People, help, please, where can I (exactly) get an ultraviolet lamp for 250 W (exactly for 250!)?
maybe someone will sell it or tell you where or from whom it is sold.
it is Uv that is needed, and not any other. Halogen will not roll, DRL/DRV too (especially DRL, as you do not want to mess with the connection, create a circuit, alternative throttle, bale the flask, etc.)

Here, by the way, in just field conditions, in the absence of visible light sources within a radius of several kilometers, any lamp, including 20W, will do. Even the DRL flask does not need to be pricked. If you do not want to drag and connect the throttle, then there is a throttle-free DRV for this (although if you split it, the arc will cover). If there are lanterns nearby, and "windows have an unquenchable light", then only UV or split DRL with all precautions taken.

As for the wavelength, you need to search, but about the power, it is known for sure that the most attractive power of a UV source is 250 watts. Gornostaev has something about it somewhere.
However, you can catch and so (in a completely wild area): use two DRL/DRV lamps of different power (for example, 150 and 300 W), turn them on alternately, first the more powerful one, then the less powerful one. The principle of the method is as follows: some insects rush directly to the light source, some-sit down a little further away. When you turn on another lamp, they fly to the screen. I used it myself, the method is effective and well described.
As for the sale of lamps that do not require a fixed connection, you can dig through sites with entomological equipment or find special fluorescent lamps in specialized stores.

The DRL lamp itself looks like a large bulb with a cartridge. The light source is a gas-discharge burner (mercury-tungsten), which, together with ballast resistors, is hidden in a flask covered with phosphor and filled with argon, this flask, i.e. the outer shell of the lamp needs to be broken. The lamp is taken, wrapped in a rag in several turns, placed on a hard one and on top with a hammer. Just carefully, so as not to break or bend the filling. Next, the burner is connected to the ballast so that it can be turned on in 220V, usually chokes from fluorescent lamps are used as ballast, pcs 4-6-8 depending on the lamp power. I'll send you the activation diagram a little later. Yes, a 250-watt lamp costs 160 rubles. (Khabarovsk)

For those who prefer to protect their eyes, there are sunglasses. Well, of course, I don't think you should look at it directly.
In Moscow, there are also 113p (of our production), but a little more expensive. Throttle (for DRL-250, right there it is special and sold) - no more than 500 rubles. The connection diagram on the throttle is usually drawn. We connect sequentially and no problems.
As a doctor, I must once again warn you that careless handling of a hard source of ultraviolet light can lead to photodermatitis, hyperpigmentation and, worst of all, to melanoma (discovered America, of course). But this is not so bad if you are not constantly in close proximity to the lamp and if you do not have too white skin (types I-II of photosensitivity). In strictly dosed amounts, UV is even useful.
By the way, I work in a country clinic and recently, while staying on duty right from the office (my window looks out on the forest), I caught some lovely spring moth and a scoop (Phigalia pilosaria, Agriopis marginaria, Lycia hirtarius, Biston stratarius, Eupsilia transversa, Lithophane hepatica, Lithophane consocia).

2 Morozzz: Write what I can, I'll tell you (Presid_11собакаmail.ru). And what kind of lamp from medical equipment? Actually, I am also puzzled by the reduction in weight-gluttony-danger of UV lamps. That's why I asked about the germicidal lamp. El. it is easy to make ballast for her, she eats little, she doesn't try to set fire to anything around her.
2 All: Messages about flashlights with UV light-emitting diodes (from keychains-children) skip through. currencies). Who-thread made similar lanterns? what are the results? I couldn't get such LEDs myself, we don't sell key chains, and suppliers of radio components don't have such jokes in their warehouses. The directories have them, but.... I tried to use lamps from bank children. currency, somehow not very, maybe someone has thoughts about this.

The bulb is covered with phosphor inside. Having split the flask, namely DRL, (carefully, without damaging the arc), you get a reliable and quite durable, protect only from moisture, a source of strong ultraviolet light. In an area where there are already so many lanterns , this is probably the only effective light tool for attracting insects. They fly so fast that you forget about everything! However, it is necessary to hang such a lamp at a height of about 2.5 m, some kind of hat, dark glasses should be taken.
And the screen - you probably know it as well as I do.
Where the nearest light source is many kilometers away, you can catch a whole car on 150 W DRV.
If the question is about splitting the DRV , then she will not live at all after that (at least from personal experience).

to taler: I personally caught a marigold Hipparchia fagi in the Krasnodar Territory.

We saw these actinics and superactinics!
It is good to use them again - where there are no nearby light sources, namely within a radius of several km. And then, no matter who you look at-all lamps like DRL and DRV.
I repeat: I use DRL (HLV) -250 with a split flask. I connect it via the throttle. In the conditions of the Moscow region, they fly even on a moonlit and frosty night. Only, however," bunny " caught on the night of May 14. Barely got home.
I also tried on DRV (ML) -250 (throttle-free, do not prick the flask - it will spoil) the weekend before last. They also flew well, but not so thickly. In addition, in both cases, lanterns with DRL-300 or 400 W lamps shone nearby, but none of them flew a single butterfly. They flew only to mine.
Somewhere in the wild, you should try a good method, I have already described it earlier. It is used in his expeditions by Viktor Sinyaev. Two DRL (or DRV) lamps of different power - 150 and 300 watts are used. We turn them on one by one. The essence of the method in particular of many moths (and not only butterflies) do not fly directly to the light source, but sit down at a distance from it. When you turn off the more powerful one and turn on the less powerful one, those who "landed" further away fly closer.
