LED SMD 5050 Bulbs

I really do think before I post this stuff :)

I assume you might live in place with no electricity, so stretching battery life on everyday use is important.
In my RVing I drive at least every 3 days, so get full batteries recharge from the engine.
My coffee maker via inverter takes about 150 amp from my batteries, so even full 1 amp more for lights is not going to worry me.
Manu fact, I did not convert few fluorescent lights in my camper.
That is simply not cost-efficient at this time.

I did what Roy did for some fixtures, but bought direct replacement LED bulbs for the fixture he is showing.
I learn that you buy the biggest number of LED you can find for that application and I remember my boards have 48 pcs.
When the boards have to be used in some fixtures due to wedge, or tube sockets, I like rounded LED bulbs for overhead lights as they spread the light more evenly.
New technology Mexico is mentioning might sound interesting, but do I really care if my lights use 1 amp , or 0.98 amp?
I think the biggest advantage is LED panel in refrigerator. Not only much more light, but the old tube bulb at 10W did produce noticeable heat.
With those self-stick boards I am thinking about adding 2 more for the fridge and if I figure out a switch, one for freezer as well.

I see the COB panels taking off- I got a flashlight using that technology, and man is it ultra bright. The COB tech puts the LED directly on the circuit board for better heat dissipation, plus fits a lot more in a given space.
COB panels look like this:

Just got notice from a Chinese LED manufacturer that new generation 195 lumens per watt SMD chips are arriving on the marketplace. These are ISO 9001 grade so it isn't hyperbole. The efficiency means less heat generated. Something tells me these chips aren't going to be cheap - at least not at first. 1950 lumens per 10 watts is nothing to sneeze at.

5050 SMDs are so 2012 maaaaaannnnnn,

Get with the times you dinosaur!!!

How bright any LED chipset is depends on how hard it is driven.

I went through a bunch of LEDs seeking more brightness, and most of those were the 5050s and man did they vary in brightness, independent of the actual number of 5050s they smushed together.

I have been more impressed with more recent offerings of 5730 chipsets.

But honestly, its been a while since I dabbled with new offerings.

And I certainly do not believe lumen or wattage claims.

I'm sure glad that back in my early days of researching for LED REPLACEMENT lights I only had a couple of sources...

They were only available from EBAY CHINA in leds placed on board panels with adapter cords for the various automotive type DC bulbs sockets...

I ended up with this 36-1210 SMD LED Light board, Warm White DC12V which cost $4.99 or ten each for $45 from ebay china...





The WARM WHITE was the best for me to use in the ceiling lamp fixtures... Some folks would add special lens to spread out the light better... Also the boards without the built-in REGULATOR CHIPS on the boards were best to purchase so that the generator RFI signals would not interfere with your HDTV TV signals and other radio electronics like the WX Radios, Ham Radios, etc...

COOL WHITE LEDs are probably best to use for reading.

Perhaps you can get some demos at places like OFFICE DEPOT before buying a bunch of your new LED units...

Sometimes buying just ONE saves in the end...
