FW1A with a XHP50.2 feeler list

M4D_M4X · 2019-09-22T21:00:45.000Z

Hello my dear friends!

Maybe you did not find a FW3A variant that fits your needs?
Maybe you just want them all??

Soooooo:
Here is a feeler with the chance, that your wish could be reality…

I’d buy one but in titanium just because lol.

An uglier beam and worse tint vs basically any of the options available for the FW3X, I’ll pass. Doubt it would out-throw the XPL HI or SST-20 even with a reflector.

Interested just cause I want them all. PM me if it happens.

jmd4tide · 2019-09-23T02:00:40.000Z

I want them all! (I know it’s a problem.)

Di_Joker · 2019-09-23T04:30:58.000Z

I love XHP50/70, I will make frosted glass for it and it will be perfect!
But I would prefer in a classic body Lumintop.

Nice, please PM me when its alive!

XHP50.2 in 21700 + OP reflector with copper pill + without trit holes so head’s wall could be thinner
This is my idea

What are the pro’s and cons of an XHP50.2 versus the existing options ?

M4D_M4X · 2019-09-23T08:05:56.000Z

not as bright but tighter as the FW3A i think
but not as tight (but brighter) ad the XP-L HI in the first FW1A

The main and decisive advantage of the XHP50/70 is that it is noticeably less heated and long runtime.
You can shine for a long time 1000Lm without stepdowns until you run out of battery and your hand burns.
According to my rough estimates, one XHP50/70 is comparable as 7-9 3535LED in modes up to 1000Lm. And in turbo XHP50 it is comparable as a triple, in turbo XHP70 is comparable as a quadruple.
If you do not like the light of the reflector compared to the TIR-optics of the triple, then you can replace the transparent glass with frosted glass or use a frosted film for lamination. It will turn out a very flood light.

One XHP50.2@1Amp have 1055 T_A lm output, 183 lm/W: Testing a Cree XHP50.2 J4 3A led
Four LH351D (@0.5Amp each) have 1124 T_A lm output, 198 lm/W: Samsung LH351D 5000k LED output test by Texas_Ace - Amazing output, low thermal resistance but high Vf

Wow, that’s quite a huge difference in efficiency. I only have 1 XHP50.2 light, a Zebralight SC600w IV Plus, and I really like that it generates relatively little heat at similar outputs to the XHP35 Zebras I own. The tint shift of it isn’t great, though, but with a frosted lens you wouldn’t notice.

Though I’m not a fan of the quality issues the FW3A’s have experienced, a FW1A with the XHP50.2 does sound intriguing, if for no other reason than a boost in efficiency and longer run-times at high output.

I don’t understand the desire to put every light in a 21700 body, especially pocket-lights. It turns a small pocket light into an awkwardly large light in your pocket. Completely goes against the purpose of the FWXX. You get a modest increase in capacity over an 18650, but no where near enough to justify the decrease in usability as an EDC.

I totally understand for larger lights, like a thrower or a light meant to be hand-held on a walk. But small lights? I don’t get it.

This is interesting data.
As a user, I proceed from the real temperature behavior of flashlights. I do not like to burn my hands, and I have to shine long and brightly. Most often I use a brightness of about 1000 lumens and collected some data. From these data, I concluded that the XHP50 in 1000-1200 lumens has serious advantages:
Air temperature 24°C, without cooling.
Sofirt C8F 3*XP-L(990Lm) – 58°C 20 minutes later. And (650Lm) 50°C 20 minutes later.
Sofirt SP33 1*XHP50.2(1000Lm) – 41°C 20 minutes later and 47°C 60 minutes later.
BLF Q8 4*XP-L(~1100Lm “Group6-Mid2”) – 47°C 20 minutes later.
YLP G180 9*XP-G2 (800Lm) 45°C 60 minutes later. And (1400Lm) 69°C 60 minutes later.
Wowtac A5 1*XHP70.2(1800Lm) – 58°C 20 minutes later.
Eagtac DX3B Clicky 1*XHP50.2(850Lm) – 47°C 20 minutes later.

I tested LH351D only the HI-СRI 4000K version and these flashlights were heated in about the same way XP-L 5000K.

It would be very hard for the XHP50.2 to be as efficient as 7-9 35x35 emitters considering it’s basically 4 XP-G3s on one pad.
