Home / LED Bulbs / Bulbs by Fitting / E27 Bulb (Large Screw) LED Product Description Key Features 14W = 100W Dimmable Warm light 1521 Lumens Product Type: Classic Globe (GLS) Warranty: 3 Years CE / RoHS: Yes Until recently it has been difficult to find a E27 LED bulb that is bright enough to replace the traditional 100W filament lamp (Srew fitting) with a similar light output. To meet the demand, Integral initially launched a retro-fit 16W LED bulb. Due to recent advancements in technology further efficiencies have be achived to reduce the power even further to 14W LED at still deliver a massive 1521 lumens which is more than adequete to match a traditional halogen or tungsten 100W bulb. This delivers the required light output but with the massive advantages of LED technology including 86% less energy consumption - 86 less Watts (when compared to filament), in addition there is no warm up time like energy savers as LED technology is instant on. Maintenance is reduced due to lifetime of up to 25000 hours which is approximately 12X longer than traditional lamps which had a lifespan of 2000 hours. Important Please Note - Dimmer Switch Compatibility Although the dimmable LED bulbs may be compatible with some existing dimmers it is recommended to avoid any flickers that a specialized “Trailing edge” dimmer switch that reduces the current flow to zero is used to also give the full dimmable range. Normal dimmer switches are leading edge and have a minimum load of 50 Watts that means to dim the bulbs fully more than 4 bulbs would be required due to the low power consumption.
