We got these for an RV that runs mostly on solar power, so the amp draw of incandescent bulbs was a real issue. These are so bright that we only have to turn on 1 bulb where we would normally use 2 or 3, but they do draw a little over 0.4A.

Ya know, these are SO DANG CHEAP I thought they couldn't work.  I put them in my trailer and they work fine.  I do alot of dry camping, and I don't want to worry about draining the battery, so these are great.  Even with them all on, I don't pull as much as one set of the regular lites.  They are not "quite" as bright, but in the area over the bed this is a huge advantage.

I bought these bulbs to swap out the existing ones that came with the MH - they do give off a lot of light but if you're only under the fixture, however; that said, they do save a lot of DC power in the MH and for the price that I paid, it was a bargain vs. buying them from Camping World or other RV stores.  Time will tell how they perform on a longer period.

Got these for our Rv frig . We thought everything would slide towards the front and didn't want to deal with that mess when we stopped. They worked good but we found we didn't really need them as we have heavy duty stabilizer bars on our trailer and that seems to help.

We ordered a dozen to replace a some of the incandescent light bulbs in our RV.  These LED lights are natural white and bright, exactly what we were looking for.  They are noticeably cooler and use less amp according to our meter.  We like them so much that we have ordered additional two dozens to replace all the lights both internal and external.

UPDATE: June, 2017 - these LED bulbs burn out very quickly.  I purchased 24 for our RV and they are almost all gone.  We only use our RV about 2 - 3 months a year.  Don't waste your money and look elsewhere.

I purchased these LEDs to replace my regular T10 bulbs in order to reduce my power consumption in my RV when boondocking.  Regular bulbs pulled 1.2A per bulb.  When replaced with these bulbs I see the current drop to 0.08A per bulb.  88% reduction in power consumption.  My camper has 28 of these bulbs.  The color is pure white instead of a warm yellow but the brightness is on par.  I camp a lot so I am used to LED light so it does not bother me.  You could always mix half and half so that when boondocking you just turn on the LED lights and when on shore power you use the warmer power hogs.  I am definitely happy with these.

Bought 2 of these for our "new to us" motorhome. They work fine, but they won't stop a motorhome that's in gear. DUH! Just remember to remove them BEFORE trying to move the RV  :-o))

Purfect replacement for the plugs on my RV's Onan Emerald 1 GenSet. It wasn't running well at all and replacing the plugs did the trick!

Bought these for my 95 Class A RV's aviation style light fixtures over the couch and chairs.  With the narrow base of the lights they at first did not fit.  the base metal would not allow for the base to be inserted.  FIX I took my small grinder and shaved the flared frame off of the base and they fix and worked perfectly. I have these in my other fixtures without modification.

They work just fine, you might have to rotate the bulb to get it to work but have not found one that won't work, they are great for our RV less power more light

I bought 6 of these https://www.amazon.com/dp/B018HXP7EK/ref=cfb_at_prodpg to use in my sailboat. The boat has a 12 volt DC system and runs on batteries so I thought these would be great, but they all burned out after just a few minutes. Rayhoo contacted me for a review and I replied in email that they had all burned out, so they sent me 6 of these AC/DC versions that look almost the same, BUT they all seem to work! The bulbs put out quite a bit of light for just 2 watts. I don't have much time on them, but compared to the first set they are awesome. Thanks for the customer service.

Purchased for a friend who bought a used RV. Original bulbs were incandescent and generated enough heat to melt lenses of fixtures. These are not only brighter and use less energy but also put out almost no heat compared to the old bulbs. We used them on a trip and they drew very little battery power which came in handy as the site we were at had no hookup. Wouldn't hesitate to purchase these again good quality at excellent price.

These work perfectly in our travel trailer. We like them because they don't get hot like the others.

Lights are bright and now the plastic covers in my rv are cool to touch. The regular bulbs made the covers get so hard.  Only issue I have is I got 3 of them that don't like turning on it seems. They flicker and sometimes will go on and sometimes they won't.
