COUNTRYMAN S9 UV ULTRAVIOLET 365NM 18650 LED FLASHLIGHT

I am a fan of uv lights- I used to use them a lot at work and found that the best by far was the Streamlight Night Com UV. I am however always on the lookout for new UV lights and recently bought two different Convoy lights which are excellent. Browsing through the HKEquipment site recently I noticed that the above light has just arrived ( http://www.hkequipment.net/product-p/cs9uv.htm ). It seems good value for a 5w light. I have bought from HKE many times and have always found them easy to deal with, far better than the BangBest sites. Does anyone know anything about the SVC 5w 365nm? or has anyone heard of the CountryMan brand before? I have ordered one on spec and will report back when it arrives.

If the LED can be overdriven hard with the thermal pad needs to be tested.
On normal specs this one runs at 1400mA, which forward voltage it has is unknown if it is bad it has almost 4V

Radiant flux 960-1300mW @1400mA

The Nichia has 640-1080mW @500mA
and can be driven at 700mA with proper cooling resulting in almost the same UV output at half the current

It is advertised as a 5 watt, 365nm flashlight. I don’t think it is, but measured it is about 20% higher wattage (radiant UVA) than the Convoy. Construction is very similar except they glue the star MCPCB to the heat sink. They also include a fluorescent green “O” ring in the head – probably thought it was cute, it’s not. I threw it away. (although nice indicator that the light was one).

They say they use a CUN66A1B chip from Seoul Viosys – not. The LED they are using is a flat top, the 66A1B chip has a dome. Also, it is not a 5W device. I think they are using a CUN6AF1B part or the CUN6GF1A part and overdriving them hard. I don’t think the little Convoy package can handle the heat a 5w LED would generate.

Side by side with the Convoy it is obviously brighter. But bothers me that the chip is not what they say it is…
