Re: Want an unusual host built? Just ask Ehgemus - My RGB!
Yea, the 445nm is 2.5 watts of blue and thick, way out of proportion to the lower powered single mode diodes in both power as well as divergence/beam thickness. I will eventually replace it with a single mode 445nm. The 50mw rated 520nm green single mode diode is still holding up without a failure, it is running at close to 100mw, way over a safe output for that diode and without a driver, crazy to do that, but it hasn't failed yet. I don't let it run more than a minute or so at a time though, it's power does creep up as it gets warmer and will fail at some point if I let it run too long, or in time just from the hard switching spike alone, I believe. I've switched the green diode without a driver off and on a few hundred times by now, keeps on playing... fingers crossed. I really do need to order up a couple of modules from DTR and get this thing setup with all single mode diodes with drivers too, been spending my hobby money on other things lately, so on the back burner for now. I'd like to have a host built with three separate heads, one for each color, each mounted on a swivel ball and set screw, that would line them up perfectly parallel.
Also, I need to install some Teflon tape on those lens holder threads too, sometimes the beams get a bit out of parallel if they move just a little bit from vibration. The beams are far more parallel than I thought they would be, with that fix ought to be very close.
Edit: Here's a post on the PL520 single mode diode I found from DTR from 4-20-2013
From this, it seems my diode is acting normal; tough.

On the PL520 murder currently 1A... and it still has not died. It just dims after 750mA and lights back up when the current is turned down like the 445's and the mitsu diodes when too much current is applied. These seem to also be some tough little buggers.
