I just picked up the Rayovac Indestructible Spotlight for $39 at Home Depot. Submersible up to 1 meter (3ft). 15ft Drop test.
500 Lumen - 10hr (360m), 200 Lumen - 18hr (253m), 52 Lumen - 65hr (134m)
If anyone’s interested in some beamshots let me know and ill try tonight
I want to see some tear down pics. I want see the pill and maybe see if it can be modded to hold 18650’s
Unfortunately I’m not qualified to get that in-depth. I apologize.
There is no way in hell it can do 500 lumen for 10 hours, otherwise i think 6AA woudl be great, eneloops are far more durable then li ion
Well dangit I thought Rayovac was reputable. These companies really chap my ass.
I have to agree with Bort, 10 hours at 500 lumens is impossible for the batteries it uses. Way over-rated.
How long would you say is a reasonable runtime on high for this thing?
2.5 hours if the circuit is VERY efficient, but many drivers are low efficiency, i would expect 1-1.5 hours max
well damn for $40 and only getting 1-2hrs this thing is going right back to Home Depot.
Even with the best Eneloop Pros in it, if its a real 500 lumens, i would guess a maximum time of couple hours. I learned long ago not to believe the claims from manufacturers on the packages.
I know but dang that is a DRASTIC claim for them to make. I have no way of measuring lumens but I do have another 520 lumen flashlight. Tonight when it gets dark I will turn this spotlight on and tail stand it… I can check periodically to see how fast it drops.
I am surprised how inflated it is, anyone could measure it easily, and its not from a chinese website, i smell class action lawsuit (maybe i have driven through too many states advertising injury lawyers) :bigsmile:
I assumed it was LED lumens so i checked how many watts it takes, multiplied 2000mA eneloops times 1.2V and divided battery watts by LED watts. I’ve noticed many boost drivers are in the 50-75% efficiency range, this one would be a buck driver (or maybe linear but that would be horrendously inefficient).
I think you will get 1-1.5 hours, though make sure its not getting too hot but still shedding heat otherwise you could burn out hte LED.
This light sounds like its going back regardless now so if the LED burns, let that mofo burn.
Well if Cree states the emitter can produce 1000lm at max rated current under laboratory conditions, and the best cells can produce detectable light on the lowest mode for 50hrs., the the box will say
"Up to 1000lm for up to 50hrs.*"
"*Manufacturer rated"
Edit: used wrong bin
By my calculations using Duracell 2650mA batteries at 90% driver efficiency if you want 10 hours of battery life using an XP-L on sinkpad you would get 310led lumens, expect 225-250 lumens OTF
Thats the highest capacity NiMH i know of, with the most efficient LED available on a no dielectric star.
It has 3 modes, I would bet the 10 hours is the low setting
500 Lumens will pull maybe 1.5-2A those AA batteries won’t keep up for that long
nice little light…a little pricey for me
Just like the big lawsuit against the lawnmower and small engine industry for over-rating the horsepower on their engines, (and they all lost).
why did they lose?
The package shows it as ANSI FL1 Lumens……
So it puts out 500 lumens for 3.2 minutes then drops to 11% for the rest of 10 hours…
That meets ‘ANSI standards’ for output and run time.
