Spec me an LED Torch

Bit of a review on the Olight S1R now having had it a short while and used it on bike rides etc...

The timed drop from 1000 lumen to 300 and 600 to 300 from both level 1 and 2 is interesting as it doesn't just drop instantly, it fades slowly and you barely notice it drop down. At these brightness levels it gets so hot after 1m 30s that it hurts to touch anywhere close to the head of the torch and even the metal clip starts to act as a heatsink by this point.

You can however immediately take it back up to max brightness if you wanted...

The runtimes for level 4 and 3 are really excellent though, I use these mostly for bike rides and general use. Level 4 is plenty bright to see where I am going and that offers 20 hours of runtime from a 500mAh battery which is kind of insane really with level 3 offering a bit under 4 hours.

The beam profile is much wider than I imagined. It basically is 180 degrees. I can see my shoes if I aim the torch dead ahead in the dark and it's a nice even illumination too no reflector cut-off lines or anything like on other torches. I think this is why the beam profile is so good for even the low brightness modes, Both 12 (level 1) and 60 lumens (level 3) I find to be plenty bright for riding at night and it's actually blinding to point at the eyes.

I have not used the Lumintop Prince (1050 lumens) or SolarForce L2T SS (900 lumens) once yet since getting this as it's so versatile and compact.

I also really like how intuitive the controls are to get to any brightness or mode with long presses, double presses etc and that it has the lockout feature. Battery seems to charge quick too even from my PC's USB ports.

I would definitely get another to keep in the car's emergency kit etc if I didn't have the other two.

Thats the way it should be, brightest torch I have insists on making it as obvious as possible the lumen is dropping by turning off a second if I try to pull too much off the run down battery. Im literally trying to focus on something, really dont appreciate its distraction but also I should carry a spare battery clearly. FT03 maybe I can watch a youtube video and its got an option, I'll post if I find it

ideal setup perhaps just saw this on reddit, when its this bright perhaps also need a dipped beam switch not to blind people :o
  • Acebeam K30-GT SBT90.2 - 5500lm, 1024m throw
  • Astrolux FT02S 4 * SST40 - 7000lm, 639m throw
  • Convoy Z1 W2 - measured at about 1300lm, 121m throw (full flood mode) and 600lm, 950m (full throw mode)

Lets review a torch I got for casual utility ~£20 :)

Supposed to be a searchlight/spotlight out the front, bottom facing floodlight, 10,000mAh battery (doubles as powerpack), 10h charge, 10/30h runtime on main beam high/low and the big claim is... 6000 lumens from a Cree XHP70.2 :eek:

After some tinkering I've decided it's all true.

Except the main LED :D

Clearly can't be a 35W Cree XHP70.2. Found another listing elsewhere by the same brand saying L2 T6 which is a 10W Cree LED, it's not that either.

It's an unremarkable LED fixed to an aluminium cup reflector/heatsink and on a full charge is using 0.69A at 3.36V which would be... 2.3W

Assuming an LED puts out 100 lumens per watt we're looking at around 230 lumens backed up by the four 18650 batteries inside which can easily total the claimed 10,000mAh and that's how it does 10h on max beam and charging it back up by USB is how I spent the next 10h :p

If being generous, modern LEDs can do 150 or more lumens/watt so a high end guess of low 300 lumens.

But there we go, it lasts ages and has the light output of a respectable bike light for town use. Except this is strapped to a big reflector that focuses most of the light into a hard spot and can throw that a hundred metres. Not a good light pattern for close range.

Secondary floodlight of 12 white LEDs underneath has a more useful diffuse light and the design lets you park the torch to use that as a lantern.

Design is chunky and light (530g) for its size, easily room for 2 more 18650 but instead there's foam blocks inside (would make the charge time 15h+ if they were there!). That plus the hollow reflector and handle adds up to a lot of dead space. Comfortable to hold with the offset handle. The stickers on it are terrible and I got them off as soon as it arrived.

Likely to be stashed in a shed miles from anywhere for occasional use.
 
Unilite stuff is really good. ive got 1 for work and proper powerfull
Although saying that i got a a smaller torch from amazon ages ago for roughly £15 and its got the most light output ive seen yet. Will try and find a link
