A 921 bulb is a 921 bulb. There isn't one with more power.

He clearly stated a 921 "look a like". I am assuming he meant if you go with another wedge type lamp in a higher wattage it could cause issues because of the additional heat.

Agreed, however, you can get a look-a-like that would fit the socket. A 904, 912, 916 are all T-5 bulbs and are 16mm diameter as is the 921. I haven't found one that has more candle power than the 921 yet. Not saying for sure there is one, but there is that chance, Im no bulb expert

I've ordered several batches of LED's via ebay and so far I can report complete success.
1st - they're cheap and they have to travel a long way to get to my trailer so I gotta be patient.
2nd - You're buying from China. Yeah, but I'll bet they all (or most of 'em) are made there no matter where they're shipped from.
3rd - You gotta choose carefully. There's 3 things I look for:
1) base, yeah it's gotta fit
2) color (measured in Deg Kelvin or K)
3) brightness (measured in Lumens)

For incandescent bulbs I like to get a color of around 3000K which I think is a "comfortable" color and is described as "warm white". I won't buy an LED replacement that has only the description of color as "warm white" alone.
For just a replacement bulb I try to match the Lumens as close as I can.
A quick Google search yielded this bulb performance table.
Looking at their spec for a 921 bulb I see 105 Lumens which sounds low but the note at the bottom claims that an incandescent bulb output drops by about 60%.
When I bought my first replacements I did the above and only bought one. Installed next to a standard 921 I could tell very little difference, more importantly, the Bride approved. So I ordered enough to replace all the interior bulbs. When we traded for the 5th I bought more of the same to replace my 921's and shopped for replacements for the halogen bulbs the new TT had (2 types). I found what I thought was a good replacement and ordered enough to swap 'em all out and they've proved to be a good match. I also order extras so I'm sure to have matching replacements.
Some folks report the cheap LED's may cause radio or TV interference but I haven't had any problems.

don't believe there is such a bulb...921 is the brightest. that is why it is widely used

REplace TT inside lights with LED

I was at the Nashville RV show yesterday, there was a company there showing LED light replacements which caught my eye. The company was Arconlighting.com In the Jayco 26rks my manual shows that the interior lights are 921 bulbs and the outside patio lights are a 922. Seems simple to me. Arcon offers both a soft LED and a Bright LED replacement bulb. the 921 claim a 105 lumans and the 922 a 60 lumans. Both seem very low in power usage.

We are heading out in a few months to go on a 5 day dry camp in the smokeys so I want to cut back our usage as much as I can. Arcon has a 5 year warranty on their products.

Not cheap but a place to start... I think I need 12 or 13 921's inside and 2 922's out.

I was wondering if any one on here have given them a try... Our local Jayco dealer stocks them (at full price no doubt) ... I"ve searching for alternative sources to buy these... I think that if I change all of our indoor and the two patio lights before we go my chance of a much lower power drain on our battery will pay off. (we are in a Non Generator site).

So, any comments and help would be appreciated.

M4 products are great they have lumen rating wattage consumption and color all listed so you know what your getting.

WEll, I just read alot of the M4 website, pretty good information I"m proably going to order some this week.. I noticed they have some 921's priced about 10.00 ea, they are 921-24-5050-WW Warm White 5050 SMD Light Bulb which are pretty low power.. but then they have some uing a Samsung LEd, for about 12.99 921-17-5630-WW Warm White Elite Series Wedge Base Brightest with Samsung 5630 LEDs the latter claim a much brighter light have any of you compared the two? And Is it worth uping to the higher priced LED's?

Funny, no where on their website do they show the warranty ... anyone know what they are...

The paper work that came with my purchased products didn't have any reference to a warranty, but it did state if there were any questions or troubles to contact them (e-mail) and they would respond within 24 hours (usually much sooner).

Didn't purchase any Samsung LED's, so can't offer any comparison comments.

Intereting, I happen to read about the "Gold Star" LED's from someone on the forum, found them at Amazon 280 Lumens 12 x Gold Stars 92100025-12W Replacement LED Bulb 921 Base Tower 280 Lums 12v or 24v Natural White figured what the heck for about $6.80 ea I'll give them a try...http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

We like a bright environment and sounds like these are just a little brighter than the standard 921 luminescent bulbs

I do like buying from Amazon... any issues and they take it right back, no questions asked!

Very likely it was my thread you read. I took the gamble on the "Gold Star" LED replacement bulbs from Amazon and have been extremely pleased. We have been using them for 9 months now, 25 nights in total. I would absolutely buy them again, they have been great, no "cool blue" color at all.

They offer both a 190 and 280 lumen verion, I bought both but my eye can't tell a noticable differnce.

Also, search around Amazon a bit for the best package/price option. Amazon is the master of dynamic pricing, and these bulbs come blister packed as singles, so if you by 1,2,6,12, etc its all the same just the number of blister packs that come in the box. Thereforeyou might find a quanity less than 12 provides a better "each" price, I know its contrary to they way we think but its all a matter of Amazon's pricing algorithym.

Clubhouse, you are correct, it was your post that directed me to the LED's I did purchase 12 (figured I probably need twice that) but this will allow me to install the lights in enough of the coach that I can get an idea on how they perform. I may buy some of the 4m leds just to compare them ... they will be a little more cost but not a bad idea to check them out. I like the idea of putting them in the outside fixture as well.

My next purchase will be 2 Group 27 deep cell batteries and setup to run them in parallel. We have not done any dry camping and with our tip in May were out for 5 nights with no hookups. Our current set up is one (new in the last 6 months) Group 24 Interstate battery that I will keep charged up and take as a back up for the trip. I"ve seen several posts regarding boondocking ... the test will be for sure with my unit and how it stands up with the LED change out and new set of 2 Group 27 batteries.

Next will be to find a change out of my Jackknife couch that is our Jayco.. it has to be the most uncomfortable couch I have ever sat on....

We upgraded our bulbs to LEDs. They were a bargain at $8 for four bulbs on Amazon. They are a nice bright white light.

We purchased these LEDs for the main cabin area and main light in the bedroom. One set of bright white above the medicine cabinet in the bathroom.

http://www.amazon.com/GRV-24-5050-Su...+led+bulb+5050

We used these in the single lights that we didn't want as bright.

http://www.amazon.com/GRV-24-3528-Su...xgy_263_text_y

We liked the warm white for everything but above the medicine cabinet.
So far very happy with the change.
