Chanzon LED Lens Optical Glass (44mm 60degree) + 50mm Reflector Collimator Houseing + Fixed Bracket with Holder For 20W 30W 50W 80W 100W High Power Light SMD COB Chips Focus 20 50 100 W Watt 60 degree

Great projector lenses, I got large led modules and these throw the light out much better than the chips alone, fit together well and can use a tiny bit of more glue to hold together for projects

Worked great in the classroom for a science experiment.

these make mounting the 100W 9000 lumen LED lites to a heatsink a breeze, and the lens focuses the beam to a very nice circular pattern without shadows and artifacts, also helps protect the face of the LED module too.

Good light dispersing. Needs more options on angle

I didn't pay attention and thought the lens was going to be plastic. My bad for not reading through the product description, it was just a must have for the LED chips I have. Well I was quite pleased to see they're high quality and glass. Definitely glad I made the purchase.

I love this cob lens and this seller.they have any thing for your LED light needs. These cob lenses give your cobs a nice finished look as well as well as increasing you par⭐️⭐️⭐️⭐️⭐️

This lens has a large significant flaw that affects the angle of the beam!! Quality assurance is very low and lacking. This defect should never have been shipped.

Good optical lenses well packed prompt delivery.

Reflector metálico y lente de cristal, buena calidad ya que muchas otras lentes condensadoras que venden son de plástico, no es este el caso. Recomendable.
