I bought the 501b and it arrived less than two days later. Exactly as described and burns as expected. Thanks again for the great sale :-)

Re: For sale: NEW 1W-2W 445nm 501B lasers from $110 I'd like to buy one and I've PMed you.

Hey, I PMed you with order information. Please PM me back when you can.

I can get it to a fine point but there's unfocused rings of light around it. The batteries just got low so hopefully that was the problem. They're charging now. I'll upload a picture when they're done.

I'm now using two 14500s in series with an X-Drive at .5A. I was using a test power source before and actually only putting .2A through it (silly me). Now it has the full amount going through it from the batteries. It's much brighter than before but still does not burn anything. Am I maybe not...

Better?

I'll take another picture then. How should I set it up?

Your picture is from a dark room though, mine was in a lit one... If that matters... I always assumed a killed LD would just not turn on at all. Is there any way to know for sure if I need a new one or not?

What's that and what causes it? I got it last week from DTR and have barely used it. Is this what you mean by raw output?

I'm making a box build with the driver set at 480mA which I was told would give me about a 325mW output. I had it all connected and the diode turns on and is not very bright (which is expected for a blue). However, even when focused to a small point, it does not burn. It doesn't even get black...

Yeah, you're right. Thanks.

OK, thanks. I saw this: http://laserpointerforums.com/f44/cheap-safety-glasses-tested-71621.html and instantly fell in love. For $9 on Amazon they're a steal for their performance. Do they have any cheap but good glasses like these for red ones?

OK, thanks for the help :) Is there any way to put more current through the PHR805T without killing it, or no because it's more sensitive than the LPC?

Oh, I'm fine with thousands of hours :p Would aluminum be enough or should I pay Jayrob extra for copper? I wish I could do the same kind of thing and push more current through the PHR805T. Is that at all possible? It looks like I'd get about 300mW out of the LPC with 478mA. Would that beat the...

I don't want to push an LPC too far and shorten it's life too much so idk if I want to put more than 420 through it. I value burning power more than anything else. Would the 405 at 120 mA (about 120 mW) or the LPC at 420 mA (250 mW with AiXiZ glass lense, unless I can boost it without killing it...

I can't afford any of Jayrob's special glass lenses at the moment so I'm going on base mW ratings at this point. Hmm I don't want my diode to day at switch on :p If I could push an LPC-826 to like 450mAh that would be nice. Is 450 really that high for it?

It looks like 120mAh gets 120-125mW. Will it match the burning power of a 250mW LPC-826? I heard from Jayrob that an LPC-826 should be set at 420mAh max for about 250mW with an AiXiZ glass lens. Could I safely push it a bit more without killing it and then have it beat the 120mW 405 if it didn't...

Oh, they can't light an unmarked sharpie? That's a downer, oh well. I like the 405 better. Am I right to say it would be 120mW? I can't find any threads on it or what current to set it at, I'm just going by something I remember from a while ago. Hopefully I'm wrong and it can put out more.

I'm deciding whether or not to do an LPC-826 or PHR805T build. I read that with the way I'd like to do it, the LPC-826 build would push out about 245mW and the PHR805T would push out around 120mW. Since violet is the better color for burning, I'm conflicted because I'm not sure how to compare...

Thank you for your help :) I have experience with lasers and how they work, just not with making them. I am fully aware of their danger to the eyes and have already bought eye protection. I know how to set a driver but am wondering if the one I linked to is as good as a flex drive. Can I use the...
