Hey Rich, I just received the 2 x Sharp GH04C05B9G 440nm 5W that I paid 35.00 each for from Chinese ebay seller " sabhz21 " only they were 600mw 520nm diodes which have the same big window apparently, have you received any of these Sharp 5W blues yet ?
No I haven't received them it will be a while with this mess going on over there in comm country.
I have those 600mW 520's bought them a while back and did I few builds for customers. They can be pushed to 900mW's easy, but with all my diodes I put them on a PSU first to see how efficient one from another are. Some can take it and some can't.
On the Sarp Blue I am assuming that to keep it close to 440nm the threshold setting would be ok. But if you wish to achieve 5+ W's thats not the case here. Did one in this host did over 1W a bit dont know how long it will last though.
Yes that was nice build with the extra cooling for the diode and driver the customer also took 2X18650 Panasonics and a charger.
Those 2x26650 and 26500 builds had a brass sink bored out for a DTR 25mm heat sink. They came out nice with the polished brass sink and tail cap. Also had a 19mm latching switch installed ..
If the customer wishes to post the 44 thats totally up to them I dont encourage , but would be nice though.
