LED Fluorescent T8 48" Bulb (15 Watt 240 LEDs) White by Oracle Lighting: Replace those old T8 fluorescent bulbs with new LED bulbs by Oracle. You'll enjoy brighter, whiter light, and best of all, lower power bills! LED is the wave of the present and future. Not only do they take less than half of the power of standard bulbs, they don't have a warm-up period. This means when you turn them on, they're immediately at full brightness. LED T8 bulbs also don't require a ballast, which eliminates one of the most common failure points in T8 light fixtures. Installing these bulbs into an existing fixture will require removing the ballast. Click the "Video Demo" tab above for more information. This is pretty simple to do.
