21-watt Gen 3 LED corn light is a perfect replacement for Metal-halidale and Sodium-vapour lamps. E27 cap is used for basic and easy installation. This lamp has an output of 2520 lumens and offers a COOL WHITE colour output.
GEN 3 lamps can be used in open and enclosed luminaries, thanks to the aluminium heatsink which is used to disperse heat instead of a fan. This achieves a much better result in terms of average lamp life compared to the previous versions where the fan used to fail causing the lamp to overheat and fail too.
This 21w corn LED is an ideal replacement for;
50w MBFU mercury vapour lamps
160w MLL blended mercury
200w General lamp shade
 
Important information: GEN 3 LED lamps operate directly from the mains supply they do not require any control gear. If your current light source operates using a ballast and ignitor this will need to be bypassed.
