I'm wondering why. MC-E is more flooder than P7...
Off center emitter or die inside? If emitter it's rare - reflector is screwed in in one steady position. But there was many complaints about off-centered parts inside LED and that's Cree's fault.
My M20 has nice slightly yellowish tint with no green hue:
M20 - VB-16 SWO
M20 - RF Spear
Agreed, the issue is not with the assembly of the LED to the mirror, but the position of the die behind the lens. While that may not be Olight's fault, at the end of the day, it is their light. If their supplier is sending them quirky parts, they should work it out with the supplier...
As far as the color goes, the above pictures are dead on for what I see against my white wall. Yellow vs. Yellow Green? who's to say ... It's a warm light.
As far as the MC-E goes, I fired off a note to Allen inquiring about an MC-E pill. I wanted a 'wall of light' for one of my CL1s and for a SF M2. I also asked if he had any plans to do a version of the DB2 with an MC-E. He said he is looking into MC-E drivers and would then look into implementation options once the power supply issue was resolved. Just a guess, but I'm thinking the MC-E over P7 may be more related to power consumption/lumen than throw vs flood...
To your point about flood vs. throw, neither the P7 nor the MC-E are designed for throw, but they can thow quite well, with the right mirror and/or lens.
This Halloween, I took my P7 Mag and my R2 Dereelight trick or treating. The P7 was a lot floodier. It had a bigger hot spot. It also out threw the R2 CL1. Net net, the P7 mag lit up a house a yard, the driveway and the road, while the CL1V4 lit up the front door. Sometimes you want a tight beam. Sometimes you want that tight beam plus flood. The P7 Mag cleared a well lit path for the whole clan stomping down the street. The light screamed "Make a hole. Make it wide" It also had enough throw that I could light up my kids a block away. With all the toys in my light collection. That P7 mag is one of the most useful.
But the P7 mag weighs a ton. I'm hoping that A DBS with an MC-E should be able to yield a similar result in a much smaller, lighter package. That works for me. Lot's of flood augmented by a reasonably tight, long-throwing beam.
