    tight beam with 7xml possible?

    Hi Dexter I placed a small O-ring under the lens to give the tight spot, I just got back from a diving trip to Norway where we did some 70 meters dives where it was totally dark but in clear water and here the light was perfect we could throw light as long as we could see and we got a large...

    tight beam with 7xml possible?

    Hi The calculation seems high given the spec on the lens says +/- 4 deg., but I am no math genius so you might be right. How is this spread compared to what you have done, I have tried a lot of different setups, I tried reflectors but to get a decent beam I needed to go up to at least a 40mm...

    tight beam with 7xml possible?

    tight beam with 7xml possible?

    Hi I build a dive light with 7 Xml , and I got a tight beam using a lens build for the mc-e led and putting a small o ring under the lens to lift it a little bit above the dei, and that gives a wary tight spot using a 20mm lens, the lenses I found build for the xml is all bigger and I...

    Dive Rite LED Upgrade

    Hi I recently built a dive lamp with 7 XML my problem was that my light head was only 70mm in diameter and I still needed a very tight spot so what I did was to place a small O ring around the dei and then place a LM1-Rs lens from Cutter Electronics on top off the O ring to lift it a couple off...
