:mecry:Not the performance I was hoping for.
EDIT: Well at least it's Lux, not a true measurement like Lumens, so I suppose there are many variables considering a '4 die' and 'single die' LED shined onto a meter.
I get the SST-50 from PhotonFanatic (first 3 samples he got). I ran the test quickly, thus it may not be correct.
The LED was mounted on a finned heatsink and actively blowing by a fan. It's powered by a 30V5A bench power supply. Testing was at 0.1A step. Current was read from the power supply but voltage is by a DMM across the LED.
It's tested in a quickly made lightbox, no direct light hitting the light sensor. The box surface isn't very reflective. I didn't have a known output light source to compare the actual lumen output.
But from the datasheet:
SST-50 WH-bin:
[email protected]
MC-E K-bin: 370~430@350mA/die (1.4A total)
Testing data of my MC-E @1.4A is 609Lux. SST-50 @1.7A is 596Lux and 1.8A is 622Lux. Assume 1.75A is the average from 1.7A and 1.8A, it's also 609Lux.
I think my MC-E is at the higher range at K-bin but SST-50 is at the bottom of WH-bin.
