In recent years, as part of an effort to regulate mercury-containing consumer products, state governments within the United States have begun passing legislation prohibiting the sale and distribution of linear fluorescent lamps, compact fluorescent lamps, and mercury vapor high-intensity discharge (HID) lamps.

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.
