I think locally it wouldn’t work as yet, too expansive, as long as we can drive a car to the place better to have small generator and MV set. But I see it very handy when travel. Sometimes we fly for short vacations or to work and carrying all the equipment for one or two nights it’s impossible plus generators are heavy and not allowed on the plane after use ( filled up with fuel ).

And who will conduct a comparative study. Once upon a time there was GE, Sylvania, Phillips, Osram and ALT. Prior to 1980, they made "all" their light bulbs in the USA. GE had a huge research facility in Cleveland, Ohio, Neala Park. GE has not produced a light bulb in North America since 1986. Every one of the manufactures went overseas.
Today the world of light bulbs are made in Asia, most in China. Most of the new designs originate in the USA. However, lighting technology is slowly going to Europe.
The Chinese are the most aggressive. I average an email contact a day from some China based Light Bulb company. The pricing is great, the problem, you need to purchase two gazzilon for the cheap price.
As for me and Leptraps, we will stick with Fluorescent's. Until such time as I see the real thing.
Google "Corn Light". They are replacements for MV bulbs. Before you look at the price, get a roll of TP handy. You will need it!

Bioquip sells a small (18W?) DC bulb w/ clips to connect to the car battery. Has a plastic web around the bulb to give some protection. Fits in a small box, thus a suitcase. Use your white T shirt for background.

for some years, it smelled very bad for bulb purchasing and 2 years ago I decided to stock some (and it was not easy to find them). Today it seems very difficult to find any. Some of my friend uses their old (and last) one hoping it will not broken during the trapping or the travel. Arriving of led public lightings rang the end for such bulbs. I suppose the led will offer an alternative (as it seems technically possible) in the future but the actual results are very far from satisfactory.

Incidentally I have been working on a UV LED insect light recently using the work of petermobbs (https://petermobbs.wordpress.com/2015/05/09/a-better-moth-trap-using-leds/) as a template. I have had some pretty good success. I do not know the effective radius of the light I have made but I do know that the three times I have tested it so far it has managed to attract a pretty high quantity of insects (albeit 95% of these have been caddisflies, just hundreds of caddisflies for some reason). While the effective radius is probably not quite as great as the MV or UV tube light from Bioquip, I can make these for considerably less than those would cost to buy and I have built them for maximum collecting convenience: they are built with a USB cord so I can run them off a phone power bank. I have a power bank I bought for $20.00 that I can run it for a night and a half on. I hope to be posting pictures soon both of the light and some photos of its effectiveness. Going forward I am hoping to try experimenting with different wavelength combinations to see if I can target particular groups of insects. To support this I may try selling some of the lights that I know work in the classifieds section. They're inexpensive and not too difficult to make if you have all the components and know or can learn how to solder so if you can't wait till I get around to posting things in the classifieds and want to try this out you can find most everything you need to know to make one yourself in Petermobbs blog. Except the USB thing, that's my own contribution but it's just a matter of using one cord vs another.

It has been several years and I have seen numerous LED bulbs, fixtures containing numerous LED in numerous alignments. Yes, they all produce UV most of it in the 300nm range. They do attract insects. They are not very effective.
I have several samples of LED UV flashlights. I will say one thing, the Chinese are persistent. Yes they work and they will attract insect. However, a 15 watt F15T8-BL or BLB,will out preform everything LED I have seen.
The Pest Control (Fly Traps) companies are attempting to design an LED fly trap. However, they all claim that the Fluorescent Bulb is here to stay, for now.

I just made contact with the distributor. They,will Send me a sample for Leptraps LLC.
I think I understand the concept. But we shall see.

I ran some tests the other night and taken some pictures of the results. As you can see in the picture it at the very least brings in caddisflies. As of the time the pictures were taken the light had been on for two hours.

Well at those prices if I sell mine I would be able to undersell them by quite a bit. Good to know.

I'm looking into the LepiLED light and was wondering if anyone here has tried them out in the meantime. Leptraps, did you ever get around to testing it?
I would be interested to know how it compares to a small 125W MV. (never used blacklights myself)
I have some experience dragging heavy generators and liters of fuel up mountains so this seems very handy if it has decent results. Combine it with a small solar panel/powerbank and you can run it anywhere for as long as you like.

I've run it out of sight of 15w UV bulbs and get the same results, and the bulb runs a lot longer than the 15w. The only caution is that because the bulb runs on less than 12v power it can keep draining a battery. A standard 15w bulb will shut off when the voltage drops too low (still not great for a battery) - this new LED will just down cycle and keep running. You should run the light on a timer or only for select blocks of time to preserve your batteries (I also use deep-cycle batteries to help prevent damage).

Thanks Chris, good advice concerning the batteries.
Can I ask a few additional questions, Which version of the LepiLED do you have? Did it attract a wide range of species? Do you ever use MV light, any comparison?
I never used any low wattage bulbs before (BL/UV), only MV. So I'm just trying to figure out if it would be worth the investment. Portability is a big plus but I'm concerned it has a too small radius as mentioned by other people.
For me the main goal of travelling is often night collecting so it has to be up to the job.
I recenlty heard some great things about it from someone using it in the tropics, he actually prefers it to MV. Benny

I have said this before, LED UV 365 have a narrow light width, similar to Sun Lamps or Spot Lamps. Most of the LED that have used in a Light Trap have a rather short reach of 60 feet or less before the UV Bands begin to diminish. I have a UV meter. At 50 distance from the LED bulb, the effective light is less than 30%.
I am in the process of designing a Light Trap with a LED Lights. These are the same LED bulbs that I currently being tested for use in Fly Traps. The pest control folks were not thrilled with the results.
I must also state that I like a good MV clear bulb. One of the best was a 750 Watt MVSB Clear. However, they had the ability to damage your eyes very quickly if you failed to wear safety glasses.
I have also been told that LED can have the same effect.
My preference is a 40Watt-24 inch 368 QBL Fluorescent. And one other time, Fluorescent are designed for static use. If you travel with your fluorescent bulbs, you should replace the fluorescent bulbs every year, or especially before you go on a collecting trip.
