Thread about LEDs

GrumpyG · 08-21-2015, 07:56 PM

There was a thread about LEDs, specifically about using the flat "pancake" style LEDs to replace the 921 incandescent bulbs, but I cannot find it right now. I recall in the thread someone who seemed fairly knowledgeable about LEDs was suggesting the type of LEDs in a cylinder shape were better than the flat ones. Also in this thread were sample pictures of the different LEDs, soft light vs cool light.

I've searched for a couple hours, and can't find this thread. If anyone can point me in the right direction, I would be grateful.

I can look in the morning, but I remember the important thing about LED replacements was to get internal regulated lights.

Thanks for your response.

Grumpy,

I cannot find the previous thread either, but based on the thread, I ordered the following pancake lights:
http://www.amazon.com/gp/product/B00..._detailpages00

Note that I installed approximately 16 of the leds this last spring, now only 2 are fully functional and most are now down to only illuminating 3 of the 12 leds per pancake. So I have been moving them around to where I can tolerate less illumination.

I may have received a bad batch, but 35% of the reviewers have rated the bulbs only as a "1" on Amazon.

I am now waiting for another recommendation for warm pancake leds for the 921 sockets that will be more robust.

I bought these lights in May of this year and they have worked fine for me. I remember reading in some thread that it was better to get bulbs that had a voltage range rather than simply 12v... these are 12-24v... supposedly they will fare better with voltage fluctuations. I don't have any of the cylindrical bulbs; I just left the incandescent bulbs in the sconce fixtures. The only problem I had with these bulbs was that they were difficult to insert into the fixtures.

I bought the cheapeast pancake LEDs I could find on eBay,as well as a handful of barrell-style and pinh-head style. We found the reading lamps over our heads (over the Queen bed) were too bright with a pancake, but the single LED pinhead style were just right. At a bout $1/ea, I bought a few extras in case some failed but none have yet. I would try again with a different vendor/product-don't give up on LED!

Thanks for that link. I have been swamped with other work this weekend.

Same blubs I used and they performed well for several trips now. I did also replace the blubs in the sconce fixture and in the pendant lights over the island.. Very happy with them all..

Thanks for the link. I just ordered 20.

If your trailer is using the 921 Incandescent push in light bulbs here is a replacement that I have been running since 3/20/15 or 36 nights camping. These LED run very cool and our converter did not come during any of the trips. With the incandescent lights you could hardly put your hands on the plastic covers on the lamps as they got so hot and the plug in for the base of the light turned brown on many of the light fixtures due to heat. I replaced all 20 inside lights, these bulbs come in packages of 10 each for $20.20, and I purchased two packs and got free shipping. What I ordered was 2 "GRV T10 921 194 24-3528 SMD LED Bulb Lamp Super Bright Warm White CD 12V Pack of 10 from Amazon. Also ran one light all night, still cool. Just added for my 2 cents worth, if it helps anyone.

Thanks here too. I ordered 10 for my 23RB. They arrived today and I installed them. I really like the light they put out. A bit brighter than my original 921s and not quite as soft a light, but I like them. I think they are better than the similar ones that have the warning about fluctuations over 13v. Cost a little bit more, but not that much.

I guess I'll get 10 more and finish the job.
