Lighting by Westinghouse is in fact commercial lighting and not standard so I’ve no way of testing them. They come individually wrapped separately in its own box and is made of a really thick glass. Commercial outdoor lighting

These are great! They arrived quickly and well packaged. I did buy a converter for the adapter so that I could use them in my standard adapter in the garage. It was hard to see in the garage before, but now it is very well lit and makes it very easy to see! Highly recommend!

These bulbs are very bright and versatile. We are very impressed by the quality. They are pretty industrial and require an adapter for a regular socket. We’ll be using these for our basement. They came well packaged.

Excellent, super bright bulbs. These serve a dual purpose, they fit commercial HID fixtures with the larger E39 socket, as well as being able to be used in SOME normal regular home light bulb sockets with an adapter (not included). When replacing high pressure sodium/metal halide HID bulbs, the ballast must be bypassed, as these run on just normal line voltage (120v). These burn only 54 watts, yet they put out the light of about 15 100 watt regular light bulbs, or about the equivalent of over 6 4 foot long florescent tubes. For residential use, these are best suited for garages and workshops with ceiling mounted fixtures, as these bulbs are larger than normal residential light bulbs, they need extra space. Remember, these are E39 sockets, an adapter is REQUIRED if these are to be used in residential fixtures. These light up my garage incredibly, and I plan to use these in the garages and workshops at my vacation homes as well. Also great for parking lot HID fixtures at the business, as they burn only a fraction of the power that standard HID bulbs do. Great bulbs, but UNDERSTAND that they are NOT the same sized socket as home light bulbs! The adapters are cheap, readily available from numerous sources online.

The bulbs came quickly and were well packaged so that there was no damage. Perfect for lighting up my workshop. They are large so be sure they will fit in you space. Make sure that you have the e 39 base. Great bulbs! Picture will provide reference for size.
