Honeycomb Louvers (LVR-SL490-P & LVR-SL460-P) – The spread of the light is controlled by means of thin wall honeycomb louvers. The advantage of these louvers is the minimal loss of light. The Diva-Lite LED fixtures include a 90° louver. A 60° louver is also available as an accessory. They are lightweight and are held to the fixture with Velcro fasteners.
