These top quality bulbs utilise the latest in LED lighting technology. They are not only ultra-energy saving (only 4W) but they give equivalent light output to 50W halogen bulbs! This new, sleek SMD design uses 20 Epistar LED chips housed in a lightweight casing ensuring the LEDs are kept cool to prolong the life of the bulb. Epistar is one of the major LED producers supplying many hi-tech companies including Samsung with long-life, low energy, robust and highly efficient LEDs for their TVs and other innovative products. When used together, the wide beams of multiple Interlux lights combine, creating a flicker-free, uniform illumination from floor to ceiling for the home and commercial premises alike. With the recent change in legislation now banning the importation and manufacture of the normal 60W incandescent bulb; and the mercury pollution and flicker issues with compact fluorescent bulbs (CFL), these highly efficient LED lights are the natural choice for the preservation of both the planet and the pocket.
