    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 ... Read more

The legs on the optics line up ... 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 ... Read more
