    Awesome! Wife and I are really excited about these. She has a difficult time making decisions, and aux LED color is never an easy one for her. "oooooh that's pretty!".... "but that's pretty, too!" This light solves that problem lol

    Is W1 an option? If itís possible to get 55k lux from 4xW1 LEDs, count me in! W1 should mean less heat, longer run time, better throw. Iím here for it!

    FW3A vs D4 V2 beamshot GIF comparisons in W1 and W2 variants would be awesome... just sayin haha. I know youíre busy.

    Thanks for everything Vinh! Neat little light this one will be, thatís for sure!

    Can you give the model # of what you call the "stock" and "throwy" optics?
    Maybe I am mistaken but I thought the stock optic (10622) was more throwy than the optional frosted 10623.

    anyone else find the aux LED demo not working?

    I've been out of the loop for a while. What LEDs are white1 or white2? I saw the factory link and they seem to have a very bright SST-20 with high CRI which seemed very interesting.

    How do the given options compare to this?

    Also I see you have an optics swap, have you tried dedoming for yet more throw?

    Might be interested in at least 2 of these. Thanks!

    They are great emitters for throw as they have very small surface area but very high surface brightness. More formally known as OSRAM CSLNM1.TG 1mm, CSLPM1.TG 2mm, CULNM1.TG 1mm. Colloquially often "White Flats", or the White 1mm^2 and White 2mm^2.

    They are a good bit different than the HCRI SST emitters. They are betwwen 5500K and 6500K, and about 70 CRI IIRC. The White 1 is about just under twice as throwy while being roughly the same output. The White 2 is about 1.5x as throwy, but higher output by about 25%.

    The white flats are already domeless.

    Interesting. I saw Vinh adding white1 also. Hm gotta decide which I need.

    I currently use a LD60vn as my main bigger light, but I'm thinking of replacing it with this guy and just EDCing it. Near 4k lumens when I need them for a short time, near the same throw, but much smaller for the low brightness every day use.

    My current batteries are INR LGs rated for ten amps, is this enough?

    I think the D4 is a great little light. The only problem that I run into occasionally is that when I EDC, it turns on in my pocket. Because of this, I think the FW3 makes a better EDC light and it has softer edges.

    10A is max for the W1 and W2 and 219b. Any unprotected cell is fine with other LEDs.
