Ohhh, so it stood up to a 30Q without frying. That’s good news. I was afraid you were going to say a Panny B 3400mah or something. Maybe there is something going on with the voltage curves of this new 3-volt version that is making it a bit more robust and resistant to being burned up in a FET driver. I will wait until I see some destructive testing on it before I buy one.
Now if Cree came out with a 3v 70.2 I’d be all over it because those can handle 22A @ 6v. Those are very robust. The 6v 50.2 is a bit fragile.
CRX: If a group buy does come around, and the 3B’s are included, I would change my order to 6 x 3B, (3 on 16mm, 3 on 20mm), and 2 of the cooler ones, (1 on 16mm, the other on 20mm). So that would be a total of 8.
I wasn’t expecting anything. I just wondered because Cutter had them when, from what I can see, no one else here even knew they existed. Tom’s answer summed it up nicely though.
Funny, back in the day here on BLF, 3C was "the" NW tint everyone wanted, but that was basically when we didn't have much choice. 4D and even more, 5D, have been my favorites tint for a long time now, way before I knew what BBL is or meant.
I'm sure Mark isn't getting a choice of tints, I think as he mentioned, just a matter of what CREE has to offer. I'm not happy with the SST-40's in 6500K either, but I bought some and have a few lights using them. To me, a 3B is better than 1A 6500K or 1D 6250K, so I would be more interested in the 3B's. Just a matter of how many to buy.
If VOB gets the 3B's quickly, might just order a couple from him and see what they look like. Right now for the US, it's cheaper to order 6 from VOB, but for 7 or more, cheaper to order from Cutter.
I got a 5X SupFire L1 right now running SST-40's - high output, but with 5 XHP50's in 3B tint, it would be awesome, maybe 20K is possible.
Taped up the UTORCH C8F reflector and going to open up the wire channels in the back of it to clear the jumpers on the triple 3v XHP50.2 board. The reflector emitter holes look to be a perfect fit around the pads should center real nice on the them and will open up the channels enough that IF there is a little clearance ( reflector emitter holes to the emitter pads) I won’t short on the jumpers. Of course I will Kapton tape them any way because of the series pads that are exposed on the face of the board. Also the triple board needs to be filed/champhered a bit smaller on the diameter to fit the C8F shelf, I got it pretty close to seating now.
Wow! Love to see the amp meter reading on that C8F...
The Amutorch X9 is a way better fit though - XM triple now, 26650, hot driver, but I'll still try to fit or sandwich in a custom driver -- gotta take a better look.
Got mine today. Grabbed 6 on 16mm noctigons. Thanks Cutter! I went DHL to the US and got them pretty quick.
Preliminary test yielded 13a (30Q fresh off the charger) at the tail in an s2+ host. I got 3770 turn-on lumens and 3024 at 30 seconds. Host got hotter than pretty much any light I own in that amount of time. 3024 was the reading the second before stepdown.
For comparison, I have a nearly identical s2+ with a warmer 4000k 50.2 in in, running a MTN BST driver. I get 2316 turn-on lumens and 1362 at 30s (thermal throttling of the driver itself)
So from my initial impressions, this is absolutely a hot rod LED if you DD it. I have a few linear l4p 12a drivers inbound and might try it with one of them too, to see what happens.
Now I need to measure current at the emitter. I just wanted to get one mounted up quick to see what would happen.
. Think L4P is the only supplier of one?
