Over head light dim

One of my main over head fluorescent lights is now dim. Both builds light....but very dim. Light is about 18" x 6" and very thin.
Wonder if it's worth trying to repair...or just replace.
Thanks

What is the voltage at that fixture (could be an electrical problem) age of the bulbs?

Probably just need new bulbs - even fluorescents don't last forever. If the bulbs have dark rings at one or both ends, it is definitely time to replace.

Fluorescents aren't very voltage sensitive within their specified operating range - anything above 11 volts ought to be plenty.

Bulbs

Yep....I'm not the quickest. Put one of the bulbs in the other ceiling fixture.
Fixture dimmed...problem seems to be the bulb.
Since all are the same age I might as well replace both bulbs in both fixtures.
Thanks

Consider replacing with leds instead of fluorescent. It's pricey, but you should never have to buy another bulb and the power consumption is about 1/10 (significant if you ever do without shore power). I've replaced all my fluorescents with the Revolution led "tube" from rvledbulbs.com and am very pleased. They pretty much just plug in, with only one wire to snip and spice to bypass the ballast in the fixture.

If you like DIY projects, you might check out this thread for an LED upgrade. I did it to one fixture and now the wife wants me to do another. I rigged mine so it uses a DPDT switch and has a high (5 strips) and a low (2 strips). On high, I use one tenth the power of the fluorescent.

Dim bulbs

Since we never boondock $40 - $50 a bulb seems a little high. Got replacements at Lowes for less than $8. The last bulbs lasted us 5 years
So that's not an issue either. Now...if you boondocks it might beanother story.

I searched Lowes and Home Depot and couldn't find a listing for 12 volt Fluorescent tubes. Maybe that's why there so dim, you're using 120 v tubes in a 12 v system?

It doesn't cost $40 to convert Fluorescent to LED. Here's a roll of LED strip lights that has enough to convert 3 or more lamps. (According to how many strips you put per fixture)

http://www.ebay.com/itm/High-Quality...item3a7924124c

If you don't change out the switch like I did to add a high/low function, the roll of lights is pretty much it.

If you don't like soldering, you can also find connectors that fasten on the end of the LED strip with pigtail wires to hook into the on/off switch.

It doesn't cost
There are no 12 VDC fluorescent tubes. The fixtures in our coaches have a "ballast" that inverts the 12vdc to the voltage the bulb can use.

Dim bulbs

Plus...the bulbs went dim after 4 years. New ones are bright as can be.

Get the scoop on what? 12v fluorescent bulbs? There is no such thing.
