Casio 445nm Limits??

I dont understand how some, that are powered at 1.8A go over 2W, but DTRs bench showed that much lower watt output per milliamp. Can someone explain this?

Is matter of efficence ..... after the threshold value, these chips seem having an efficence superior to the other diodes, around 1,2W/A ..... they simply convert more current in output power .....
 





Oh, I see now! DTR's bench tests don't contradict CD520's build. At 2A it would be close to 2.4W, so over 2W is still in the realm of the tests DTR performed!
 
I am planning on testing 3 builds out at 2 AMP each. I will let you know how many if any survive.
 
It is just like CPU overclocking. Some processors hit 4Ghz with ease and the lesser gods needs a voltage bump to reach the 4Ghz. Not every diodes is the same.
 
I have seen variations from diode to diode. Running @1.5A most will put out 1.6W with a G-1 lens. But I have seen a few only do 1.45W and one or two that did 1.7W @1.5A. It makes you scratch your head sometimes.:D
 
I really hope they survive at 2a, and while I'm dreaming lets hope this is a safe current for a decent life...
 
I wonder about the whole 2 watt idea. By that time you are dissipating 12 watts in a diode package that was originally designed for 1 or 2. Even at normal power levels this is far exceeded, but i think running at 2 amps might be pushing it, even with a huge external heatsink.
 
Didn't we agreed the c@5l0 wasn't used in conjunction with 445nm diodes ?
Just in case. :shhh:
 
Hmm.. drivers get names now that are exclusive to the load connected to them?

/me calls BS
