This LED PAR38 reflector shares the same toughened glass body and prismatic lens as the 110W incandescent light bulbs it\'s designed to replace, even though it only requires 13W to produce the same brightness and quality of light. Features a ES-E27 Edison screw (27mm) base/cap.The light bulb\'s body is constructed from a toughened glass shell that protects all of the electronics and internal components from light knocks and abrasions. The light bulb itself is IP65 rated which makes it ideal for a range of domestic and commercial applications both inside and out. The prismatic design of the light bulb\'s lens ensures that light output is distributed evenly within a 30 beam angle. Glare is kept to a minimum, while focus and intensity are increased for cleaner, more effective results. The familiar aesthetics and comparable light output of this LED PAR38 reflector light bulb make it an ideal, albeit far superior replacement for your power hungry incandescent reflectors. It uses a fraction of the energy and lasts upwards of 15,000 hours, which is a huge improvement on the 1,000 hour rating of these older light bulbs. Such a marked improvement in longevity and efficiency can ultimately reduce your lighting bill by up to 90% - all from a light bulb that looks no different to your old ones.Please note that even though the light bulb itself is IP65 rated, it must be used in a suitable IP65 rated socket in order for it to be used outside safely.
