Review on Discover the Powerful Luminescence of MP100 Metal Halide Medium Clear by Greg Roberts

This lightbulb is for my Dusk Till Dawn RAB Yardblaster (Barn Light)1. Price: I wasn't really planning on buying more than one bulb, but the price was too good to pass up. While shopping online I saw that single bulbs were selling for twice the price of this 3 bulb deal.2. Suitable for ceramic sockets: not all lamps of this type are suitable for ceramic sockets. The neck diameter of the lamp should be 1.25", but some lamps have 1.5" necks and will not fit.3. Durability: to be confirmed. My previous lamp was a Phillips and lasted 6 years. This is 2-3 times longer than the nominal service life. I'll try to remember to come back and update this review when the new bulb needs to be replaced.
