Features of light catching

Which ones? It seems that it is generally accepted that the" cold "DRL and DRV (I'm not talking about the crushed DRL) flies several orders of magnitude better than the" warm "DNaT and"Ilich bulbs".

In general, yes. During the warm season, most species fly to the cold light. In the cold period of the year, it flies well to the warm one. As for the species, according to my observations: Xanthia gilvago, Xylena exsoleta, Polymixis latesco, Trachea atriplicis. If in October and November you look at what is sitting near the light bulbs on the entrances, you can see that there are more butterflies under the yellow ones than under the white ones.

yellowish light also attracts bears and cocoonworms better. even in the summer.

and tufts.

Well, we have in October, and even more so, in November in the city under the lamps usually do not have anything at all, whatever spectrum they may be. Once I only remember the abundance of some moth under the halogen lamps. I've noticed it before. when in November I returned late at night from fishing or collecting blackthorn, those few butterflies that fell into the beam of the headlamp did not fly to the light, but vice versa. At the same time, not a single insect was hovering around the factory building standing alone in the field, brightly lit by both the DRL and DNAT! Here-such cases. So I don't even know what our late autumn moths can be caught with high efficiency. Probably only for pheromones (if they are on sale).

For baits, headlights and head lights

No, I want to go to the light (see the post above). Baits are unlikely - they are mostly afagi at this time of year. Here on pheromones are required. Well, I don't really need it, I used to catch butterflies in the light only for feeding "cattle". Now that the predatory "cattle" has greatly decreased, there is no special need. But when I caught it, I noticed that even 16 W 6000K is much better than 75 W incandescent at any time of the year. But maybe if I'd been chasing quality instead of quantity, I'd have had a different opinion.

In short, I will buy two floodlights, one warm (2700) and one cold (6500), and strengthen them from different sides of the stand. Fortunately, all this bodyguard costs not so much.
Solomon's solution!

Good afternoon! I would like to advise you - my windows overlook the forest, in the spring I wanted to try to catch on the balcony for light. But the 12th floor-I wonder if the butterflies will fly or too high?
In order not to infuriate the neighbors with bright light, I plan to use one UV lamp for the test (will it go for the LH26-FS/BLB/E27 sample ?) and the sheet is like a screen, already lit by an ordinary lamp.
What do you think?

high although you can try

Someone will arrive stopudovo, the question is only in the species composition. IMHO, as an "ordinary lamp", it is better to use an energy-saving lamp with a high color temperature, you should not use an Ilyich light bulb (in the sense of incandescent) in the city (of course, there will be no harm from it, but there will also be a lot of benefit, since there are a lot of similar competing sources around).

The best catch is expected around 3 a.m., when most of the neighboring windows will turn dark.

In my opinion, only a stab DRL in the city will allow you to get a tangible result.
Up to the height of the 9th floor butterflies and beetles fly)

It depends on what is considered a tangible result. If the amount, then after three nights on the energy saving card 15W, sometimes you can roll up a scoop (including a catocal) and leafmakers in cans. True, this is based on my fifth floor, but on the ninth, judging by the contents of spider webs on the stairwells near broken windows, it is quite similar. We don't have 12, so my guess is that everything will be OK there, too, and you can call it extrapolation. If the result means quality, then I can't say anything here, I didn't define anyone, because I caught purely for "cattle"feed. But 15-20 species of various insects (including macro-and microlepidoptera, beetles, bedbugs, orthoptera, and, unexpectedly, ants) were recruited per night, on average. But not everything, of course, is so rosy: bears and hawk moth have never arrived, in my opinion, they usually fly a little lower.

The "mallet" on the balcony of a high-rise building is extreme, however, no matter what the neighbors say (and they will be right).

The number and species composition (including hawkmoth), which then crawls all over the balcony.

As far as I know, there is no violation.

If (God forbid!) If a neighbor's child goes blind, you'll have to prove it in court.

A lot of different if's can be. Foolishly, you can also make a glass one ... break it by cutting your hands )

The catch is that breaking the glass one... only the owner of this-very..., who used it at his own risk, will suffer. From a powerful source of hard UV on the balcony of an apartment building, people around you can suffer, who even have no idea what it is, and what is dangerous. You don't tell them that, do you? At least they went out on the roof or something (if you are too lazy or afraid to go to the field).

