Customers are mixed about the light. Some mention that it diffuses the light widely for use in a wider beam pattern, providing a flooded brightness that exceeds the lights normal. They also say that it provides a pretty even and soft diffused light. However, some customers say that some light reflects downward through the edge of the lens into the eye, creating a bright area above their eyes that is distracting.

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.

4.0 out of 5 stars Great little diffuser for your Fenix light
Reviewed in the United States on April 11, 2011

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.

3.0 out of 5 stars Works, but fits loosely on LD20
Reviewed in the United States on October 24, 2011

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 lens was easy enough to slide onto the flashlight but I had a hard time getting it just right so lid was flush when closed. This leads to some annoying light leaks. i'd be much happier if I was using this on a Fenix headlamp.

The flashlight with lens on wont fit in the stock holster and feels too flimsy to toss in a bag pocket if you only want to use it occaisionally. It's shallow enough to keep in a pants pocket if you really want but again, I'd be worried about it breaking at the hinge where the lid can flip up. I tried this and the red light filter and was dissappionted in both. There is a kit that includes those two, as well as two other accessories for a decent price:  Fenix Accessory Kit - LD and PD Series (4 Piece Kit)  I'd go that direction if you still want to try this out.

5.0 out of 5 stars Candle mode

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.

4.0 out of 5 stars Works as advertised, but not perfect.
Reviewed in the United States on October 18, 2011
Verified Purchase
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 construction

Cons:
- Light leaks from the sides, likely to discomfort your eyes

Ich habe schon lange den weissen Kerzenvorsatz für meine LD10. Die Fresnellscheibe dieses Diffusros hier streut das Licht viel breiter und angenehmer - ähnlich wie bei einer klassischen Taschenlampe. Die Linse ist an einem Plastikring montiert, der auf die Lampe gesteckt wird. Dieser Ring fällt zwar nicht gleich runter, ist aber ziemlich wackelig.

他の方のレビューにもありましたが、本当に黒いものが届きました。
私の用途では、少し大きいので内径につめものして使用。
Diffuserとしてはあまり効果がないですね。

それと、やっぱりふちが白いもののがいいですけどね。
たぶん、透明のふちのものは材質上壊れやすく仕様変更したんだと思います。
ふちの黒いものは、壊れにくい材質に代わっているんじゃないかな？
実際、多少の変形はしてくれます。

送られてきた品がこのページの商品画像と違い、ライトに装着する土台部分が、切れ目の無い黒いリング状の物だった（カスタマー画像参照）。モデルチェンジなどがあったのかどうか、詳しい事は判らない。型番はどちらもAD401 らしいのだが・・・。

土台が透明のタイプはその形状から、多少ライトの直径が違っても許容するので、他社のライトにも流用しやすい。今回送られてきた黒タイプは土台に切れ目がないので、もちろん寸法に厳しい。流用を考えている人は、どちらが送られて来るかショップに問い合わせた方がいいだろう。（私はAmazon の販売する品を購入）

肝心の配光だが、大変ムラのある光で、近くの壁を照らせば幾何学模様を楽しめるほどだった。これは期待外れ。半透明のビニール袋の方がはるかに綺麗に拡散してくれる。拡散用レンズとして作られたにしては、性能は低いと言うしかない。そして減光が思いのほか大きく、このレンズを通すと一気に暗くなる。レンズ部の作り（半球状の突起が多数並んでいる）からは、もう少し明るいかと思っていた。

今回送られてきた黒タイプは、透明レンズのふちが1箇所突起になっており、これを使って開閉する仕組み。しかし、この突起が邪魔で、かばんの中でもどこでも引っかかり、ライトから外れそうになったり、レンズが開いてしまう。もちろん見た目にも野暮ったい。かといって、黒いリング状の土台の 「内側」 にレンズが入ってしまう（土台にレンズのふちが一周覆われる）構造になっているため、この突起がなくなると開閉できないので、切り落とすわけにもいかない。

透明タイプは、土台の “上に” レンズが乗っかる形なので、突起部など不要。よって、引っかかりのない綺麗なデザインとなっている。

全体の質感、プラスチックの形成処理は、今回の品に関しては菓子のおまけ程度。間違ってもFENIX のライト相応の仕上がりを期待してはいけない。134円（注文時）という値段から考えれば、まあこんなものだろう。金属のピンが入った蝶番に関しては、信頼性がありそうだ。

実は、今回2個同時に注文したのだが、在庫の関係で2個目は今のところ発送待ち。後ほど送られてくる品は、このページの画像と同じ品（透明タイプ）であることを願う。

想像するに、リング状の黒タイプの利点は、おそらくライトに固定する力が強い（外れにくい）事、または耐久性だろう。使い方によっては黒タイプの方が良いだろう。切れ目のある透明タイプでは広げたプラスチックが元に戻ろうとする力（バネのような作用）に頼っているので、その点ではリング状の方が有利だろう。どちらを望むにせよ、やはり注文前に確認する事を薦める。

二つ目が送られてきたが、一つ目と同じで土台が黒いタイプだった・・・・。
