reflectors: vLsL-refL01

Aluminum alloy reflectors are provided to enable you to control the viewing angles and the pattern of illumination. As shown

below, without reflectors the viewing angle is 120°. This viewing angle can be tightened to 55° with the use of the reflectors.

Five reflectors are provided with each kit.

With reflectors, pattern is 55º x 120º oval

Without reflectors, pattern is ~120º cone

Lighting panel: vLsL30 and vLsL31

The fully populated LED lighting panel included in each kit

consists of 4 strings of 6 LEDs mounted on a single-sided,

single-layer, copper-based PCB. A shiny white surface

provides a small degree of reflectivity of incident light. The

copper surface helps conduct heat away from the LEDs. Two

lighting panels are available. The cool white panel features

Vishay’s VLMW711U2U3XV high bright white LEDs with color

temperatures from 5000 K to 7000 K and has luminous flux

of 2160 lumens. The neutral white panel features Vishay’s

VLMW711T3U2US LEDs with color temperatures from

3800 K to 5000 K and has luminous flux of 1900 lumens.
