Updated my profile. I help operate a fairly busy night club and also have been testing the Reke-01's (and other units) for the live DJ / Glo bowl at one of the regions busiest Bowling Alley's. Both owned by my family, so I kind of backed into both as a knowledegable novice, but because of crowd...

Did both :-) I also rigged a safety wire on the front of the unit so there's no way it can tilt down; vibration, etc. Covering all the bases. I realize this still doesn't meet the typical FDA 'bru-hah-hah', but again, I have to balance that with business objectives. I'm shooting some videos...

You don't need a gas laser. Constant run diode modules are available for cheap and simply require 12volts. I have many. The problem....is intensity. Anything over 5mW technically runs you afoul of guidelines in the U.S. if people have direct eye exposure to the beams, and even that has...

This brings up an interesting project I'm working on, and it's facinating how it correlates to the OP's question. I have a bunch of cheap Reke-01's, which are inexpensive Chinese servo driven scanners you can get for about $50. They come typically armed with 200mw reds or 30-80mW greens, but go...

Red Solo cups can be cut in half with astonishing speed with a 1watt 445. A two watt will be even more fun. Easily my favorite target for 445s. Just remember to drain the beer first....or boxed wine...depends on how you roll.

It's fun to laugh at the Chinese in some respect on this....as long as you aren't getting screwed on something. :yabbmad:Lets hear it for the good guys as well; ordered some 12mm heat sinks a few days from a Chinese site only to be informed they were out of stock and a suggestion for a different...

The problem is that due to ease in which diodes can be extracted from projectors and such it is next to impossible to restrict import of the things. Some Asian companies won't ship anything over 5mW to the US, but who cares when you get a 1.5watt blue domestically for a bit more money. It would...

I have this debate all the time in LED forums where flashlight geeks are living under the delusion that Cree and Philips have entire divisions devoted towards making better flashlights. I get the same feeling in this thread that laser diode technology is driven by the pointer industry, or...

Good call. My experience with green modules in this price range (usually repairing projectors) is the laser driver and heat-sink really makes life easier if you want to drive from AC/DC. The drivers are usually pretty flexible and will work from 6-12volts, and with the diode being encased...

Ditto. I've learned the hard way with LED's >10watts that the interface between the die and the heat sink is more critical than anything. A clamshell type heatsink puts pressure on most of the cylindrical area of the diode module allowing for a very efficient and large transfer area. Screw types...

The one that came with it.

That's 80mW - I hate auto correct :-) Anyways, a couple months ago I ordered a bare 80mW diode module from E-bay with the intent on replacing a dead one in one of my laser projectors, or just mess with it. I'd have to dig up the link, but it seemed no different than the jillions of other ones...

Wow, ">350lumens" from a 200mW green laser. Somebody call Cree and tell them they suck. I'm lovin that key lock feature though. My grandfather would have killed for that back in the day because when he'd go fishing all his flashlights were dead because we used them to lure bugs and watch bats...

Awesome! Gald I was on the right track. I'll be sure to post pics....

I'm planning on upgrading one or two of my light show projectors from 200mW 650s. These were my oldest units, and while at the time they were pretty cool they just can't keep up visually with my newer 445nm and 532nm units. Fairly easy task swapping out diodes. I'll likely use the Mitsi...

Thanks for not responding to my suggestion - I'm glad you have this all figured out. A bit hypocritical we're referring to the lm317, which is at best a 'ghetto' form of current regulation in terms of efficiency, but then call a thermistor a 'waste of energy'. I suggested the thermistor as a...

Yep. :angel: I was worried nobody would 'get it'. My favorite ones are the arrays rated for 'volts out-put'.

I have several Reke's and other clones running the bi-reds just like above. Mine however aren't even that nice. The reds are mounted in metal cubes about 3/4 on an inch square with no other heat sinking. Doesn't seem to have a problem after a ~hundred hours of running though. I suspect the two...

Hey guys, one thing I use for testing power LED's is a big old thermistor. LED's, especially 3watt Cree's are very sensitive to 'thermal inrush' as constant current supplies initially stabilize. A 700watt, 48volt constant current LED supply is *lethal* to a string of 3watt LEDs if connected...

I'm just glad we're no longer talking about those large, Chinese arrays. Basically they are just stamped boards of 1watt SEMI Led's. Efficiency is horrendous, especially in warmer colors. Maybe like 65watts per lumen at 3500k. The big arrays have problems with heat management as well requiring...
