    Going crazy finding a 365NM LED flashlight

    Hello, I hope that the craziness didn't prevent you from making a decision. If it did I just did a large post on 365nm that I hope answers your question and those that find this through a search engine...

    365nm 18650 Checklist. Need help.

    Apologies for the lack of response. No one was able to help me so I had long discarded this as a resource for information. However, CPF has helped me in the past so I feel obligated to help the next people in line. I hope this response will be a catch-all to those wanting to make a 365nm...

    Do I need a buck/boost driver?

    Hello, I was wondering if I'd need a buck/boost driver for this dropin. I want to crank it up to 3A but I can't tell if the LEDs are driven in series, in which case I can just get a standard 17mm driver like this. I assume yes but I'd like confirmation since it was an expensive drop in (at least...

    365nm 18650 Checklist. Need help.

    Just for future reference to anyone looking to build a longwave UV light like I did. The LED ENGIN LZ1 is garbage. Far too much visible light. I actually got a green hotspot! That's way above their 365nm range! I had more luck using a 3W 365nm Ultrafire drop-in. Cheaper and put out less than a...

    365nm 18650 Checklist. Need help.

    Thanks for the response. Would a single 18650 work though? The typical forward voltage is 4.1 according to LED ENGIN's spec sheet. Would it dim considerably after a few seconds since a fully charged lipo only has 4.2V? As for the driver it looks like all the UV models Ultrafire makes is driven...

    365nm 18650 Checklist. Need help.

    Hello all, I've never modified a flashlight before so I was hoping that the knowledgeable people of CPF could help me. The goal was to make an 18650 powered 365nm LED flashlight for my fluorescent minerals. As such I need more flood than throw. LED: Likely going to be LED ENGIN's LZ1 (though...
