UB lamps by TCPi

Notes for bulbs with Z#s 1--6: These are all from the SpringLamp series by TCPi

(Technical Consumer Products Inc.).
The Energy Star listing for these bulbs can be verified by looking for the product numbers UB14, UB20, and UB27 in the most recent Energy Star List

. The UB14, UB20 and UB23 were lead items in Massachusetts' statewide Lighting and Energy Efficient Products “Big Buy” (PDF

).
All bulbs in the SpringLamp series have a CRI color rendering index of 82 out of 100. This measures how even the colors are from the bulb. An incandescent bulb (warm white or soft white) gets a 100. Fluorescents score about 84 at best, but anything over 80 is considered good enough that few will notice any difference from an normal incandescent bulb.
