The Red MR16 48 Cluster LED bulb from Prolite is made to replace halogen MR16 bulbs. They will go straight into your previous MR16 halogen fitting and just require a compatible LED driver to be installed. They are ideal for decorative or accent lighting and operate on just 2w meaning that they have a lower energy and heat output. Prolite boosts and average lifetime of 30000 hours and the bulbs have a warranty of 2 years. Please note LED MR16 lamps require drivers of the appropriate voltage to operate and have limited compatibility with existing halogen transformers.
