Hello dear friends! From the black UV lamps shown in the photo above, different fabrics glow differently. Agro-fabric has a gray dull shade, HB sheets glow bright white and synthetics bright bluish. Which of the spectrum reflections is more preferable or it doesn't matter?

I had the following experience. The screen cloth was sewn from two pieces of plastic fabric, from which they sew bags for flour, sugar, etc. Such a weave of narrow ribbons, I don't know how it is called correctly. So, one half glowed in UV bright blue, and the other half was simply illuminated, but without the effect of fluorescence (the fabric was different). From experience, I can say that the part that shone brightly in UV attracted insects several times less than the second, dimmer half. At first, I was surprised by this. But then I thought that probably the dimmer half reflected invisible UV without changes, but the fluorescent fabric converted UV to the visible spectrum, which looks like a brighter glow to us, but is less attractive to insects.

Quantitative comparisons have not yet been made (this is actually not so easy), but subjectively it seems to be the best special synthetic mesh that reflects UV. It is stretch, so a cut length of 2 m and a width of 1.5 m is enough for a screen of at least 2. 5x1.8 m with edges on clothespins. It has a rather small cell and it does not really cling to plant debris. Removing insects is not particularly difficult than removing them from a sheet. Sails much less than a sheet or spunbond, which in some places is blown away by the wind, as if you do not support the screen. At the same time, it is more effective than a window grid and easier to clean from the remnants of past fishing. Subjectively better than other materials both when fishing on DRL+UV or DRV+UV, and, in particular, if fishing goes only on UV.
Some photos are attached:
1) a general view of the screen with a phosphor fabric under the DRL 125W+UV CL 26W and a window grid under the UV CL 26W at the beginning of fishing;
2) a view of the phosphor under the DRL 125W+UV CL 26W 40min after switching on (another point);
3) the same, close-up, the fabric structure is visible;
4) the same, but the Osram 160W DRV is added to the window grid. At the same time, more people arrive under the AWL. With the same lamps, it also flew more (but not several times) to the phosphor grid;
5) I didn't find a photo of the phosphor grid illuminated only by UV, but it glows with a pleasant blue light

. Here is a photo with illumination from a fairly strong frontal lobe (except for UV).

Unfortunately, I learned something after a trip to the Volgograd and Astrakhan regions in May. The beloved KIPOR 2000i just before leaving was suddenly needed for life support of a dacha with a father-in-law, mother-in-law and child, and I had to urgently purchase something else. I have long been relaxed about buying a smaller generator, especially since 2KW seemed clearly redundant for the set of lamps that I usually use (a 2KW Kipor easily ignites and pulls 3X500W DRL). Saving gasoline would allow you to take a 10l canister, not 20l, for points with a separation from the track for 3-5 days (my car eats 95th, so its spare canister is not suitable for the generator). In total, this saves a significant amount of space in the car. And you never know, I'll go anywhere without a car (this was complete nonsense, I didn't go anywhere without a car, but with a generator, I didn't go for many years).
A search on the Internet showed that the minimum weight and gluttony are noted for several very similar models, of which I once looked and was purchased in an online store for ~12000r PATRIOT 1000i. Since in appearance and according to the stated characteristics it is very similar to the Earthquake IG800W, which worked like a bunny in the States and is really probably the best compact generator for a reasonable price (about 350 USD) on the local market (and you can still return

