3 Pack MP100/U/MED 100 Watt Metal Halide ED17 Bulb, Medium Base, Clear Metal Halide Bulb 100W

These were the exact bulbs I needed. Beware of Home Depot’s, Lowe’s, and other hardware store that carry the metal halide bulbs. They look the same but they are not and won’t screw into the socket because the neck of the bulbs are longer than what the box stores are carrying. The bulb screws into a ceramic socket which is deeper than a standard socket. So the bulb catches maybe one or two threads. The difference is so slight but enough to not work. So I was wrong after trying 3 bulbs from 3 different box stores. Specs were the same as the original but they didn’t work. Found this 3 pack on Amazon and they are exactly what I needed and perfect fit. Box store prices were 25 to 32 dollars for one build that didn’t work. These came as a 3 pack and worked perfectly for the price of 1 bulb. Couldn’t be happier. Work great. Hope this helps everyone when they are looking for a replacement metal halide bulb.

Nice and bright. The precious bulb was several years old and was discontinued by Blink. After searching local stores to no avail, I decided to give these a try. I’m glad I did. Not only do they give off lots of light but you receive three bulbs for a fair price.

This bulb is for my RAB dusk-to-dawn Yardblaster (Barn light) 1. The price: I wasn't really looking to buy more than one bulb, but the price was too good to pass up. When shopping the Internet, I saw single bulbs selling for twice the price of this 3-bulb deal. 2. Fits ceramic sockets: not all bulbs of this type will fit into ceramic sockets. The diameter of the neck of the bulb must be 1.25" to fit, but some bulbs have a neck of 1.5" and they won't fit. 3. Longevity: to be determined. My previous bulb was a Phillips and it lasted 6 yrs. That's 2 to 3 times the rated life. I will try to remember to get back and update this review when the new bulb needs to be replaced. [UPDATE] As of 9-9-2022 it's still working dusk to dawn every day! [UPDATE] 7-12-2023 I replaced the first of the three bulbs. It was still working, but I'd had a couple of times recently when the light did not come on after dark unless I jarred the circuit by opening and closing the garage door. I replaced the sensor, but still had another non-start. Also, the brightness seemed a little low. We'll see what happens. The bulb is rated for 10,000 hours and I got 13,000+ (and it still could be good.)

Good price for 3 bulbs.

These seem to be of good quality and the friend I gave them to said it was a great price, but I did not really understand the info in the description, so be sure you understand what you're buying. They DO give you the info, you just need to understand the terminology.

What I received was great waiting on the rest of my order

Great economical replacement lamps

Terrible - 2 of the 3 bulbs ordered didn’t work.

Très bon
