Best price on SR51 is going to be Banggood…
Be sure and specify in the selection and PP notes the 18650 battery carrier if you decide to jump for it. They messed up and sent the CR123 holder with mine and several other members, but oh well.
It may be more than you want to spend, but it’s hard to say enough good about this light. You get a wicked tight hotspot with frosted reflector, resulting in a narrow - but very floody - beam. I can light up houses that my STL-V2 has trouble reaching, and with a much whiter (read: not purple-ish) colored light, unlike with the old T6’s. I got an hour and 20 minutes of runtime on two Orbtronics…totally steady brightness and considerably low heat to the hand. I finally just ended the test because there was no point in keeping going. Next to a Tom E modded “super toy” hotrodder light, this is going to give you the best brightness, best regulation, best bang for your buck all-round (they used to be really expensive, but these come with cardboard box to save money, but with the holster, etc), and a UI to die for.
This light has become my most played with light, mainly, because of the UI and the low, which is a usable 326 lumens of no PWM and an 11-hour runtime. I use it for a nightlight (as I’m doing now). Occasionally, I’ll kick into high against the wall just to remind myself of how badly it hurts the retinas! lol I get 1,174 lumens to start, dropping to 1,078 after 5 minutes, where it STAYS for the whole dang rest of the runtime! Amazing! A very close second in brightness would be the XINTD X3, with 1,113 to start. It also maintains brightness wonderfully well.
So yeah, the build quality will FAR exceed what you are used to in the budget realm. Just sayin’.
Now, if you want a cheaper, straight-up thrower with my approval, you can opt for the HD2010 from Willbuying with XM-L2 T6…

Now a lot of these run-of-the-mill HD2010s suck; varying build quality, unknown emitter types, flickering, etc. I’ve trashed them openly lots of times, but these ones are much better built. Read my review at their site of it. Has higher lux than I estimated at the time of the review. Will outthrow anything, I believe, and is around 990 lumens at start (I got only 873 lumens for the Y3). This throws…furociusly! Honestly, it’s that impressive. I recommend it hands-down.
Only thing that could be called a negative is that the more neutral L2 T6 tint can appear greenish on certain backgrounds, but I carry it out regularly just to put spots on buildings at 600+ meters, and it does so very easily. In straight throw, it will take just about anything I’ve played with (except for the larger-headed Maxtochs). I bought this for a buddy and he lost interest, so I claimed it (and I’m glad I did!) The Y3 and this light throw very closely in overall distance, but they are different beams altogether, and if I had to pick a winner, I’d say the advantage clearly goes to the HD2010. The beam is just thicker and wider, but remains culminated at downright silly distances, making it more useful to me. I’ve had plenty of time to evaluate them and there is no denying that this 2010 beam just keeps on stretching out and out further. I still crack a smile when I fire it up!
