With the end of the ENERGY STAR rebate incentives to promote ENERGY STAR-certified lamps and luminaires in the marketplace, these products – including several from Keystone – will no longer use the ENERGY STAR name or mark.

Keystone is expanding the range of its ever-reliable PLL by adding more color temperature options to the lamp’s field-adjustable Color Select technology. Keystone PLLs now feature 5 color temperatures: 3000K, 3500K, 4000K, 5000K, and 6500K. To change from one to another, simply click the Color Select switch.

Keystone Technologies, the leader in LED, is expanding the range of its U-bend lamps by adding Power and Color Select to 1-inch and 6-inch models of the UL Type A&B T8 LED tube. These U-bends feature 3 power outputs and 5 color temperatures.

Keystone Technologies has the widest portfolio of LED tubes in the industry. And now, more of them feature the versatility of Color Select. Our UL Type B 12.5W LED T5 HE tubes and 25W LED T5 HO tubes join a portfolio of Type B T8 tubes as color selectable.
