with Finn and photographed the trap...

People!
Are all lazy people like that???
You're fucking entomologists, collectors... who else is there...
The process of sitting in the evenings under the lamp should bring pleasure!
It's like fishing almost!
And you simplify everything and reduce all the buzz to zero!

Well, of course, the throttle is located where it should be-near the outlet with a current of

This is for extreme cases, for example, I fished until 2 am in June, and then left a light trap...

I absolutely agree with americanecz!
After all, when you sit near the canvas, peering into the distance and waiting for such a rare and beautiful butterfly to arrive right now, for which you are sitting here, feeding mosquitoes and not doing more traditional things for night time. And then she arrives, at the sight of her you will start to tremble, carefully, with an unruly hand you will put her in the net, then thinking how not to damage the insect, you inject a lethal injection into her small body, then, when her agony is over, you pull the butterfly out of the net and contemplate this beautiful, perfectly whole creature on the ground. in the palm of your hand, with a sense of satisfaction and delight! Then you put it in a bag or on the mattress, again take your post near the lamp, again peering into the dark distance...

There's more such topic.

...... What kind of lamp is that!? .........

Well, a light trap is not for those who care about the quality of the material. You need to return to the light trap before the robin, redstart and chickadee wake up. Especially some mushroom pickers.

This is the question about eye protection from UV :
And the dentist's glasses for light fillings are specially UV-protected, aren't they? and if so, is it really possible to get them?

If only in medical equipment stores. You can probably order it online.

The most interesting thing is that just after 2 nights almost nothing interesting is flying

Doesn't it fly in June after 2? It is in July and August that you can safely catch up to an hour, and in June it gets dark too late. Although it gets brighter early, I didn't catch it later than two in June. But some species fly in the morning!

It is clear that" interesting " is different for everyone. Just my modest personal experience shows that it is after 2 nights that both the total and specific number of insects arriving at the light sharply decreases. Perhaps this is true only for the middle zone of Russia. What is your colleagues ' opinion on this issue?
