Trying to find light bulbs for the garage!

[Ole_Red]

Just as the title says, I'm trying to locate the bulbs pictured below. There are 4 of these fixtures in our garage and they are all burnt out or missing the bulbs. As far as I can tell, they are older industrial fixtures. I would like to get energy efficient bulbs to replace these 300w'ers. They are about 8-10" in length. I can get more accurate measurements tonight if it will help.

What about some of those large CFLs to replace it?

The base is a big part of the problem with these bulbs. The long neck is necessary for the fixtures that they go in. Maybe this is a good time to alter the fixtures or replace in favor of something that is more efficient.

Do you happen to have a pic of the whole fixture to help with ideas?

I would consider going to t-8 florescent fixtures. Much better light and much higher efficiency. Mike

You can buy extensions that screw in that should solve your depth issue pretty easily.

those are mogul base 300w bulbs. I think the silver is so that the light isn't direct but goes upward to where there presumably is a reflector giving light that isn't blinding to look at.

Those bulbs are difficult to find though HD has them without reflector in a 3-way bulb (not what you're looking for). Go to a lighting shop, electrical supply, or look online and if you keep those fixtures, order a case or so of the bulbs. Once you see the price, you may choose what you were suggesting as plan B -- T8's.

 

[Oldbear]

An industrial supplier around us (Gregg's) has the mogul base bulbs, but not with the silver reflector. Check your local industrial suppliers.

Or take the oppurtunity to change over to CFL or LEDs. We're test-driving a new LED fixture at my work - to replace the big mercury lights. No idea on price yet - as it is a testdrive...

Let us know what you do

Yup, mogul base 300w bulbs. Not many around anymore, and I've never seen the reflector coating on such a large bulb, only on 60 or 100W bulbs used in store displays, etc.

300 watt medium screw base bulbs are much more readily available. You can buy a mogul to medium screw base adapter at Home Depot.

 

[Ole_Red]

I'll get a picture of both style of fixtures tonight. I might look at getting the adapter and keeping the fixtures for the time being, especially if they help extend the fixture to allow a broader range of bulbs. Are there medium screw base bulbs that are more efficient than the 300w125v?

A regular incandescent bulb gives out more lumens/watt the higher the wattage of the bulb. So one 300 watt bulb will give more light than two 150 watt bulbs, etc. So theoretically if you put 500 watt bulbs up there you could get away with less bulbs.

Long life incandescents produce LESS lumens/watt than regular life bulbs. A bulb rated for 130V run at 120V will produce 25% less light, use 10% less electricity, but last twice as long as the same bulb rated at 120V.

Halogen bulbs (which a version of incandescent) are more efficient that regular incandescents.

For real cost saving you need to switch to CFL or LED bulbs if you want to keep using the same fixtures. But the price can be prohibitive. What's the point of saving electricity if you barely save money when you factor in the cost of the bulb?

Let's blow your mind with these two opposing options:

The reflective material is to stop glare so don't worry about that. It also reduced light. What you don't say is your voltage? Makes sure your mew lamps are the correct voltage. Yours could be 120v, 240v or even 277v. To deal with the length of the neck you can use mogul to mogul socket extenders or mogul to medium base socket extenders if your new lamps have a medium base. For wattage, you would need a 75 watt CFL to put out the same light. It would probably even put out more light as you have silvering on your current lamps. Look at the following link for technical data. The 80 watt version should work fine for you. http://www.maxlite.com/product-documents/SKQ/DataSheet_SKQ80EAWW.PDF

Search Par 20 triple LED.

What about these? 400 watt equivalent output with 100 watt usage. I am using these in my garage, so far I have 2 hooked up in a 24X36 ft. garage with 14 ft. ceiling in the center. The light is actually good enough to work in there, better than I thought it would be.

Check out this thread by VENO, they sure are cheaper than buying new fluorescent fixtures and bulbs.

Thanks for the link. I will have to check it out when works slows down.

The price difference is astonishing. I may end up going with those $6 bulbs, especially for the price and how often they are turned on.

Jim, what is the base size on these?


I completely forgot to take pictures of the fixtures last night and this morning. Will have to do that tonight when I go out to work on the 65 Stude.

Red,
these are the normal household bulb base, you would have to change the mount, or get an adapter.
