Review on F13T5CW Replacement - Get High Watts and Lumens with Ease by Patrice Lippmann

Effective replacement for cool white 13W fluorescent tubes. These LED bulbs are bright, flicker free and use only 9 watts. I'm tired of my old fluorescent bulbs flicker when first turned on as they age. These LEDs should never do this. When installing, note that unlike fluorescent bulbs, these bulbs do not emit a one-sided light (they emit about 330°-335° around the 360 ° tube around).You should mount the dark side on the top of a ceiling light or on the back of a wall light.
