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.

I really hope they survive at 2a, and while I'm dreaming lets hope this is a safe current for a decent life...

Default Re: Casio 445nm Limits??

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.

We also agreed that no mutation of that name would be used.
