TRACKING WITH CLOSEUPS: LED Lamps from Dubai: They Leave the West Behind
Only sold in Dubai: Philips LED lamps that use more LED chips running at lower current, resulting in greater efficiency (light output per electrical power consumed) and much longer life. The initial cost is higher, but the longer life will probably more than recover this. There's an internal voltage regulator which keeps the lamps from dimming or brightening when the mains voltage varies (but means they won't work with dimmers).