We haven't decided on the terms yet. You're talking about the balcony, and I'm talking about the loggia. My DRL is hung up in the back of the loggia (it so happened, due to the design features of the loggia), so that the neighbors, with all their desire, can not get any dangerous dose of UV.

Well, you may have a loggia (which I could not guess, because I am not a psychic), but Vitaly Ch, to whom you advised the "mallet" - the most natural balcony, judging by his words, apparently open.Well, you may have a loggia (which I could not guess, because I am not a psychic), but Vitaly Ch, to whom you advised the "mallet" -the most natural balcony, judging by his words, apparently open. Loggia, of course, saves the situation (from prosecution), unless there is another house right next to it.

The core can be covered from other balconies with strips of tin - this is how I protect my flower beds in the yard from burning out. Catching something else on the 12th floor is simply pointless, since there is so much artificial light around that an ordinary light bulb on the balcony will not leave a chance.

Unfortunately, hide from the neighbors. not hiding from insects is not possible, in the terminal version, only the catcher will be irradiated. At 3 am, there is not so much outside light (unless, of course, it is some "Moscow City"), everything (from what rises so high) will fly to the usual energy saving gallery-just on the way. With DRL (not pricked) - and even more so.

The street lights are on all night and the lamps there are just very bright. And not only "Moscow never slip", other cities too, happens.

We have street lighting at 99% - DNaT, for one such bulb, with all its washing, it flies less than for an energy saving gallery of 6000K. In the central areas of megacities, it is probably really problematic to catch (I haven't tried it), but in the sleeping areas in the second half of the night with light everything is OK.

{We have street lighting at 99% - DNaT, for one such bulb with all its washes arrives less than for an energy saving gallery of 6000K.}

Of the energy-saving ones, it flies best at 6000 + K?

I think so, but there are other opinions, someone, I remember, wrote that some species fly better on "warm" ones.

I don't know about the West, but in our country some species, such as Apocheima cinerarium or Astegania honesta, fly only on the DRL core. You can spend ten years shining ordinary lamps at a point and not meet a single instance of these species. Therefore, if there is no special phobia to the core, it is better not to take risks and shine to the maximum. By the way, the core sometimes attracts daytime butterflies - birch marshmallows and nymphalis regularly fly to me.

Tell me, please - do you need a throttle for this lamp or is it a direct switch?

Look inside. If, among other things, there is a spiral, as on conventional incandescent lamps, then direct switching on without a throttle.

Google says that this is an analog of the DRV (that is, the throttle is not needed, there is an incandescent filament instead), hang only vertically.

Apparently-the usual DRL-250. So, you need it.

If DRV, then it is strange that the base is E40. However, as s585 already said, you just need to look inside.

All sites agree that this is a "mercury-tungsten lamp", "throttle-free lamp" or "mixed light lamp", that is, an analog of the DRV (unless of course the box is mixed up). What about the cartridge? You never know what the bourgeois ponapridumyvayut.

There's a spiral there. Regarding the E40 base, I once had a direct connection with the E40. Thank you.

People, I'm sorry that I don't have the energy to read 67 pages right now! - I just want to ask:
- What influences the degree of attractiveness of a light source for butterflies? (apart from many side factors) - light temperature (K), or oscillation frequency (Hz/Hz)?

Frequency of what, supply current or radiation? If the latter, it is closely related to the"color temperature". But the lamps do not emit a narrow band, but a whole spectrum with different frequencies, so we can only talk about the frequency maximum or mode. The color temperature is the temperature that a completely black body would have if it emitted light of the same (approximately) spectral range as a given lamp. This is an abstraction, and it is very similar to the fact that different manufacturers calculate this "temperature" differently. If we mean the frequency of the current, and accordingly the flashing of the lamp, then I am not sure that such studies were conducted.

I'm far from a physicist, but you haven't answered my questions.
"So what?"- since everything is so blurry/or not explored, is it just a matter of power (W)? And it's all the same to catch something-an ultraviolet light, or Ilyich's light bulb from the toilet-as long as it's brighter? I understand that visually, a modern fluorescent lamp with the same power will look brighter than a toilet.

I went to Wikipedia to see such a thing as"The power of light"... and there in general the devil will break a leg. For example:
"In the system of energy photometric quantities, the analog of light intensity is the radiation strength I_e. Relative to the radiation intensity, the luminous intensity is a reduced photometric value obtained using the values of the relative spectral light efficiency of monochromatic radiation for daytime vision V (lambda)"

You can use the search option. Short answer is difficult, there are many nuances.
