Ultra-Bright & Energy Saving: A 140° wide beam angle illuminates larger areas with a brighter light, no shadow or glare. Its a great replacement for a 550W halogen bulb and can cut down over 82% on your electricity bill Efficient Heat Dissipation & Long Lifespan: This brand new series has wider LED chip arrays, which reduce heat concentration, and a fin-type heat sink, which accelerates heat dissipation, thereby giving the flood light a long lifespan of over 50,000 hours
