LEDs have proven a useful alternatives to both incandescents and fluorescents when it comes to bulbs with their durability, economy, and promise of better light, but when it comes to tubes, LEDs haven’t quite made the grade. It’s easy enough to shape an LED to match a fluorescent tube, but the color leaves much to be desired and they aren’t as bright as they need to be.
The Cree T8 is a new series of tubes designed to replace conventional fluorescents. According to Cree, the T8 is capable of putting out 2,100 lumens per tube for 21 watts of power, or 3,800 lumens for a two-tube fixture. In part, this is due to the oval shape of the tubes which is designed to avoid wasting light illuminating the inside of the fixture.
