I haven't tried it. It is better to fill it in yourself.

I fully support you!
About "immediately burn out" - for those who can afford to carry a generator with them or catch only where there is 220 volts in the socket, such a lamp is not needed and, of course, a generator and a 250-watt lamp are better. But to fish in a place that is several kilometers away from civilization ... Alas, no one has come up with a better and cheaper solution. Well, purely subjective - if three butterflies and 1.5 beetles arrive in an hour, then of course, God forbid one will get burned. But there are hundreds of them flying in places like this. Alas, we have to put up with losses, and if it's such a pity - the problem to be solved is

As far as I understand, the principle of operation is as follows: fuel is supplied under pressure and heats the metal mesh, which, in turn, emits light, including the ultraviolet spectrum, so necessary for collecting insects. Or I'm wrong, if I'm wrong, please correct me. In my opinion, the thing is very useful, especially in the absence of electricity

Yes, you are right about the principle of operation. The only thing: the tube that supplies fuel to the burner has an evaporator ring that must be warmed up before starting (fuel vapors burn under pressure in the burner). I must have some instructions for the Chinese lamp somewhere. If I find it, I'll scan it and post it here. Here's another interesting thing: http://oillamp.ru/links/11.shtml

With an active summer and the "right" weather, it flies to any light. There was an experience of fishing on Chinese daylight lanterns (weak), on an ordinary pocket flashlight and even on a bonfire surprisingly rare things crawled (butterfly beetles fly to the fire, but here they burn down in 99% of cases). But, firstly, this is where there are no powerful or simply stronger light sources nearby, and secondly, the catch is extremely scanty. Therefore, discussing what is flying and what is not is an empty lesson. The main thing is to have an autonomous source of sufficiently strong light. The rest is related to the availability of finances and delivery of this source to the right place.

Evgeny, I totally agree with you. It just so happens that you started this topic, and I continued. Is there really only 2 people in Russia who caught on a similar source?

There is no sign of ultraviolet light there :- ) Energy is not the same. We do not look for ultraviolet light in incandescent lamps, even in very powerful ones that give a blinding light. And the temperature in incandescent lamps is higher than in liquid fuel combustion systems.

The glow spectrum directly depends on the temperature. I don't know exactly what the temperature is in ordinary incandescent lamps, but judging by the fact that the light is "yellow", the temperature there is not too high.
Also, the amount of ultraviolet light emitted by the lamp is highly dependent on the composition of the glass used. It is logical to assume that lamps used for household needs are made of glass that delays ultraviolet light. And by itself, a powerful dazzling light is not yet ultraviolet.
As for liquid fuel, as far as I understand, it is precisely the achievement of a very high temperature (colorless flame) that is necessary for incandescent grids of hot-water lamps.

I think the exact numbers can be found on the web, if you search well.

To all: For the sake of interest, here is a scan from an English book: David Carter "Butterflies and Moths" Dorling Kindersley, London 1992. As you can see, they (the British) use such a lamp, and I tend to trust the British in entomology (Darwin, Wallace, Rothschild, etc.). I propose to essentially share my opinion about catching on this lamp(if anyone caught it of course), otherwise it didn't go there at all. With respect to all, Vasily. Here is the scan:

Pay attention to the words "vapour mercury", which in Russian means" mercury vapor". I.e. in this case we are talking about an analog of DRL. Therefore, it is good to fly to it, because there is a lot of ultraviolet light in the spectrum. In the previous discussion, catalytic combustion lamps were discussed without any mention of mercury.

This year, for the first time, I used the DRL-250 lamp to attract moths.I was satisfied,the result exceeded all expectations.But the season is inexorably coming to an end,and more and more there is this question (before that it was only casually mentioned on the forum), so I will ask it here again:is it possible to leave the DRL lamp and throttle to it right at the dacha in the cold for the whole winter (will the lamp or throttle fail at the same time), or is it necessary to take them to the city and store them there in a warm place?The fact is that the transportation of the lamp in my situation is fraught with significant difficulties,and therefore it is very important for me to know exactly whether to transport the lamp and throttle or not.How to store the lamp directly in winter?Thank you in advance for your response.
