The Osram Ultra-Efficient range of LED light bulbs offers huge energy savings, 60% less energy than other LED bulbs on the market today. With a lamp life of 50,000 hours, this is a fit-and-forget lighting solution expected to last 50 years based on average standard use. 

They are one of the only A-rated LED bulbs available in the UK lighting market today and with packaging made from 100% recycled material making them the most sustainable lighting solutions available.
