The Olight Beam Diffuser converts the focused high-output beam of an Olight flashlight to a soft, diffused, wide-angle beam for close-up applications. Also popular for low light applications.

  • The lense of the Olight diffusers are made of ground and frosted glass.
  • Offer a lanyard loop for convenience.
  • The lenses can also be used on the tailcap of all T series lights to make a stable base to stand the light up like a candle - excellent for camping!
  • Inside Diameter: 21.4mm~21.7mm, 25.0mm~25.5mm
  • Outside Diameter: 29mm
  • Length: 18.8mm

The first time I puut this on my light a filter popped out of the sleeve. I had a tough time getting it seated again.
  • Diffusion of light is good
  • I'm concerned the filter will fall out again

Fit is very loose on later model T25

This diffuser is well constructed, using pliable rubber and frosted glass. It is designed to allow some airflow between the rubber and the light so there is minimal impact to air cooling when running on high. All that is great.

The problem is that it BARELY stays on the head of my T25 -- even a slight jostle will knock it off. I suppose I could put a piece of shrink tubing on the head to provide a tighter fit... but I shouldn't have to to that when buying a product made by Olight and supposedly designed to fit their light.

The saving grace here is that it fits another light -- MagLite XL50, and I imagine others in the XL series -- almost perfectly, albeit without the air cooling benefit described above (the XL50 has a bigger head diameter than the T25). So I'm keeping the diffuser because it salvages that other light, -- which was too throwy for my taste, but is now nicely diffused for everyday use.
  • Made from excellent materials, seems relatively sturdy. Works on other lights.
  • Does NOT fit the Olight T25. If needed specifically for that light, this would be a disappointing purchase.

This is a very useful accessory for a T20, T25 I20 or I25. It changes the beam into a soft diffuse light better suited for close in work like looking for some small dropped item or walking around the house or campsite at night when you don\'t need a light that throws a beam a hundred yards. Olight reduced the diameter of the bezel on the T10-T15 and I10-I15 so this diffuser does not fit the newer 2010 versions very well. It is usable but fits loosely and is easy to knock it off of the flashlight and it just does not look like it is for these lights. It fits the 20 and 25 versions and the older 2008 10 and 15 fine.

great little diffuser, well made and gives a good flood beam, doesn\'t stay on the T10 too well, its probably more snug on the T20, but to my surprise, it happens to fit my mag-lite XL100 nicely! very cool, I\'ll keep it there and get something else for the olight :-P

thanks battery junction for the great price and quick ship
