Q: What are the advantages of the Clear Lens?

• Lower cost to produce and work great with Fluorescent or LED tubes.
• Achieves the highest level of lumens and efficiency from the fixture.
• Most efficient. Works well with frosted LED tube lamps but not LED boards due to glare, no hindrance in light output.

Q: What are the advantages of the Frosted Lens?

• Has fantastic hiding capabilities for LED diodes with only losing a small percentage of light transmission.
• Achieves the highest level of lumens and efficiency from your fixture without seeing the full intensity of the diodes.
• SLP’s FR50 produces only about 3 to 5% less light output than our clear blend in Acrylic while still providing great hiding power of raw LED Chip used in the current LED Boards.

Q: What applications do each lens fit best in?

Put simply LED tubes for clear lens vs. LED boards for FR50 Lens.

• Clear lenses are best suited when mounting in higher applications such as warehouses or some food applications.
• Clear lenses would be most suitable in high bay applications of 20’+ and/or applications where the fixture is pointing away from the floor (ie wall wash, awnings, 45°).
• Clear – high into ceilings where diffusion is not needed or desired, also florescent tubes and LED Frosted Tubes
• Frosted lenses are best suited when mounting in lower applications such as parking garages, freezers, and retail.
• Frosted lenses would be best suited where glare (from the diodes) is a concern. For example, applications of 20’ and less from the floor (ie parking garage, low bay food processing)
• Frosted – lower applications where you need to hide the lights or diodes.
