    Quality is much better, than I was expecting for this price. Fits with cree xte on 20mm base. As it's made of plastic - it's very light, and can be easily glued to diode base. There is nothing much to say - it's doing job perfectly. Packing is not very good - just simple cornet. One out of 30 had a small defect. Description didn't had height of item,... Read more

The legs on the optics line up nicely on the star, and some small screws will attach ... Read more

    I used this to mod a sadly weak 3x5mm LED Cateye HL-EL100. This optic is remarkably small and fits perfectly inside the body. The beam is good for a bike light, meaning it's a wide spot. I measured the spot to be about 15 degrees wide, and the spill to be about 40 degrees wide. The beam is clean and doesn't have any dark rings. The holder fits perfectly ... Read more

    Cheap reflectors that are small enough to fix several in a tight spot. You can pry off the white housing. Same reflectors as the tri-Led reflectors. There seems to be wasted light that comes out of the side even with the white housing. This is good for my projects building several 3 sscP4 3D flashlights. These reflectors are decent because of the price ... Read more
