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'...

Here is a link to approx 200 listings on E-Bay Light Panel 48 SMD Led
The 48 SMD panels use the 1206 LED, an older design that is not as bright as the newer SMD LEDs. The 36 LED panels use the 1210 LED while the 24 LED panels use the 5050 LEDs. I think you will find that the 24 5050 SMD LED panels are the brightest, but also the most expensive. I would guess that they are more reliable too.
Some of the ones in the Listing I gave are using the SMD 1210 / SMD 3528
(SMD 1210 (inch): conversion to metric is 3528, means that the length of LED components is 3.5mm, width 2.8mm. So by metric it is called SMD 3528, By inch, it is called SMD 1210.)
Here is the specifications from 1:
Specification:
Voltage: DC 12V
LED quantity: 48 3528SMD LEDs
Color: White
Color temperature : 5000K
Luminous flux: 190LM
Size: approximately 1.57 x 1.97inch(40 x 50mm)
Include 3 adapters: T10 & BA9S & Dome light adapter(suitable for 32-42mm)
I have seen a few 48 LED SMD 5050 but they are in the $ 8.00 range per panel.
Sorry if I misled anyone. I didn't mean to infer that all 48 LED panels, for example, used the 1206 SMD, only that the majority used the 1206. I did see the 48 5050 SMD panel but to me that is overkill. I switched to LEDs to reduce the current drain, not to make it brighter. To me, the 36 1210 SMD LED warm white panels match the old lights and give the best compromise between cost, brightness, color and current drain. Not everyone will agree.
BTW, I don't necessarily believe the luminosity specs given by vendors on eBay. That's why I always advise people to buy one panel/bulb and see if it is what they want, before buying a whole bunch and then being disappointed.
