Has anyone had any success using UV LED's?
I've read some interesting papers that rate them as effective as MVL's!
There is lots of waterproof strip UV LED's (398 nm) on the market. I was planning on buying a five meter strip cutting it in half wrapping it around a one inch PVC tube in effect making a replacement for a 18" Black Light tube. Cost is aprox. $5 a tube, no ballast, almost indestructible and would use way less battery power.
I do a lot of remote collecting, only way in is an ATV, dragging in big batteries is a pain. With LED's I could use much smaller batteries.
Am I wasting my time?
Sounds like a dream come true.

There is a person in Germany who sales LED lights for 400Euros a piece, it is a combination of different spectrum lights mounting together.
Let us know if you have some success with your setup. Certainly sound more attractive in regards the cost.

I have attempted to produce an LED collecting light and a light traps. My major issue is effective range of light (The distance that the light travels from the sources) and the expanse or volume of effective light (Large bulbs produce larger quantity of Light). A 15 Watt 18" fluorescent bulb will out preform virtually any LED. Volume and distance. A 15 Watt 28" fluorescent bulb will operate 12 hours with a motorcycle battery. The LED bulbs that have been sent to me by numerous manufactures are light weight, powerful for their small size, use lesscpower and use smaller batteries. As LED's continue to evolve and be developed they increase in strength and size. Eventually they may become the ultimate light source. Until then, use UV Fluorescent and MV bulbs. I have been in the business of designing and producing the equipment that Entomologist, biologists, environmentalists and the amateur collectors to a global market. I understand the how UV and MV light works. Until then, if you like LED's, have at Them. Leptraps LLC www.Leptraps.com

It is a 230 volt light. You will need a converter to use it in the USA.
398 NM is getting awful close to red, Unless the Europeans have another/ different scale.
I also noticed another offer for 250 Watt MVBLB. The bulb is coated internally. I have couple of 160 Watt MVBLB and no one really likes them.

We already discussed this not six months ago do a search

I’m adding 6 new bucket traps to my arsenal. I’m really curious to see how the LED UV strip light works. I bought the 12 volt 60 leds/meter 395nm waterproof type. I got 5 meter lengths and wrapped in around a light pipe. I found a 1inch diameter pipe gave me the perfect length. Things are just starting to warm up here in Saskatchewan, I should be able to post some results in a couple months.😞 Tim

Sorry I didn't realize I was posting such small pictures. From the left: The first one is 5 meters of strip lights wrapped around 3/4 inch diameter pipe. Second is one inch pipe.(perfect for my application) Third, Philips 15w TL-D BLB Forth is 2 12v 40w 320-400 nm 5th, Sylvania 15w 350 Blacklight Last one is Bio Quips 15w BL Most of my traps have easily removable bulbs, so I can carry them in a shock resistant case and drop them in when I get to the collecting location. Another benefit is if my experiment doesn't work, I can easily switch out the duds. Tim

All of these different light sources are meaningless unless you know the spectral distribution of each of the different manufacturers and each of their models and wattage designs. Because it visually appears purple, doesn't mean anything. And 395nm is not the proper or best UV wavelength to utilize to attract or collect insects.

Which IIRC is what Leroy said in the other thread on this topic.
