Brighter LED replacements.

[rbpru]

Our trailer has the classic 12 volt dual lights and slide switch with incandesce bulbs. I would like to replace them with 12 volt LED lights but I want a brighter bulb with more lumens.

Does anyone know if they make a direct replacement that is brighter?

Likewise my porch lamp seems like an airport approach beacon and I am looking for a dimmer LED version for it.

I got mine from ebay. The key is to get the 5050 panels since they are almost 3x the brightness for the same size panel. I did have to put some hot glue in the connector to get the wires to stay in the right spot.

48 SMD 3528 Pure White 2.8w 190 Lm 60mm x 40mm
48 SMD 5050 Pure White 5.5w 590 Lm 58mm x 43mm

I used both panels and cob style. Where I wanted more diffused lighting I used cobs. My fixture has lenses that diffused the panel light pretty well

I think that 30-5050 LEDs will be quite a bit brighter than the 921 bulb. Also, the 921 is a pretty small bulb. Make sure that the 30-5050 light is not too big physically. Another good reason to buy a couple before buying enough for your rig.

Depends who you ask. I have seen specs that say 200 and others that say 400, and others that are somewhere in between. Personally I don't trust any lumen spec.

How many lumens does a standard 921 bulb put out?

I am using these 921 style http://www.ledtrailerlights.com/rv/RV-T10-48FP.htm in my cargo trailer. They have a lifetime warranty. I've had them 2 years and no failures.

These don't use tape like all the other flat panels I've seen use, so they are easy to change out of you want something different later on.

In areas where I wanted a little less light, I went with the warm white version - http://www.ledtrailerlights.com/rv/RV-T10-15FP.htm

I've switched RVs since doing my first LED upgrade, here's the0 write up from 2009 in my other RV: My EASY LED Upgrade

For brighter lights get lights with more LEDs. I understand there are newer LEDs that are being used in LED lights but I have no experience with them.

I found a big difference between venders on eBay. When you think you have selected the seller and light you like, buy a couple to try before you buy more.

I put my 48 1210 panels in years ago and I find them a good match for the original. We found them overbearing and used 9 LED cobs in the double fixtures on the ceiling.

Were I to do it again I would go with all cobs instead of panels due to ease of install and especially removal. They are so inexpensive that if you change your mind the tape is a pain to remove. Some like what they got and have a hard time getting the tape to stick.

Ease of installation aside, there are other considerations. Type of fixture and lens seem to have a affect on preference. My fixtures have a curved metal reflector and a clear lens. The clear lens has a additional lens that intensifies and projects the light downward. So a cob diffuses sided to side, The reflector makes use of the emitters on the back and the extra lens makes better use of the emitters on the bottom. A nice even light everywhere.

A panel in the same fixture diffuses little and directs most of the light straight down through the extra lens. A very bright spotlight.

I've seen people with the frosted lens prefer panels because the lens diffuses better and the light being directed straight down helps illuminate the area below better.

You would need a Cob style with more emitters since some of them are pointed away from the lens, especially if there is no reflector.

Like tenbear, I replaced my 921's with 36-1210 LED panels from 2011_led on Ebay.
I ordered different warm white and bright white panels before deciding on the ones I have. The 36-5050 bright white panel went into the outside hitch light and the 36-1210 bright white went into the range hood. The lights over the bed are 24-1210 warm white panels, DW thought the 36-1210's were too bright.
If you can find them try a 4000K panel, it looks like more of a pure white color vs the yellowish tint of a warm white or blue tint of a cool white.

You say you want BRIGHTER lights.
I have ordered from ebay and others over the last few years.
Mixed results with most of them about the same yellow lights as the regular incandescent.
If you really want bright this might save you a lot of time.
Here are some comparisons, the brightest being the fixture from Amazon I mentioned earlier in this thread.

STANDARD INCADECENT


STANDARD LED

Go To M4 Products they have 3 different levels of bulbs very good quality no noise on radio or tv replaced all bulbs in side and out ran about $230 could be done cheaper but these work very good. Just got back from 7 days no power just portable 200watt solar set up worked great.

I guess I should have done my homework first. The bulbs I want to replace are 921s, but I also have a fixture with a pair of 1141 bulbs.

Thanks for the web sites and information.

Panels have double sided tape on the back. Cob type plug in like a normal bulb.
