Fenix Diffuser Lens (Fits Specific HP, HL, LD, MC and PD Models)

The Fenix headlamp is so bright that w/out the diffuser it is glare inducing at anything beyond the two lowest settings. The diffuser seemed to be a little too small when I was trying to mount it on the headlamp, but it does fit and is very secure. It does the job it was designed for and seems like it will hold up well.

I purchased this diffuser for my Fenix HP10.It fits just right and basically works as advertised to eliminate the HP10's searing hotspot, providing a pretty even and soft diffused light. The main downside is that they don't provide any frame/border on the diffuser plastic lens, so the light leaks quite a bit to the sides. If you wear your headlamp right on your forehead (without caps), then you'll likely get a decent amount of light in your eyes to cause discomfort... and people around you may think that your face is a floating mini-moon.Pros:- Cheap- Works as advertised in diffusing bright Fenix lights- Light- Fairly sturdy for its small size, cost and simple constructionCons:- Light leaks from the sides, likely to discomfort your eyes

this is the 2nd diffuser lens ive had. the first one was "ok". the one i received this time does not stay open or closed, just flops around, i had to use pvc glue to get it to stay closed, so now when i want to use my light with no lens i have to remove the lens. very cheapley made. they should take a lesson from the "LED Lenser H7" made by Coast and make an adjustable type diffuser. Step your game up Fenix!

What you see is exactly what you get. THE BAD: Problem with this diffuser is that it is designed to fit lights of varying diameters. So it doesn't fit as snug as I would like it to. Easily slides down or off and spins. When you want to close the cap to work the diffuser part, you have to slide it up to the top to line up. I imagine it would fall right off if it was tossed around. Or if you swung the flashlight around lightly. THE GOOD: It's super light, seems durable and fits in the holster while on the light. Just flip of your thumb and you can diffuse the light without having to carry a separate attachment. Thinking about adding a small O-ring on the bottom to keep it firmly in place.

The diffuser does a good job of spreading the light, but it doesn't attach securely. This would be fine in a tent or in the house, where you can find it when it falls off, but it totally fails at any outdoor use, which is what I bought it for. Don't waste your money on this.

Favorite feature: The fact that it actually reflects light to the sides and behind it giving everything a little direct light except what's directly behind it.I bought this expecting something that would give me just a bit more of a flood when using outside and not needing such a fine beam on my pd30 r4. Although the it doesn't perfectly and smoothly disperse light in all directions, it does manage to spread it far beyond the 180 degrees i considered might be the limit. In it's design it refracts light directly to the sides and reflects some behind the flashlight too lighting everything in the area, especially in higher power from the flashlight. However while doing that, it does still provide a flooded brightness that exceeds the lights normal flood zone by a large margin and is brighter throughout.It was rather tough to fix to the head, but has been no problem at all to keep affixed while keeping the flashlight secured in it's stock holster, allowing me to simply velcro the securing strap over the top of the diffuser keeping it on at all times with no issues whatsoever.The opening feature is really nice as well. One flip of the lid and it's back to being a 200 foot spot light.This simple and cheap add-on has increased the versatility of my light more than i can measure for such a small expense.

I use this on my Fenix headlamp and it works well. I was surprised at the level of focus of Fenix's lights. Since I use my headlamps for doing things in large spaces -- exploring, caving, cooking outside -- I have more of a need for "flood" than "spot." This diffuses surprisingly well, lighting up whatever and wherever I am in a broad flood pattern.Other reviewers mentioned that there is a small gap between the lens that deflects light down toward the wearer's eyes. This is correct (and one of the reasons that it gets 4 stars), but it's easily remedied by moving the hinge to the left or right instead of opening it vertically.It also works great for protecting your lens. This is especially helpful for people like me who carry their lights with them in bags and such.Overall, this works well enough, especially for its price. And since it's so cheap, it'd be handy to have on hand and use as a lens protector -- even if you don't find yourself needing floodlight-type throw very often. Just buy it, it's worth the money.

Its supposed to be a diffuser lens for the Fenix HP11 headlamp I ordered...but a) the HP11 already comes with a diffuser and b) this diffuser is way too small. While I'm sure I have other LED's I can use it on, it was aggravating to be misled about whether the HP11 came with a diffuser such that Amazon encouraged a minimum purchase order to get this one.
