I have set mine on 700mA in an Aurora C6 host only with a battery voltage of 3.9V. The host will get warm after 10sec.
Freshly charged at 4.14V it gives 1150mA current. :)

I think 800mA is safe in a bigger host than C6. The wavelenght also change with the current to more red. 700-800mA is a good sweetspot.

I got two of these Mitsubishi 300mW closed-can diodes and this weekend ran them at 1100mA in a massive heatsink for a minute just to test. Bright as hell and they suffered no ill effects afterwards. I plan on setting the current at 2 amps and running them in parallel (connected to a FlexModP3) in my RRGB laser projector. I will see how bad the beam is with my PBS cube and decide if I am going to keep them in the projector.

I tried hooking only one up to test and you really don't notice that it is a "line" when it is going through the galvos and the beam is moving so fast. It just looks a bit fat compared to my other lasers in the projector.

if you are still going to be combining them, you might want to just pick up those cheap prisms from surplus shed that cyparagon found. Boom!!

Oh man... I can't wait to get my hands on one of these.

Looks like ~1A is relatively safe for these guys... no?

I have mine running at 1A flat. Burns like there ain't no tomorrow. Highly visible too.

I'd compare the nighttime beam visibility to 50+mW of green (but much worse beam specs, ofcourse).

Nice:drool:

The host you used isn't big... how is it reacting to heat? Do you by any chance have an LPM which logs the data?

I think I found the host for this diode, but the Radiant website is down... Anyone got an idea when it will be back up?

Infinitus - Nope, I don't even have a real LPM, I just have a DIY instrument, I have a 445nm at 1.15 A through Aixiz glass lens, and it measures 1W flat, while that would actually be more like 800mW, so with 20% off while it measures my red at near 600mW, I'd say it's somewhere right about half watt.

I have not observed any ill effects from running the laser for a bit lonber periods of time. Heat can be felt nicely through the host after 15-20 seconds of operation.

ok nice but can i ask how the 635 ( 640 ) can be compared to a green 532 ? what would you say running @ 750mW next to a green 532 100mW or 150 or 200 ? as visibility i think it's like a 100 mw green or is would it be more like a 200 mW green?
