Superior Life brand dimmable LED lay-in troffers are high efficiency alternatives to T8 and T12 linear fluorescent troffers that deliver long life, consistent color and superior lumen maintenance. Constructed of rugged cold-rolled steel, post painted with a highly diffuse white finish. The smooth white reflector curves into the diffuser, creating volumetric illumination by softening and distributing the light evenly in a wide pattern.
Applications - Offices, schools, retail locations and hospitals.
- Die formed of 24 gauge cold rolled steel
- Center basket with diffusing lens provides soft ambient light
- Compatible with today's popular ceiling systems
- Smooth edges for easy handling
- Very low heat generation
- Excellent color consistency and superior lumen maintenance
- Easy installation
- 0-10V dimming - Compatible with Lutron DVSTV-WH and NTSTV-DV-WH, and Legrand/Wattstopper TSD4FBL3PTC and RH4FBL3PTC dimmers
|LED 2X4 DIRECT/INDIRECT-34W/40K/120-277V/Dimmable-SL
A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
The total wattage of fluorescent lamps in a fixture that this fixture replaces.
Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.
|Color Temperature (Kelvin)
Color Temperature (Kelvin)
An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).
A rating of the initial light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.
|Average Rated Life (hr)
Average Rated Life (hr)
A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.
|Operating Temperature (°F)
Operating Temperature (°F)
The ambient temperature in which the product can safely operate.

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
For fixtures and ballasts, width is the measurement of the total horizontal distance from left to right of the product in inches.
For ballasts and fixtures, height is the measurement of total vertical distance from the top of the product to the bottom expressed in inches.
The decorative finish of the item.
