3 Degree NARROW TIR 35mm DIA PMMA 3535 LED Flashlight LENS

Do I lose brightness when using optics?

Optical efficiency is determined by measuring the ratio of light collected after the optic and dividing

by the total amount of light without an optic directly at the LED source. The simple answer is yes.

1, Carclo optics uses a technology called total internal reflection (TIR), so there is light lose during the collimation process.

2, Led Optical Lenses used in the SPOT light, FLOODLIGHT , FLASH LIANG,

city lighting, parking spot lamp, track lighting fixtures, scenery area, retail lighting and other applications where high luminous flux is desired.

Delivery and Shipping:

**LED applications that require more focused light often use a secondary optic that is placed over the

LED, which internally reflects light into a spot, medium spot, wide spot or elliptical spot pattern.

**Most optics are cone shaped and need an optic holder to hold the lens in place over the LED.

The lens itself clips securely into the holder, but the holder does need to be externally adhered.
