Sunwayman T25C, 18650 zoomie (edit july4th: mod in post#4)

Yeah, Edmund’s prices are crazy.

Got mine in. Really nice! Measured 864 lumens (@30s), 43 kcd (taken at 5m) stock - really good #'s for a stock zoomie of this size, and about matches what they claimed in lumens of 880.

I posted this in this thread: https://budgetlightforum.com/t/-/42053, but I got mine in from GearBest as noted above, but can't budge the lens retaining ring - using a lot of force with appropriate sized needlenose, all in the CCW (normal) direction. Nothing - not budging... Any ideas?

Just looked at the T25C on GB, £32 or $40 & when you apply the codes it goes up to $53 ?

Yes - reading what it says, LEDFLA coupon expired now, or could be I hit the 1 order limits per coupon.

Still need some advice on opening it up at the retaining ring of the lens.

Update: Got It open!

Weird, but I simply tried the other pair of notches in the bezel, off by 90 degrees, and it came off easy. Really weird...

On mine also, the reflector thing was glued on the threads, but hard to see it's there from the pics:

Here you can see the damage, but should be easy to touch up:

Glad you got it open! I can’t remember if in mine there was any glue on that reflector-ish ring…

(the number to beat is 181 kcd! :smiling_imp: )

It's really a gorgeous zoomie. Just went for a walk past dusk - used my Skilhunt H15 w/Narsil w/nice NW - U3 3D, and a ThorFire BD04 with a dedomed XPL V6 0D, and both worked great, but ended up using the BD04 mostly running Biscotti, 3A. Love flood for the walking in front of you, immediately up ahead, then zoom out to look up the trails, plus the 5 modes worked out great. I'd prefer though a quality zoomie, easy slide like the BD04 but with an e-switch to run Narsil - best of both.

So you’re not bothered by glare from the portholes in the bezel?

o, didn't notice it much. I got the light all apart now, gonna upgrade it.

Hi!

Received the lens I mentioned above:

Smells quality, imho. :THUMBS-UP:

Cheers ^:)

Does it have the correct focal length for the T25C ? It looks like it would be a bit shorter. If it throws ‘quality’ as well, I’m convinced :wink:

11m focal lenght.

No expert in optics but, with that focal lenght, directly captures more than 110° of an emitter's spatial light distribution fully focused (2arctan(r/fl), if I am not mistaken). For emitters like XP-G3 and XHP70's, this means about ≈80.54% of the light gets through the lens (2.93 out of 15.06 units of luminous flux lost).

Or so I think.

Cheers ^:)

11m :open_mouth: , that will be some small hotspot :wink:
