I know the draw, it's nearly 200W. That bulb is likey a 175W bulb, as most MV bulbs are, but there are some around 200W.check the power draw on that mercury vapor light !
They do make cfl flood light bulbs (standard screw in base). They put out a lot less light, but you could probably install 10 of them and draw less power than one mercury vapor.
The age of the fixture makes me believe it's a ballasted fixture, but I want to make sure it was never switched to "unballasted". -- I have a mongul bulb base.
I knew before I bought the house I would make the change, this light is around $8-$9/mo during this time of year.

Thanks, & Good Luck, bacpacker!excellent project luvit. I will be beginning something similar at my place by march. ..But summer time the ac runs a lot. Still looking at ways to reduce that.

Awe no, it's a combination of many things.what have you identified as the largest power hog in this home right now? I ask because this number still seems rather high for a daily usage??
is this really just the electric heat & lights??
Hoggishness, in respectful order.
- 3 women in the house who don't care.
- Poor Home insulation and efficiency
- Electric Clothes Dryer
- Electric Range & Oven
- Electric pumps (2) for the boiler run 24/7
- Electric forced air fan
- Outdoor Mercury Vapor bulb >12hrs /day.
- TV, etc.
- Recessed lighting (groups of 6 bulbs per switch @ 60W each bulb).. albeit, not used often.
- All sorts of vampire draws.
- 3 women in the house who don't care.
Thanks to the whole house meter, I'm well educated of the poor insulation and efficiency of the windows.. check-out the chart. -- the forced air fan runs for 4-6 minutes and turns off for 4-5minutes.. This house just isn't holding the heat.
It feels warm and consistent, but it's losing the heat almost as fast as it generates it.
Also, my low point is nearly 400W (sometimes 300W), due to the boiler pumps, MV Bulb, vampire draws, and sometimes, a teen daughter may leave something on when they leave the room/overnight.

I own one and used it to track my pool pump usage for a few seasons....local libraries in my area have the kill-a-watt meter available for 'check out'. You might want to look into that.
I certainly have vampire draws, but I'm spending time on picking the easy cherries, but planning to tackle the real problem.. home insulation and windows.
See the chart, above, it shows my low point is nearly 400W (sometimes 300W), due to the boiler pumps, MV Bulb, vampire draws, and sometimes, a teen daughter may leave something on when they leave the room/overnight.. but the chart shows the forced air fan kicking on often due to heat loss in my home.

I pick my battles, as long as I see my daughters showing effort towards improvement, I don't pester them.
