About Memory-Dimmable Tube Lamps

Revolution Lighting’s Memory-Dimmable Tube Lamp comes in 2-ft and 4-ft lengths. These UL Type-B tubes are ballast-bypass SEP LED tubes, meaning they’re directly wired to the line voltage, with power flowing through a single end (SEP). Because these LED tubes completely eliminate the need for the ballast, there is no additional power drawn (and wasted) through ballast use.


Our Memory-Dimmable Tube Lamp comes in the following configurations:

  • 9W(2-ft), 12W(4-ft), 18W(4-ft)
  • Each available size and wattage comes in 3000K, 3500K, 4000K, and 5000K
  • All are T8 tube lamps and use G13 bi-pins


Energy and Maintenance Savings

Revolution Lighting’s Memory-Dimmable Tube Lamps can decrease energy usage by as much as 50% compared to similar fluorescent tubes. With their 58,000-hour lamp life, these LED tubes last three times longer than fluorescent tubes, so they won’t need to be replaced as often.


Memory-Dimming Feature

The key advantage of our Memory-Dimmable Tube Lamp is that it has a built-in dimming feature that works without a dimmer switch installed. In fact, this lamp won’t even work when there is a dimmer switch installed, and only works with a standard light switch.
Activating the dimming feature is simple. Once turned on, the tube takes about five seconds to reach full brightness. During this warm-up time, you can select the level of light you want. As soon as the brightness has reached the desired level, simply switch off the tube, then switch it back on again. Once back on, the tube remembers the light level it reached when you switched it off.



Revolution Lighting’s Memory-Dimmable Tube Lamp is ideal for offices and commercial buildings, hotels, schools, hospitals, assisted living facilities, and other applications. Revolution Lighting recommends using 4000K for offices, schools and hospitals because this color temperature mimics natural sunlight.
