Cree has introduced a linear LED T8 replacement lamp for fluorescent tubes. The lamp fits into almost any standard fluorescent tube light fixture, both dimmable and non-dimming, depending on the fixture.
The Cree four-foot T8 lamp delivers 2100 lumens of enhanced-spectrum 90 CRI light while consuming 21W for an efficacy of 100 lumens per Watt at the system level. Rather than the traditional round T8 tube style, the lamp has an oval-shaped profile that allows more uplight than usually found in 180-degree LED tube lights.
The lamp is available in neutral (3500K) or cool (4000K) color temperatures. It uses Cree’s TrueWhite technology, which mixes in light from red and unsaturated yellow LEDs to push up its CRI. Cree claims it’s compatible with more than 90 percent of existing fluorescent ballasts. The lamp will sell at $30 each, yielding a payback period of 3 years.
It comes with a 5-year warranty, which is better than the industry standard 3-year warranty, but less than the 10-year warranty Cree offers for its replacement bulbs, downlights, and troffers
