35.0mm Optics/Light Diffusers (Glass/5-Pack)

Pros: 35mm diameter collimator lens fits the following lights: Lowes Task Force 2C 3W Advane Auto Parts Professionals Choice 3W 2C RayOVac Sportsman Xtreme 4W 3C

Cons: Light is VERY spread out, producing a bar shaped pattern. Not what I wanted, but I took a chance. Now I'm using it on the light I keep beside my bed to reduce the intensity of that light.

Other: 5 for $8 isn't a bad price per item if you can use all of them, but I would have rather paid $1.75 for one to discover that I didn't like the effect. Maybe you can use all five in a 6V lantern housing at opposing angles to produce a nice overlapping floody pattern.

Pros: I got them fast. The collimators aren't scratched. They have a large hole so seoul p4 will fit. They produce a smooth line which fades into nothing with almost no artifacts.

Cons: This doesn't throw. The bar will span a whole wall from the middle of a room, and the same led with a reflector seems much brighter. It seems it's less efficient than a reflector.

Other: great for bike lights, but reflectors would be better. I just can't find a reflector with this beam pattern.

Pros: Arrived in individual packing and had no scratches. 35mm optics seems to be able to take better advantage of light sources lumens that the smaller ones (20-23mm).

Cons: Doesn't fit CREE. More precisely beam is good but mechanically it rests on top of the LED.
Beam is a bit to bar shaped for my taste. A more elliptical shape would have been better.

Other: Could be a good optics for a general use bike light (e.g. used mainly in the city). The beam is too spread out for my application.

Pros: Fit perfectly in sku.13741 Gives something like 15x60 degrees oval beam Can be used as bicycle lighting lens

Cons: Has low efficiency (80%, I think) because losses light... You see it if you buy it. But... it still completely useful Item)))

Other: Nice, not cheap, individually-packed, rare and useful. Allows to get great oval-lighted Lamp with combination sku.13741 + 13552 + 44306 (add a coin with heatsink compound between this LED and base of 13741. It will help to fix lens and LED tightly.

Pros: * Oval light output is unique and useful * Fits perfectly in sku.13741

Cons: * Only available in 5-pack, which is bad for people that need only 1 or 2 * Seems to be plastic, not glass as described

Other: If you are already using 35mm optics, then give these a try. You may find some creative uses, too.
