    AA rechargeable batteries - good buy

    I bought 30 of those about a year ago from there. So far I'm still pretty happy with them...and they even forgot to charge me for them!

    Will this light up a flourescent tube?

    Yes, I already have some of the tubes removed from the balast. Seems that the tubes are rated at about 10,000 hours but the balast only lasts for about 100 starts...

    Will this light up a flourescent tube?

    I have a bunch of those compact flourescent bulbs that screw into a regular light socket. (the kind with the spiral shaped tube) Right now I have one in a lantern thing that I made...but the problem is to use it I have to plug it into a power inverter to bring the voltage up to 115v AC. Can...

    5 watt Luxeon questions...

    Yeah yeah yeah...I like to worry! I just thought of something else to ask...if a 5 watt is made from 4 1 watt dies, why is it not 4 watts?

    How do I take the switch out of a mag?

    I have a 2D Mag/EverLED combo that has a little problem. When the bulb holder is moved up and down (as in focusing the head) the light flickers in and out. Probably from when I tested the (non) waterproof abilities and didn't dry it out until a few days later. Anyway, can somebody tell me how...

    5 watt Luxeon questions...

    Is the one watt still at something like 100,000 hours? Why is the 5 watt so low? If I was to find an older 5 watt...maybe in the for sale section here...would that be rated longer? I know I'm being pickey here, but if I'm going to go through the trouble to make something like this (and pay for...

    5 watt Luxeon questions...

    Alright, some of you might want to kill me for saying this, but my main (and brightest) flashlight is a 3D Mag with an EverLED inside, and to tell you the truth I am quite happy with it. Anyway...I'm thinking about doing a full mod on the light and going with a 5 watt. Can I expect it to be 5...

    Removing epoxy from the lens of a SE Luxeon?

    [ QUOTE ] Rothrandir said: you could try flicking it off with a sharp knife, but the flanges of the se are very thin, and looking at them is sometimes enough to bend them i still wonder why everled doesn't make a hd version! [/ QUOTE ] Yeah, I did a group buy on a big bunch of everleds a...

    Removing epoxy from the lens of a SE Luxeon?

    I have an EverLED that has a drop of the expoxy used on the base stuck to the top of the SE Luxeon on top. Anybody know how I can get it off? I would just pick it off but I'm afraid I'm going to break off the top of the luxeon or take a small chunk out of it. The way it is now there is a dark...

    High battery discharge rate - does it do damage?

    I know that if you have a NiMh battery of, say, 2000mah, and you discharge it at about 2 amps, you aren't going to get 2000mah out of it. Is that the only problem with discharging at a high rate? Will it hurt the battery if I was to use maybe 2C?

    Li-Ion Charger IC for $1.66

    Hi's been a while since I've had time to visit this forum. This thing looks like something even I could build - I've been wanting some way to cheaply charge bare lithiums for a while now. There is one thing I am confused about - is this meant only as a charger, or will this also...

    Any free virus software?

    All these recent worms have started to make me worry. Normally, I have a copy of norton that is updated and came with my laptop. I just use it from my laptop to search all the hard drives on my home network for viruses. Well, a few days ago my laptop craped out and I haven't talked to dell about...

    Inexpensive digital current meter suggestions

    I got two meters at Harbor Freight a while ago for like $2.99. Digital and measure up to 10 amps...along with all kinds of other measurements. I'd say they work quite well for 3 bucks.

    Interesting airprt experience with light "arsenal"

    Re: Interesting airprt experience with light So they were just fine with them as soon as you showed them they worked? Just imagine what you could hide inside of even a small flashlight...with a coin cell battery to make it "work".
