What's the difference in 12v bulbs? 921 vs 922

[MojaveJoe]

Been replacing my 921 exterior door light bulb about every 40 hours of use. Got some 922s on sale the other day and wondering if I can use them?

They both say 12v but give no wattage ratings.

What would you do?

Thanx,
Joe

I believe the 922 is a higher wattage than the 921; -could melt some plastic... Check at other auto parts stores. I know Sylvania has come out with 921L's (the "L" being for long life, so it must be a recognized problem).

GE921 = 18 watts. GE922 = 12.55 watts.

Check here: Light Bulbs

I normally use a lower wattage bulb over the bed so if I need a light at night it's not so bright. I also put one of the lower wattage bulbs in some dual bulb fixtures in selected places in the RV. Again - it reduces the harsh bright light.

Thanks for all the replies guys.

That link of traveldawg's is a winner.
Search the bulb number and get the voltage and wattage in a few seconds.

Turns out a 922 is 12W while my original 921 bulb is 18W. 922 should make a nice low light nightime bulb for the potty. Now I won't get blinded during someone elses *ahhmmmm* night time trips there *LOL*

Regards to all,

You can also go to Home Depot or Lowes and pick up some of their "low voltage lighting" replacement bulbs.

They are for 12 volts and they go as low as 4 watts on up in various increments (watts).

I think they are a better price than the auto bulbs as well. They come in packs of 4 for the same price as 2 packs at the auto stores.

Good luck, Kevin

We all need to find some kind of LED that works.

Anyone have any ideas?

I'm like MojaveJoe - looking for a dim light in the "water closet" for those late night trips...

I went to the landscape lighting section at the local HD & found all sorts of low wattage 12v bulbs. We've got a 4W blue one in our "throne room". It's not like that tiny closet is made for reading the paper in there or anything like that so the less wattage bulb is sure much easier on the sleepy eyes for those late night trips.
