Features of light catching

Well, I'm a Muscovite!
Basically, it doesn't go any further than the dacha...
I have dachas in the Ryazan region, not far from Dubna and in Sergiev Posad!
Here!
I don't know where you catch...
But so that the sheets can't be seen...
I've never seen it!

Just like Stalin's:)
"Near Dacha", etc.

Good fishing is when you come for the right species and catch it! Or at least 1-2 new species that are interesting to you arrive. So you should always catch it.. in general, as he himself noticed, the best years begin in July and continue until September somewhere.. Until the cold weather comes shorter

A good year can be from March to November! And this is in the Moscow region.
Only the greatest variety will be from June to August (also for the Moscow region).
I will repeat once again (this topic has already been written about this): THE BEST CONDITIONS FOR NIGHT FISHING ARE A WARM, QUIET, MOONLESS, PREFERABLY OVERCAST, EVEN WITH A FINE DRIZZLE, NIGHT.
Under these conditions, your screen is still likely to be visible, but it will become very colorful.
If the moon is in the sky, then at least howl at it - they won't come particularly. I've watched it myself - as soon as the moon comes out, only the polar bears of Spilosoma spin. They don't fly in strong winds either. Although there are exceptions - in Anapa, I remember on the embankment flocks of bindweed hawks flew over the mimosas shamefacedly, sucking nectar, and the wind was strong, but they did not care.

to americanecz: Can you tell me exactly where your dachas are? All three districts are interesting.

My Dolbinka flew in on a clear night, but the moon was just beginning to grow..

I spent the whole summer catching 700 watts on DRL and mostly midges flew (I took the screen from the projector ), but I need butterflies! and you argue 250 or 500 watts!
kilowatts for 2 lamps to look for!

2 Alexander
is not the first year I catch on 250W, it happens that in addition to a cloud of woodlice, nothing flies, but mostly butterflies, a few beetles. Everything is in a decent amount, it would be interesting to read the report on fishing for a 2KW burner.

But I was wondering if I had an ultraviolet lamp at home,a real,decorative one, the kind that bars hang out for illumination .All light tones reflect light.For those who understand-a girl in white underwear lying on a dark bed looks very effective.
So, something on this vaunted ultraviolet none of the insects do not fly or crawl...Maybe the light is wrong, or nasikomye not the same?!

Colleagues, such a question, I found on sale LEDs in the UV range, 400-410 nm, 100-150 MKD of aperture (or whatever it is called, maybe brightness). If you take 10-20-40 pieces of them, and make a lamp out of them. Advantages: low power consumption (many less drl) and light weight. I'm interested in your opinion.

The idea is interesting...

Yes, it's great, you can try it. The most important thing is whether it will work?
Make, test, report. We will be only too happy.

Of course, one of the criteria for the effectiveness of a lamp should also be how insects will fly at it in the presence of lanterns nearby.

yeah.theme with diodes and me interisuet

With field tests, as well as with the report, we will have to wait until May
I found information on the Net suggesting using UV LEDs, but I didn't see any results. Now I am interested in two questions: the wavelength (spectrum) is suitable (see above) and how many diodes to take for the equivalent DRL-250.

Now we are interested in two questions: the wavelength (spectrum) is suitable (see above) and how many diodes to take for the DRL-250 equivalent.

As I understand it from here in DRL, the radiation spectrum has maxima in the region of 350, 400, and 440 nm (ultraviolet, including hard light) and 550-580 nm.
But you need to take as many diodes as possible. In addition to their low power, the spectrum may also have been adjusted for safety reasons (hard UV is removed)

If memory serves, the visible part of the optical radiation is between 380 and 780 nm. The figure (link) shows the DRL spectrum after UV radiation is converted by the phosphor of an external bulb. I wonder what the spectrum of the mercury burner itself is, I'll look at it at my leisure. Hard UV in the LED can not be, the material (plastic) will not withstand it. The wavelength of UV LED radiation at the border between UV and visible radiation, without harmonics (i.e., hard-coded), I wonder if butterflies will "like" it? It is problematic to take a lot of LEDs, it will be a very bulky design. And you can't compare the power consumption (250 W DRL eats, but it doesn't shine on them) It is necessary to compare by some "optical" parameters, but by what ones?

This year I took 5 purple LEDs, in my opinion, about 18-30 cd of power each. I tried to catch on the received light. The effect was not very good.. Of course, various nasty things flew in.. - a bag holder, a couple of small dustpans, some smoothies (small) and some other nasty stuff... generally not thick-drl is better in mld raz

I found information on the Net suggesting using UV LEDs, but I didn't see any results.

At the expense of field tests. There was a case! But not UV, but ordinary bright diodes. Blue-white light.
The CATEYE OPTI CUBE HL-EL300 bicycle headlight was used. The headlight is equipped with 5 diodes, powered by 4 finger batteries with a total voltage of 4.8 volts. In the forest, in a clearing on the mountainside, a sheet was stretched, the light from the lantern was directed at it in such a way that it turned out to be a bright spot about 50 cm in diameter. Some of the light was out of focus, so basically the rest of the sheet was more poorly lit. There were no competing light sources. A second sheet was spread out on the ground under the first one.
The lantern burned for several hours, and the sheets were checked several times. All this happened in the Crimea, in the middle of April.
Results: At nightfall on the sheets gathered probably about 100 or even 200 of some small reddish crunches, stuck all! In the next few hours of years, Khrushchev greatly decreased. About a dozen scoops and a few moths were also spotted.
Considering that in April we still have a small night flight, as well as that the system turned out to be autonomous and not at all heavy - ropes + sheets + a lantern in the amount of about 1 kilogram, the result seemed quite acceptable to me.

