Philips MASTER LEDtube integrates a LED light source with a frosted cover design into the traditional linear fluorescent form factor. The new light source offers natural light colors while consumes 22W system energy when used to replace a TL-D 36W with electromagnetic ballast, resulting in up to 50% energy saving. The product’s long lifetime and excellent lumen maintenance minimize the hassle of re-lamping while reducing maintenance costs. A complete range is available to replace 600, 900, 1200 and 1500 mm TL-D tubes.
