I\'m new to this forum; not new to building lights
Hi all. I'm new to this forum. I was pointed this way by Craig Johnson from http://www.ledmuseum.org
I'm a communications technician by trade, a caver on weekends. (when I'm not cruising the Columbia river in my boat: "Old 'n' Slo) I've built lots of lights in the past, and I'm getting more into LED lights these days.
I probably have no less than 75 lights to date. The commercial lights I have include a Underwater Kinetics UK-1200 and a few little ones such as the UK-120 etc. Streamlight: SL-20, three Stylus three's, and I just bought a Septor. (A 7 LED headlight) A Tektite Expedition 1400. Four (4) Arc AAA's. (can't get my hands on an Arc LS yet) I can't count the Maglights. There's also a 100 watt video light with a 10 lb battery pack for the ultimate caving light. (can't remember who makes that SOB)
I also have a couple of night vision scopes. I like using the 1:1 unit for running the boat at night so I can look for prop-eating "floaters" in the water. (i.e. logs) Radar is next on the wish list, but even that won't pick up a low lying log.
Others lights I've hand built, such as my two-headed monster. That's what everyone else calls it anyway. It's built from 1/16" aluminum sheeting and has two 4" light heads. They're old cop car red/blue units and have 1/4" thick clear Lexan spaced 1" from the special W.W. Grainger lamps. (I removed the red/blue ones) One's a spot, the other is a flood. There's a single white LED fixture in the center which will run for weeks on the 10 AmpHour gelcell mounted inside the 10 lb. unit. It also features a hand crank generator on the side for keeping it alive "forever" in a cave, and also has a charging port in the case for charging from a vehicle. I can post pictures, schematics, and blueprints if anyone is interested in building one. It can be, (and has been) dropped from 5 feet onto it's face with NO damage whatsoever.
I've also built about a dozen "Altoids" white LED lights for friends & relatives. They're built into old Altoid mint candy cans. It uses 4 AA alkaline or lithium batteries, and has three brightness modes. It uses five 45 and five 13 degree LED's in two rows. I'm sending one to Craig Johnson for him to add to the museum collection. I can post schematics for the LED drive circuits if anyone wants to build one.
Thanks for letting my join in!