it after a while), I presumptuously decided that the PATRIOT is the same the same thing, but for Russia.
As always, wrap everything up before leaving, and not only did I not check it, but I didn't even take it out of the box. I bought, however, the oil that is indicated, and a canister of 10 liters of 92nd gasoline at a normal, proven gas station. So, still, I was a little worried. On the first day, after driving 1000 km, I no longer had the moral and physical strength to try it out, but right in the morning I filled in oil, gasoline and-oops! - started up with the first jerk. Left to work for half an hour-fine. Well, I think it's OK.
The evening brought unpleasant surprises. It turned out that in economy mode, firstly, it pulls no more than 260W (maximum DRV 160W + 2 pcs UV CFLs of 26W + CFL 40W, with the addition of CFL 11W, the DRV is cut off), and, secondly, the sound of operation is extremely strange-as if it then adds, then decreases the speed. All previously used generators just worked quieter. I expected that in economy mode, it will pull the declared 50% of the nominal value (400 W). Not wanting to put too much stress on the generator during the run-in period, I turned it on to full mode. On it, he lit DRV 160W+DRL 125W+2 pcs UV CFL of 26 W + CFL 40W (working illumination) + another maximum CFL of 85W (only 462 W), the third mercury lamp he did not pull. After 2.5 hours of operation, it spontaneously passed out and did not start for an hour (apparently, while the heat was cooling down). Then it started, I left less than 400W on it, and it worked fine for another 2 hours. The next day, I hung up less than 350W of load and tried to turn on economy mode again. It lasted 2.5 hours and then passed out again, but it started up after 20 minutes (it was much colder

). Then I realized that here you are not there (its Chinese-American counterpart worked for 9h without a break on one tank in economy mode) and moderated the experiments, fearing to remain completely without light. In the following days, I did not turn on the economy mode and did not load more than 350W on the generator, and after 2 hours from the start of operation, I turned it off for 20-30 minutes, after which I started it again. In this mode (2h+2-2. 5 h with a break of 20-30min), it no longer cut out, it began to sound smoother and consumed quite a bit (about 1.2 liters per 4 hours of operation, i.e. 300ml/hour). One night, however, it didn't pull even 350 watts at first, and when I restarted, I didn't close the flap completely after starting up, and it did, and the engine sound was noticeably better than before. I did not take a break from work, and it worked 4.5 hours continuously, devouring, however, almost a tank (1.8 liters, or 450 ml/hour). In general, due to the cold nights, this suited me, but nothing interesting flew for me after 00 anyway. So I can't say I didn't catch something because of the generator. But if the weather was favorable and it was necessary to shine until 4 in the morning, I don't know how it would turn out. In just 7 nights, he worked about 28 hours, consuming 9.2 liters of gasoline (about 330 ml/hour). It took a little oil. No emergency sensors were ever turned on (I'm not sure if they are connected

). I may have come across a bad copy. Low consumption with unstable engine sound, problems in economy mode and normal operation with the flap not closed suggest that the problem may be in the fuel supply. Until you get around to changing the oil and testing it again, and then doing repairs. It is unlikely that sellers in Russia will be able to blow it back.
So, the pros: low weight (8.5 kg empty+0.3 oil+2.1 full tank=10.9 kg curb weight) and dimensions, low consumption, low price, does not leak during transportation, works.
Cons: it does not pull the declared load and hardly 50% of it, no real economy mode is detected, it is unstable during long operation, the sound of the engine running periodically makes you nervous.
I can't recommend you to buy it in any way, but if you have already bought it, do not despair, everything may get better

. It makes sense to look at the twin models under a different brand, because the prototype was good.

The mallet hangs very low, you can burn all the skin, I'm not even talking about the eyes, as well as the plants of friends adjacent to the fence. The split lamp should be adjusted a meter higher than the pole, and an energy-saving lamp should be hung at the screen, 35-45 watts.

And so there are a lot of risks in life that you can add to yourself. I caught it once, on someone else's DRL, with a cracked one (not broken, the flask burst during transportation). You could make a horror movie out of us. Her eyes were red, and the skin even peeled off her lips and ears. How not to watch out, but still with a stab DRV somewhere, you will fall under the ultra-violet distribution.

I recommend, in addition to a wide-brimmed hat and glasses, to use sunscreen with an SPF of 30 and higher.

I don't see any reason why these LEDs should have any special features in this regard compared to any other lamps. That is, the higher the light temperature, the better, and the power - similarly (of course, taking into account the capabilities of the power source). You'd better ask the owners of such devices, not necessarily from among entomologists (rather, from among auto tourists), how long each model is durable and whether it really meets the stated parameters. This will be the best selection criterion. I haven't encountered such lights, but in general, if you need to power them from a portable battery, LEDs are the most important thing, and it is acceptable to switch to "cold" white ones. You can also look for ultraviolet ones.
