Rated 5.0 out of 5.0 by Jason If it didn't fit, it's not the right bulb for your fixture
I'm posting this review in response to the previous reviews I saw that mentioned the bulb didn't fit. I'd like to point out that this bulb has a BD-17 base, which means the glass is supposed to taper out slightly at the base. It's not a manufacturing defect, it's by design.
In the cases where folks couldn't get this bulb to fit, that almost certainly means thier fixtures have a ED-17 (exclusionary) socket. The BD-17 base lamps are designed specifically to not fit in ED-17 sockets. The manufacturers do this sort of thing to protect people from themselves. For example, some metal halide lamps can operate vertically or horizontally but not both. Some are designed for enclosed fixtures only, some can't be used in fully enclosed fixtures. Not all MH lamps will work with all MH ballasts. If you match your ballast and fixture specs to your lamp specs, it will fit. If it doesn't fit, it's not the right lamp.
You need to check the ANSI code, voltage, and wattage to make sure your lamp and ballast match. You need to check the base number and globe type to make sure your lamp will physically fit in your fixture.
There's a visual explanation here:

I purchased a 100W Metal Halide Area Light on September 22, 2015 as a security light that I had installed over the outside of my garage on September 29, 2015. Well the light was working find until November 11, 2015 when it stopped working. Now I am having to purchase a replacement. The time in use equates to about 230 hours, when the light bulb is advertised to last 15000 hours.

I bought this bulb to go into my large outdoor light. It appeared identical to the one I removed, however when I tried to screw the new one in it didn't fit. The glass flared out where the glass meets the metal threads, preventing me from screwing it in. The sales associate said that it is a new design and they don't make the ones that do not flare out anymore. I ended up returning it and buying a regular 100watt LED light, and it works great. So beware if you are replacing an old bulb, the old style doesn't exist anymore. Go LED and don't look back..

As others said, the glass at the base of the bulb widens too much to fit in a standard metal halide fixture. I brought my burnt out bulb and was fooled into thinking this was a match, but looking closer at the bulb you can see there is a small difference in diameter that prevents this base from screwing into the socket. Annoying! I thought these things were kept to some type of standard???

Rated 4.0 out of 5.0 by Frank Metal Halide Bulb is a pulse start bulb
Pulse start should be listed in the specifications but it is not. Should only use with pulse start ballast to operate correctly. Packaging does state it is pulse start .

Home Depot asked me to review this purchase. It is a light bulb for a church parking lot. I screwed the bulb in and it lit up. It will burn for a few years(how long- I don't know yet) and then I will replace it again! It is a named brand- Philips
I am happy that HD still stocks some of these "less used" type bulbs and compared to internet prices their price point was good.

Rated 1.0 out of 5.0 by david Although the description says mogul base, the part and product is medium base.
The bulb description and picture both indicate that this has a mogul base. When I received the part, the part number is correct but the base is medium. When I contacted the office they agreed that it should have been mogul. Now I have to find a local Home Depot to return it. I'm a very unhappy camper.
