Great review! I have the R50 Seeker and would not consider this an upgrade, unless you just want more lumens. I love the data you produce.
thanks for the review. love the charts, graphs, and pictures.
Impressive results! Crushes the Acebeam in efficiency! Do you own a Klarus G20 by chance, and if so, are you planning on doing a review of it?
Klarus has sent me the G20, but haven’t received it yet.
Great review as always. Now there is pro version, $20 more to get more lumens and efficiency.
Nice, I am waiting for your review on G20.
Anyway, looks like you are now one of the most wanted reviewers 
Using the same Vappower 26650 4200 mAh high drain battery, I measured the runtimes on three lights. The Olight R50 Pro is clearly the most efficient with 9 % more total output than the R50 Seeker and a whopping 27 % more than the Acebeam EC50 Gen II, which also uses the XHP70 emitter like the R50 Pro.
Nice review and Nice light!!!
I am looking my first 26650 light… will be the G20 or this R50?….
Bought this as my first 26650 light but made the mistake of buying a button top batt as spare (Klarus 26650 5000mAh). The batt doesn’t fit in the light. Note to self, do not buy button top batt for this light.
Excellent review … I love my Seeker.
Olight shouldn’t have removed the lanyard hole in the R50 Pro :-).
Great review! I was deciding between the Acebeam and R50 Seeker, and this made it a lot easier. Thanks again.
If you’re particular with the tint, better go with the Acebeam EC50 Gen II.
Great review!
What I like most are the real uncooled runtimes @ real lumens.
They are so different from what’s on the box.
It looks like turbo on flashlights of this format is just a gimmick to inflate numbers on the box. I hate all that stepping down. I want to select an output and expect it to stay at that level for an hour.
1200-1800 seems to be the maximum sustained output for flashlights of this format. Is that right?
While disappointing it’s also educational. There is no use wasting money on flashlights with turbo. That is, in my personal situation…
Exactly. I routinely use a lanyard with my R50 when walking/hiking and can’t imagine how one could be attached to the R50 Pro.
I just finally swapped the XHP70 on the R50 Pro with another one, a 4500K CRI80 3-step Easywhite I got from kiriba-ru.
As I’ve noticed in the past after shaving the dome off with a razor, the result is quite pleasing for an XHP70. Nice creamy white spot at 4123K and not that off white tint of duv 0.0020. The cool/purple spill is also totally gone with just a smallest hint of yellow on the corona.
Those are good numbers you got there maukka (compared to the original measurements you made on the R50 Pro). How did you go about opening the R50 Pro?
Unlike on the small batons that are press fit, the bezel is threaded on the R50 Pro. I used the bottom side of a mouse pad to screw open the bezel.
Is the mcpcb not glued?
No glue, two screws holding down the mcpcb, easy swap.
Maukka, did you also try the XHP50 from kiriba-ru ? I bought one that I put in my R50 but find it quite green…