And another, active method of catching on diodes:-)
I put on a head-mounted LED flashlight, take a net and inspect the night forest and lawns - a lot of animals! One of the advantages of this method is that you can collect butterflies that are indifferent to light - I caught them right next to the OSRAM HWL(MBFT)lamp that is turned on225V E27 250W (mixed light bulb) - they flew in the bushes nearby, did not react to the lamp.

With the onset of darkness on the sheets gathered probably about 100 or even 200 of some small reddish crunches, stuck to everything! In the next few hours of years, Khrushchev greatly decreased. About a dozen scoops and a few moths were also spotted.

The most interesting thing is that in the last decade of May, in the very south of the Khabarovsk Territory, this year there was about the same situation, only the lamp was AWL, and in addition to beetles, a cloud of woodlice arrived, and that's all.

Who is interested - practical experience of getting burners from any lamps with 100% output.

We take the DRL lamp. We stick a strip of scotch tape near the base (it is necessary so that the flask does not crack ahead of time).
We take a triangular or square file section (well, or a small file, small bars are also suitable for sharpening knives).
We spit on a strip of scotch tape and begin to cut through the glass with the edge of the file directly through the strip. Periodically we spit in the same place.
When you cut deep enough, you will hear "SHH-shh-shh".
All. Further, the flask is disfigured in any available way-it beats with a hammer, it is chipped with pliers... I personally prefer to cut the same file in a circle, then tap it lightly on the file and remove the entire flask.

!When broken with a hammer, the burner bursts from a pneumatic impact: the flask usually has a low pressure and if it is sharply broken, a sharp atmospheric pressure shock is obtained on the burner. Only a few survive.

And to filter out visible light so that only ultraviolet light can shine, has anyone ever tried?

As far as I understand, the phosphor on the bulb converts ultraviolet light into the visible spectrum; and through the coating, u. f. passes weakly. so it doesn't matter if the visible light spectrum is also there or if you filter it out.

In preparation for the spring, I collect the "technical component".
Personally, I am very interested in what kind of animals will fly ONLY in ultraviolet light without visible radiation (for me this is important).
I plan to test experimentally the effectiveness of various UV sources ("black" fluorescent lamps, UV LEDs, medical "bactericidal" ones).

Good idea.
I think that others should support this as well. Everyone, for example, would use different lamps, then investigate the fees, conduct a statistical analysis of the collected data. The main thing is that the external conditions when using different light sources are comparable.

this is my message that I didn't log in, but?

My "love" is probably a stab DRL

who can recommend an affordable material that transmits ultraviolet light and delays visible light?

The main thing is that the external conditions when using different light sources are comparable.

In order for the experiment to be clean, you need to catch simultaneously on different sources, while spreading them not very far from each other, but so that they shine simultaneously.
In the summer I caught at the dacha, I noticed that some views of my DRV-250 lamp do not fly, but they fly to the window of the dacha lit by an ordinary light bulb.

Also in the summer every day I catch on the DRV-250 lamp at home on the balcony. I noticed that, for example, on three consecutive nights identical in weather, different species fly. On one night, some species predominate, and there are no others or very few, on the second - other species, and the first almost none, on the third-third species fly en masse. And such a situation is common.
It is clear that this depends on the weather, but on what exactly? Outwardly, everything is exactly the same-wind, temperature, humidity...

Someone suggested the option of connecting the DRL without a throttle, please respond.
Tell us how to light up a broken DRL. I bought a lamp, how to light it?

As a person who is not friendly with electricians, I recommend spending money on the throttle. A circuit with an incandescent light bulb is fine, but it's better to have something more reliable. The connection diagram on the throttle is usually drawn (sequentially). Methods of splitting the bulb, further use, precautions and possible consequences of exposure to harsh ultraviolet light on the skin and eyes are described in this topic above.
If the question is the price, then in specialized stores in Moscow, a set of two DRL-250 lamps( one in stock), a throttle and a wire will cost 600-800r.

Store the cracked lamp in a dry place.

There are lamps that look like DRL, but work without a throttle. If I'm not mistaken, they are called DRV (I have just such an OSRAM HWL (MBFT)225V E27 250W)
Inside she has a small cone, apparently ultraviolet + the usual incandescent spiral. Can anyone tell you how much such a lamp differs in spectrum from the DRL?
The same thing or maybe I use it in vain-maybe it's better to get confused and buy DRL+throttle? Or maybe it's better for everyone to switch to the DRV and not bother with the throttles?
I'm with an electrician on "you", but just DRL never even held in my hands, so I only know about it only by hearsay.

Can anyone tell you how much such a lamp differs in spectrum from the DRL?

As far as I understand, the UV component of DRV is filtered by the glass of the outer bulb.

to okoem:
Yes, and I use DRV-250, only in the country, where there are a lot of lanterns, it will not be enough sense from it. Split the DRV - spoil it. This is the disadvantage of the DRV.

Gentlemen,
are there any lucky owners of portable gasoline generators among you?
if there are any (or at least something in this section...)
Help me choose something!
I only need it for fishing, so please advise me something easier and cheaper...

I took a Honda to Africa in a suitcase, it weighs 10 kg, the car is very good. Only expensive...

I'm not interested in manufacturers...
I'm interested in specific models!

Yes!
and one more thing...
I'm quite confused about the quality of my equipment...
But I'll make a living in other ways...
and spend a mower of green to catch butterflies, I don't think it's appropriate...
at least not for me...

I'll tell you even more!
I need something cheap!
to keep one light bulb (drl250-400)!
And just delov that!
