This may be a dumb question...but....I have a lot of interior bulbs burnt out that I need to replace. I was looking around on Amazon and they have some good deals on LED bulbs. Can I use LED bulbs to replace the regular bulbs without making any modifications to the lights?
 
I've replaced ALL my interior bulbs with LED's. Just make sure that you get the right base. ..Willy.
 
Another thing to be aware of is that many of the cheapest LED replacements are old stock, old technology LEDs that are too blue, too dim and not as efficient as newer ones.


LEDs can work poorly in some fixtures that were designed around a filament light source.  I have some interior fixtures that project light good with an incandescent, and very poorly with a radially and forward firing LED.

When I use a LED bulb with a single element which fires only forward in these lights, and does not attempt to use the reflector, the light output is quite good.

If you can post a picture of the lights into which you intend to install LED bulbs,, and the failed bulb bases, we can recommend which style will work best.

Newest LED bulbs use 5730 chips which are larger and brighter than 5050, but the offerings at this point, are fewer. 
 
I looked up the 5730 LEDs on ebay. In a warm white T10 base there was only one page. I'm use to searching many pages with a LED search. What is surprising is for being the newer tech, the prices are not any higher. If anything they are cheaper. I could replace the LEDs in the trailer for a quarter of what I spent 3 years ago.

I find that people with frosted domes like panels because the dome diffuses the light so well that they need the one direction of the panel to get the light to extend down. I have clear domes with a intensifying lens in the middle and a reflector on top. A panel in these acts like a spot light with little diffusing. A cob style will use the reflector to give good over all light while the extra lens intensifies the downward light some. I use the cob style in the overhead lights to light up the trailer while the panels are in task areas above the sink, stove, dinette and bathroom. The cobs are actually much dimmer than the panels on purpose, 8 of them light the trailer comfortable and we turn on the panels as needed.

One thing to know is some LEDs are regulated and usually more expensive. The purpose is that when you are charging your battery with higher voltages, the LED will stay at a lower voltage and not heat up as much. That sounds good until you turn on your TV or radio and get RFI. It's never been a issue for me since we charge with solar in the daytime.
 
COB does not refer to the shape of the LED, like a corn cob, though I thought so once.

It stands for Chip on Board.
