How to convert to LED lighting
Hi, I think some of you will be interested in how I converted my RV lights to LED. I initially tried 12 volt LED bulbs about 5 years go, and they were not satisfactory: they were expensive, didn'...

My Open Range has some kind of off brand Chinese fixture (Pai Ying)with two 921 lamps but they face each other toward the center with a mirror reflector above the center. The spacing between sockets is only 2 3/4". It looks like fixture modification or replacement will be necessary in order to use the panel type LED's. Even the paddle type looks too large. I hate to make permanent modifications to all the fixtures but I can't see any options.
I found the rating for the 921 lamp to be 264 lumen. The 5050 LED is rated 15 lumen each (5 lumen per imbedded LED) and the 3528 is rated 5 lumen each. Reducing the light output is not an acceptable option for me. Maybe a single 48 LED 5050 would work.
I have not seen a reasonably priced 48 LED panel with 5050 LED's. Yet what I did was put two of the low cost 24 LED panels into each of my bathroom fixtures, and 4 into the porch light.
24 X 15 = 360 lumens. 720 for 2 and 1440 for 4? I don't think they are that bright though. That might be a bit optimistic.
If it is 90 lumes per watt, and 4 of the 24 LED panels are a total of 6 watts (according to my e-meter) then that would be about 560 Lumens.
I recall a 75 watt light bulb being something like 600 lumens, and I don't think the 4 panels in my porch light are nearly as bright as a older 75 watt bulb. Yet it might be within 50% to 75% as bright.

I found a few listings for 48 LED 5050 panel for as low as $4.16 with free shipping on ebay.
The question I have is the 48 led 5050 3 x as bright as my 48 led SMD panel as the 5050 has 3 times the emitter?
