The Satco S8979 PAR38 flood lamp is a low energy bulb that's equivalent to a 90-watt halogen bulb while only using 17-watts. The 40-degree beam gives a directed but uniform light that's perfect for display or accent lighting, or for down or recessed lighting. It's perfect for both commercial and residential applications. The PAR38 shape and E26 base means it can easily replace current bulbs without any modifications. With a 25,000-hour lifetime, the 1,210 lumens beam out at a stark white temperature of 5000K. This means at an equivalent brilliance, the Satco S8979 will outlast any other equivalent incandescent.
