Here's a nice 520nm 50mW "module" (actually a complete laser in a variation on the "Thor" host) for $38.00. I was able to get mine for only $23.00 because of a coupon code I saw on that page!

Nice find!! I love the "gift" host lol. Not a bad deal at all for a 50mw 520, I wonder if it will be overspec? Where at on the page did you happen to find that coupon code?

It was a special coupon code offered by ePay, right below the "free shipping" and "new condition" boxes. I wasn't able to see it on another ePay account so it may have just been random. :undecided:

Gonna get one of these to check out the host quality, has anyone else made the plunge? I see from the page only 2 were sold so far; 1 on 2 different products.

I have one coming. The host doesn't look like anything special.

Well, it's different from the normal Thor M-II host, as it has 4-fold symmetry rather than 6-fold. I haven't seen it on other eBay lasers.

Looks like that one has already been picked clean. See in the description it says " NO LAMP".

I am looking for the biggest industrial LED's I can get, but these look like fun to play with for 6 dollars. Several could be mounted on a large CU or AL sink, a bit of wasted space around it, the led and driver without the fixture mount should be cheaper by the bunch, if anyone finds raw parts before I do please post, I want to build a monster floodlight.

These look like the 64 watt led streetlights on my road, somewhere is an industrial supply, these are advancing all the time and I want some monster industrial warehouse led's without the 3 phase PS, just the leds.

Holy cow, up to 55,000 LM, if you can believe their specs. I don't take any LED specs on ebay seriously, but could it be that high? Need to research this further.

https://youtu.be/3Pi-LKf0hXIThis video doesn't really give a clear comparison to the 100W, but it does give a sense of an intensity difference between a 100w and 500w (at least the cameras view). IIRC the 100w can give out around 3000- 6500 lumens depending on the chip quality. And I couldn't even imagine what 5x the lumens of my 100w chip would look like at night!
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

I wouldn't expect more than 80lm/W for a device like this, even with good cooling, so 40k lumens on a good day.
