Olight R50 Pro Seeker review with measurements (26650, XHP70)

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…

I have tried a couple XHP50s on the normal R50 seeker. CRI80 and CRI90 with different color temps, both of them were pretty bad.

They were from mouser:

Also one from kiriba-ru, which wasn’t good either. Forgot what that was…

edit: it was Xhp50a-0-45g-j20-d0-h-01

Fortunately, the 3 XHP70 that I put in my Olight X7R (also bought them from kiriba-ru) are good enough for CREE LEDs, and you confirmed it here :slight_smile:
I wish Nichia would make big emmitters (5050 and bigger…)

That’s good news. Now I just have to find a nice emitter for the R50 Pro.

I was directed to this forum/thread after asking for advice on another forum.
Having read this review it suggests that the battery will take 1.5 years to drain. Is this with the battery stored in the flashlight and in lockout? Or is that out of the device?
Mine will drain to the point that it won’t operate at all in about 2 months. Olight (and other torch users) have suggested that I twist the cap before storing the torch away (this is what I now do), is this normal? I have a spare (and have tested both) and whichever is in the torch drains and the other will always be usable.

Reading it one year after last message. :slight_smile:
But I get the same issue with completelly depleting battery, when left in the trunk of the car. It was probbaly more then 3 months. So definetely unscrew the endcap. Otherwise charged back up with a total of 5200 mAh.
That is the original battery, still going strong after so many years, and getting over an hour of runtime, on high mode, in real world walking.
Easy and simple user interface. Nice ergonomics, even with gloves on. So a good grandpa light.

Why is this 2016 thread bumped lol

Olight changed a lot since then, huh?

I’m late to the party but recently had to replace my stock battery with an aftermarket because of availability. My R50 Seeker Pro works, but when I toggle through to turbo, I get the flashing power button light. I should also state that I tried to charge the aftermarkets in the light but they wouldn’t charge, I have charged them in the battery charger that came with the batteries.

I assume that my issue is because the batteries are not original equipment, these are 3.7V 5000mAh and not the 4500mAh that came with the light. Probably not good that the light has been discontinued.
