Well, in general, a shirt, especially a summer one, does not delay much, it breaks through the fabric easily! It seems like a contrast, but it's a contrast between very tanned exposed parts and not much-under a thin shirt

But in general, the UV from drlki, although much more dangerous than the sun, is also much stronger, according to books, it weakens, there are very short waves, about 150 or approx. that one.
But nevertheless, I somehow foolishly turned on a similar lamp in Terra with plants, well, there for ozone

, and only 16W, and then not at full power and half insulated with foil!!! In general-literally 7 hours of exposure and almost everything died out!! So you'd better be careful..

That's right, I always wondered how a summer shirt can delay something there a lot...
And in thick clothes in the summer toil somehow not worth it, too...
In theory, the most attractive spectrum for insects is longer than 150. Something there in the region of 300-350, it seems. So there are definitely longer ones, too. And yet how.

Well, I agree that "bioUF" is a spectrum bordering on 400, but the fact is that the crushed DRL alas, slightly less than fully produces 153 or so, but with ka kraz glass, those waves that are about 400 are more likely to pass, so yes, it's better with glass-only physics, nothing superfluous ))

Stop-stop-stop... You turn my picture of the world upside down

, like I thought it was common knowledge that people fly much better to Kolotovaya. I've read about it everywhere. Including here. Yes, and I myself have observed this several times on streetlights. Here last year I caught under the lights on the railway platform. One lantern had a cocoanut bulb , so there were three times as many butterflies hanging out there as on the entire long platform combined. Why do people then prick DRL and are at risk?..
I don't understand

anything

Thank you. Can I tell you more about how to use capacitors instead of a choke? For a kettle in electrical engineering, due to the lack of a machine, the throttle is always a problem for me - it weighs quite a lot. Especially when flying by plane. What should be the standard scheme for the AWACS 250?

I'll reinvent the wheel, perhaps.

Here, the throttle has a clear advantage, namely, the throttle in a sealed case. I put it in my backpack and went (or went). On the spot, it's a small matter - connect it to the wires and the lamp and to the source.
The question arises: wouldn't an alternative circuit be less convenient and less reliable in the field, as opposed to a heavy throttle?
In addition, the DRL-125 flies no worse than the 250, at least in my experience.

And if the use of DRL in the field is unacceptable for you due to the increase in the mass of the structure, then why not use the same DRV together with the black light lamp, which has an E27 base and does not require chokes, but complements the main light source.
In the field, far from the lights, it will be good to fly on the DRV.

Also: don't forget about the weather, moon phase, etc.

Yes, use a capacitor as well as a choke, only with the selection of capacitance you need to guess. Here I have now specifically what is constantly working - this drl 150 + capacitor 20mkf 310V, MBGO, but this is because what is, better MBGCH 300V or MBGO 400V.
MBGO can break through to 320V, here as luck would have it, I had one warmed up, and the second turned out to be better, after all, the USSR, you can see in reality for 325B the real threshold was) It weighs less than 100g, probably 60 grams.

You need to select it, you can calculate it in theory, but in reality it is better to choose it with current control. If the capacity is less, the lamp will burn dimly, it will not enter the mode, if it is more, it will melt 100%

Thanks! I'm just going to try the DRV 250 + extra lamp.
But after all, the capacitor can also be securely mounted in a sealed case - this is not difficult. There will be a big gain in weight.
To be honest, I was disappointed with the black light lamps. It seems to me that they are very weak flying. I bought lyumki Repti Glo for a terrarium-the spectrum seems to be more attractive than promised.

Only those who have not had a full-fledged experience of fishing with a split lamp can compare the effectiveness of a split and non-split DRL. What 10-20 %. People don't write about what you don't know. The difference is in the order of both quantity and quality! Yes, the danger to the health of the mallet is very high and safety measures must be observed.
1-the lamp must be hung at a height of at least 3,5 -4 meters. Accordingly, there should be a second lamp on the screen itself, so you can use an energy-saving device.
2-lubricate all exposed areas of the body with a cream with protection of at least 50
% 3-glass glasses on the eyes.
4-turn off the beater once an hour for 10 minutes
And you will be happy!

There is an opinion that thin summer clothing such as a T-shirt will not protect you from DRL. We are talking about the areas of the body that are closed by it.
That is, the split DRL is hung not in front of the screen (it is rarely possible to make a screen 3.5-4 meters high), but above it?
Is there any danger that the majority of butterflies will fly around the AWL and not land on the screen?
