This light use 2.8A driver to LED, SST-50 die size is small, hotspot will be brighter. Because the die size of SST-90 is bigger, hotspot will be even bigger and a little dimmer too. It will be a total flood light.

1. Low, Mid, High, Strobe & SOS.
2. Low, High, Strobe(2 flash/sec.)
3. Low, Mid, High
4. Low, High
