I did a quick experiment without the collar
BLF GT 1610 lux at 80ft
The Sceptre with Synios (no collar) 1170 lux at 80 ft
The Sceptre with XP-G2 S4 2B (old style) (no collar) 1200 lux at 80 ft
So, right now the xp-g2 is winning over the synios. I’ll build up a module with a Flat Black and give it a shot, too.
