I had one slung by the lanyard on my sliding glass door handle for years but replaced it with a Jacob A60 ..Seemed more a more appropriate backdoor light..
5600K? That will be nice for tint mixing. :laughing: There are many 12 or 21 or 51 UV led flashlights around where you could change the leds. The 3400K have a great color rendition.
I decided to make a light module out of 28 LEDs in parallel. Hooked it up to a lab bench. Without constant current regulation, any initial current above 840ma (30ma per LEDs) will result in a (very gradual) thermal runaway where the module start to pull more and more current and heat up more until it would presumably burn out. On the first try, I initially set the current at 1.4A, and it rose up to almost 1.6A within 10 minutes.
Granted, these LEDs are packed fairly tightly together and thus complicating the thermal problem. I'd say, if you want to run this LED on a long term, you shouldn't be running this at 35ma (per LED) or more without airflow.
With 840ma starting current, the final current stabilized at 900ma.
Uhh, there are chances that it might slip into tomorrow. Looks like the shipping service has shat the bed and hasn’t called me of the pending delivery and tax yet.
Has anyone measured the diameter? It wasn’t easy to get the LED into the Fenix (fortunately, the E01 has a rubber sealing), and at all refused to fit the Metaminco Bullet. Must be slightly bigger than 5 mm.
