Rated 4 out of 5 by tedebare had to adjust
I had A row of three grow bulbs, one of which had A regular base, hence the order for conversion of regular to mogul socket. I decided to add another row so purchased three 105 watt bulbs and have two rows of three. In my advanced years I need to relearn to read all the information. 277 volt meant that I needed to run A separate line and timer. It all worked out but learned A lesson READ THE DESCRIPTION.----thanks-----Ted

Bought this bulb to replace a 175 MH bulb. This bulb uses 40% less electricity and provides, at least visually, the same amount of light.
