I’m still looking for cheap flooder LEDs. My latest finding is Samsung LM101A….which looks nothing short of awesome.
- very small, 1.15x1.15 mm
- 3V
- fairly cheap, 6-11 cents a piece in bulk
- very high current carrying (for the size) - 450 mA a piece
- CRI up to 90
- 1500+ lm/$ at CRI90
- 4x4 array would be as large as single XHP50.2 but within specs deliver 15% higher output. For half price.
- that’s within specs. Overdriven XHP50.2 will pretty surely outperform LM101A. But the cost is still double.
- very low Vf
- performance scales OK with current - at 450 mA, CRI90 variant is still over 90 lm/W. May still have some overdriving capability.
- 2700-4000K with CRI90, 2200-6500K with CRI80
- available from DigiKey, Arrow, RS Online
