Can they tell you what wavelength the UV is emitted at? Specifically does it emit at 365nm wavelength which is the best for attracting moths. The wattage is quite low but that could be boosted by using several so is not necessarily an issue but the wavelength is the crucial one

Had a reply, as follows.
There are 3 pairs of leds. Each pair is centred on the wavelengths of 395, 440, 525 nm for UV, blue, and green respectively.
Thoughts?

Those are pretty much spot on. Thanks for finding out

I assume in that case the difference between 395nm and 365nm isn't that much in reality?

I agree I think they are pretty close, and certainly the blue and green are within 5nm of what I have seen quoted as being the ideal

Thanks for this info Stuart.nice to now have these wavelengths aa a comparison with other led moth lights out there.regards

Thanks Stuart,it could probably be fitted to a Skinner type trap though in my experience Skinners don't retain Moths so good.you need some form of cover in inclement weather although it was still on after 2hrs of continuous heavy rain once ! I used a Gemlight at one end of quarry and Podlight nr other end for july/Aug I was targeting 5 specific species Ie Drinker, Confused,Grey Mountain Carpet, Tissue,and a real outsider Northern Rustic I managed 3 of the 5 (interesting though,when a team of us humped a Robinson MV /Generator up there a good few times we never got Tissue and only started getting those to LED,ps didn't get any Northern Rustic or G Mountain Carpet the other 2 target species. I'd say the podlight beats the Gemlight mk 1 on numbers/species, and the only Tissue came to the Podlight.i couldn't tell you the wave lenghts of the LEDs though other than what's been stated on your post.regards Bri. Ps other notable sp were Anomalous ,Neglected and Heath Rustics.

I use all my lights against a sheet or a wall...slight issue with retaining things here as some of the "by catch" can be quite unfriendly.....

Ps Anybody wishing to use LEDs especially the UV ,DONT FORGET to buy some UV protection glasses,they are easily obtainable on ebay etc regards Bri.

 

[Atropos]

Same with MV bulbs as well of course

Yes Atropos,eye protection for MV, MV blended ,and LED, UV/Actinic lights,and probably any other Strong Light Source I should have said Thanks.
