That is a great result. At 3A(which is still within the diode's rated current), It would be about 5w. Dont worry about pushing the diodes too hard yet while they are still expensive. just safe operating current. I think the 3.2a you came up with is a good rating(for now)

For those interested O-like has them for $589 on their site and $599 on feebay. Cheapest I've seen so far.

Some good new!!!!!! Did some more testing on the new 3.5W445nm diode and got 6.39W driver got hot. I do not know if it would have gone higher see video let me know what you think ! 6.39W 445nm from new 9mm diode - YouTube
On the last test batteries were weak.
I have a new Power Supply coming in. this weekend will do more testing and post it

I'm suprised the mirrors didnt melt would be nice to get a micro of before and after... Is there a bond wire count on these?

Holy S^%, 6.39W out of one frickin diode! Thats insane. Just think about it people....nearly 6.5W...out of that TINY little thing! Technology ceases to amaze me!

Sorry crazyspaz, but my inner grammar Nazi makes me say this. You said technology ceases to amaze you, which means technology has stopped to amaze you and doesn't amaze you anymore... :thinking:
Anyways, back on topic. That is just... WOW! Now it's possible for a dual diode build to put out 10W+ :drool:
Can't wait for the price on these to drop.

I cant wait to drop the hammer on one of these builds. still keeping an eye out for a suitable driver and the price to drop.

You know what I meant gosh dangit -_-
ceases to fail to amaze me*
Happy now?

That is very awesome! I saw the video, and I think it would be better to wait until the prices drop on these diodes a bit before pushing them too far; 6.4W from one diode is an absolutely awesome result and I don't wanna see you kill one of your new expensive diodes too early

I was shocked to see the out put ! The diodes is working good :yh: glade I did not blow it! I hope the price comes down too. I hope some one will find the projector that these diodes are in. look at this one it has 87600 hours run time ebay Panasonic PT RZ475U DLP Projector 1080p HDTV 16 9 1920x1080 FHD 20000 1 3000 LM | eBay I would like to buy one and take it apart but $6771 is a lot

Yea I would just worry they are just driving the diodes @ a lower current than the sibling RW330U to get the longer hours rating which has 30 regular 9mm 445nm diodes in it and a higher lumen rating of 3500 compared to the 3000 this claims to have. That would leave you with 30 $250 standard 9mm 445's but lets say best case is 30 of the new 3.5W diodes that would be $225 3.5W diodes.
Here is the block from the RW330U.

That would be bad to have $225 in the old 3w diode and it not be the new 3.5W. Have you seen some projector that look like they could have the new diode them?

How the heck are those diode clusters cooled? Seems like they would all die from heat pretty quick, but then again they are probably fan cooled...

The backplate on which the diodes are mounted is finned or connected to a finned heatsink and then this is fan cooled:beer:
