Yeah, this is where hand shots are a necessity - from the overall shape, you would never know how large it was!Great review selfbuilt. :twothumbs The photos of the SR90 in your hand are almost comical...that thing is HUGE!!!
Good points - although I suspect they went with such a large reflector because they needed a large thermal mass in the head to act as a heatsink, given the current flow. Probably a bit of a chicken-vs-the-egg issue, I suppose - I'm just glad they went with both in the end (i.e. big heatsink and big reflector).It's big, but then so are HIDs. The SST-90 is a hungry beast, and needs a lot of power. It's also a big LED, so it needs a large reflector.
I agree - great job on both regulation and runtime, at both output levels.i, too, was surprised by the near-perfect flat regulation. olight did a damn great job on this light
I don't know if you are supposed to, but you certainly can. I accidentally left it plugged in for half an hour during a Hi mode runtime , and it added about 14 mins to the total length of the run. A bit surprising that it added so much, given that it takes ~4.5 hours to fully charge the light.Can you use the SR90 while charging?
We hope. Laptop packs have hardly been free of failures.While the M90's performance is stunning, what impresses me most is the power system: by using a laptop-like "smart" battery pack instead of loose cells, we get all the advantages of lithium ion cells, in a manner that's safe enough for the wider consumer market.
As for the Hi output, I look forward to the comments of those with more experience of HIDs. I suspect the SR90, and other SST-90 based lights, will drastically eat into the market of lower wattage HIDs. Please feel free to discuss …
The tailcap is removable, which adds hope to me that separate battery packs may eventually be offered for sale. It would be great to be able to pick up a "spare" cell/handle to carry off with you ...
:laughing:Holy bat, cowman! What a review. What a light.
It certainly does seem like a game changer, doesn't it? We finally have a single LED that has ventured into HID territory. Pardon the pun, but the future does look bright ...Today there is a before and an after in my flashaholic life, now i know that a SR90 certainly will be mine, it's time to order one.
Yes, a good analysis methinks. It some ways it is more the proof of concept here ... I think it will be the subsequent LED advances that really make their mark.The SST-90 in collaboration with Olight have pretty much rendered the 24-26W HID light class obsolete. The only slight advantage that this range of HID's can maintain is in their smaller size since it's not feasible for the SST-90 to run at 10A in a light the size of the Boxer24W. It could be done with IMR cells but the run-time on high would have to be actively regulated to prevent damage. I'm sure the next large format single die LEDs will run cooler and more efficiently allowing LED to overcome this final HID size advantage. 35W HID lights may very well be next on the obsolete list in a couple of years if diode surface brightness keeps increasing.
The spare batteries will be available next week. We actually HAVE them but our webmaster's wife had a baby last week so we're a little behind on these things. They should be available this week.
Thanks for the first-hand experience. Good to know the throw was significant, even if it doesn't seem to live up to the 1000m claim. Realistically, I don't see why you would need that far (unless the light also came with a built-in set of binoculars - now that would be an innovative design! :laughing.while it throws many times better then my aspheric Tiablo A9, it will not throw 1,000 yards, The furthest tree line at Milky’s house is 860 yards away and this light could not make it out that far however it easily made out the trees at 600 yards. Not trying to put it down, but just stating what I perceived. It made my 35 watt Oracle look like a flood light “the SR90 easily beat it in throw too:thumbsup:!”

UPDATE: As HKJ points out, it is not really a reverse clicky - it is a momentary switch that is programmed to turn the light on/off when you release it. As such, there will a small standby current drain, but it is probably insignificant.
