Is 5000K Warm White?

No. 5000K is a crisp cool white colour. It is brighter and cooler in appearance than a typical 3000K warm white household light, making it a practical choice for work and utility areas.

Will a 1.2m LED Tube Fit My Fluorescent Fitting?

First confirm that your old tube is approximately 1200mm long and uses the T8 G13 format. You must also check the ballast and wiring arrangement.

The GreenLED 4ft tube includes an LED starter for suitable magnetic-ballast fittings. If the existing fitting uses an electronic ballast, the current product instructions require the ballast to be bypassed or removed. Any rewiring must be completed by a licensed electrician.

1.2m vs 1.5m LED Tubes

If your existing tube is about 1500mm long, you need a 5ft model instead. GreenLED offers a standard 5ft 24W 2400-lumen tube and a premium 5ft 30W 3900-lumen tube.
