REFLECTOR AND LENS
- Triple XHP50
- or Quad XPL
EMITTERS AND MCPCB
- I would choose 3 XHP50 over 6 XPLs, because the reflectors with 6 have a relative small reflective area due to the neighbor cutouts
- Option to get 3 CRI90 XHP50
- MCPCB designed dual footprint with XHP50 thermal pad non conductive (1206 Resistor pad bridge for example)
DRIVER
- 2S/2P Boost for 3 XHP35/50 12V
USER INTERFACE
- from Off short click last memorized mode or first mode of mode order if disabled
- long click from Off Moonlight, remove c) hold 1 second to get a memorized mode
- 4 clicks from on as well lock out
- Option to Moonlight with down to 0.1 lumens in ramping
- option to enable disable memory
- in modes an option to enable/disable moonlight and change mode order
- 3 short presses for strobe advance with long click to beacon and battery blink out, normal click to last mode
THERMAL STEPDOWN
- if this is not calibrated and based on MCUs spread this will be not good, some will be too high others too low,
I calibrated a hundred Narsil drivers and the spread is +10°C/-15°C sometimes even 20°C
- get this with a external NTC on the MCPCB and raise temp to 80°C
- the thermal step-down should use a slow dimming down instead hard step-down’s
OTHER ASPECTS
Put me down for testing and review
I will even prefer a early pre production sample
