It should be noted that this thread may be not be heard at Sofirn. After some exchanges with Lan, the MCPCB that was made with XHP50.2s would have been modified 3535 footprints. Too time-consuming and effort.
As noted above, Barry mentions of some prototypes of the Q8 and SP36 with higher output LEDs. Best we second the initiative and voice our interest in the “What type of light would you like the next BLF Special Edition to be?” thread. link
