Today had a chat with a new supplier refered to me through a good ebay contact. I have now got suppliers for SMD’s (Surface Mounted Diodes) which are brighter than LED’s and use a similar amount of power. I have 300 GU10 bulbs comming each with 48 SMD’s rated at 2200mcd per SMD, in English it means I have found a direct replacement for bright 50W halogens!
This supplier can also supply B22 candle and bulb light fittings at 200LUX! So hopefully lights are finally sorted once replaced they will not need replacing for around 3-5 years.
