6watt LED GU10 bulb

If you have seen my other blogs regarding GU10 & MR16 bulbs , you will know that I now favour LED replacements where possible. It's becoming something of an obsession.

I noticed that the online retailer simplyLED were offering a 6watt(55watt equivalent) LED bulb.

I've purchased from simplyLED before and found their service very good, with a no quibble returns policy. I ordered one to try, which arrived the next day
