Spaarlamp Ultron 138115 10W G13 4000K

The Ultron 138115 energy-saving lamp is a 10W linear fluorescent-style LED tube with a G13 fitting that produces 900 lumens of neutral white light at 4000K. Designed for general-purpose illumination, it combines low power consumption with a rated lifetime of 25,000 hours and a wide 120° beam angle to provide even, glare-controlled light in workspaces, corridors, utility areas and retail environments.

Advantages

This 10W lamp delivers a high luminous efficacy for its power class, giving a useful 900 lm output while reducing electricity use compared with older fluorescent tubes. The 4000K color temperature provides neutral white light that supports visual tasks without strong warm or cool bias. The long rated lifetime minimizes maintenance and replacement frequency. The G13 fitting ensures compatibility with fixtures designed for tubular lamps and the broad 120° beam distributes light evenly across a room.

How to use

Install the lamp into a compatible G13 fixture following the fixture manufacturer’s instructions. Ensure power is switched off before replacing the lamp. For reliable operation, use it with ballast or driver types recommended for retrofit LED tubes if replacing fluorescent tubes; where required, bypass existing fluorescent ballasts according to safe wiring practices. Allow a short warm-up period for stable light output after switching on.

Recommendations

Use the lamp in dry, indoor environments and avoid exposure to direct water or extreme temperatures. For consistent color rendering and expected lifetime, operate within the fixture’s specified electrical parameters and replace in accordance with visible dimming or end-of-life indications.
