Do you have a link for a recommendation on a 3rd cell for this light?

Yes we do. But don't think we can post the url here as it is outside of Amazon. But, please allow us to offer some guidance. There are TWO OPTIONS to extend working time on a single charge of the cells. 1) Add third cell using the supplied extension barrel, or 2) Use higher capacity (mAh) 18650 cells, for example 3200mAH cells will give you around 5-6+ hours of working time. HOWEVER, you will see examples which say 9000mAh. The highest known capacities at the time of this writing is near 3400mAh. Anything beyond that should be examined closely as these are often inflated figures. It is better (although not mandatory) to go for good manufacturers such as Panasonic, LG, Sony, Samsung, and the like. Also, a very quick check on any examples you have is to weigh them. If any one cell is below 40 grams in weight then this indicates poor internal cell chemistry. Hope this helps. [uvBeast]

What’s the difference between this leds uv and nitchi uv (both 365 nm)?

Maybe they are from Nichia. Not many manufacturers of 365 LEDs. Makes no difference though. It's real.

Can you check oil leaks in automotive? Engine, transmission fluids etc?

Indeed. Although UV reactive dye will need to be used.

Can I purchase a clear lens separately if I don’t want to run in 365nm?

Hi Nicholas. Thanks for your question. You will always be emitting 365 nanometer wavelength UV even if you fit a clear lens. That's because the LEDs on the V3 365nm emit at 365nm wavelength. If you need a different wavelength then you'll need different LEDs. The only other wavelength LEDs available are at the 385nm and upwards end. Visible light is at around 395nm+. (LEDs also come in the 270nm range btw which is the dangerous UV). Please note that what you can use a 385nm+ UV flashlight for, a 365nm flashlight will also do in the majority of use cases. Hope that helps. [uvBeast]
