I’m not sure. People have tested the SST-40 version with 30T and GA cells and the output difference was not a lot. I think it is basically maxing out and the more current just goes into heat which reduces output (output goes down as heat goes up). If you look at the output curve of any led it looks like a roller coaster hill (assuming it survives).
So the SST-40 tends to max out around 9A-10A. We can get this without a high drain cell. Even 8A is pretty close to max output.
The 3v 50.2 on the other hand maxes out around 20A-22A. Someone measured about 15A with a VTC5A. I think someone else got 16A. That means there is room for higher output.
The thing limiting the output of the SST-40 might be the forward voltage of the led and how it controls output. I don’t fully understand it. I believe the 50.2 can go higher than 16A. I’m not sure what the highest drain someone has tried on the 50.2 FT03. You might ask on that thread. Maybe someone tried a Golisi or a 30T. I just don’t remember.
JasonWW nailed it. The SST-40 needs only ~9A to reach peak output, while the XHP50.2 can almost double that figure. With a single-cell light like the FT03, the 3V 50.2 will basically take the best cell that you can throw at it.
The SST-40 FT03 gets warm fairly quickly, but the XHP50.2 version is best kept away from children ;). These are very nice value lights, though, and I’ll eventually buy more of them.
Some people would like the switch light to stay on to help locate the switch in the dark even when the light is on.
I don’t find this necessary with the FT03 as I have no trouble finding the switch even with gloves on, but I think I understand why piperasgr might want an always-on switch.
Shady bussiness from BG again…
Freeme, dont do this “we will take you money now and deliver the product one day, maybe” deals.
I know this affiliate business of highly profitable but offering something you don’t have and you dont know when will you have only leads to bad reputation.
P.S. BG points are completely useless, can only be used on undiscounted products which you can find in other shops for far better price without codes. + 50 points is ,50 cents !
500 points would be something meningfull, 50 points is just loughing at you face while they use your money.
Every person has to decide if they want to go through the “Preorder” process. Believe it or not, some people like it, it’s exciting. If you don’t enjoy it, it’s best to wait until it’s in stock and starting to ship. It may cost you a little more and you might get it a bit after everyone else, but at least you won’t be waiting.
Hello all is there still coupons for this light I had one off of google but does not work anymore. Probably will not order until last week of december saving up BG points for even more discount,
You got mail.

It would be nice if Banggood did periodic updates for buyers on factory availability. At least buyers are informed ahead of time. Lessens the frustration level. I think the delayed delivery is kinda expected this time of year. I mean I don’t think Astrolux was expecting such a huge order already. But then again, I ordered some Shockli 25560 Dec 1 from Banggood and it’s still in ‘Processing’
