Icanon - you asked about whiter LED. They are measured in "color temperature". Equivalent of old bulb is color temperature 2700K. Sellers call it "warm white" or "soft white" or just "white", don't read too much into this because they may call it anything, ex. "bright white" or even "superbright". They are not very scrupulous, all they want is to sell. Just look into color temps. Temps 3500-4000 will be whiter but they will also be blu-er. Go to Home Depot, they have LED and CFL bulbs of different color temperature shining next to one another for comparison.
Sometimes it may have slight pink shade. There is a filter layer on the LED, and there can be variations in filter color. The seller in my link is where many members have bought from, he seems to have better QC than some other ebay sources. Interesting detail for Canadians - small envelope from Hong Kong arrived with no declared value, so there was no sales tax on mail-order. Usually our govt is charging tax on import over $20.
I'm OK with these LEDs color, changing to different color is not too important but I might try whiter color when will have time. In my shore home all lights are either CFL or long fluorescent tubes, very few regular old bulbs, so I've got used to whiter colors.
Yes, there is some heat but way less than from old bulbs, a good thing in hot summer.

Here is a catch - now I'm spoiled and find that an exact equivalent of an old 18W bulb is dim and yellowish (just like the original 18W was), and want more brightness and white-ness.

We must be willing to get rid of the life we've planned,
so as to have the life that is waiting for us.

One bit of caution. I jumped in there and bought about $150 worth of LED boards etc for the whole trailer only to find out that I was very pleased with how they looked compared to the incandescent automotive bulbs but emitted RF signals that blanked out my HDTV and several of my VHF radio equipment including my ham radio.
This was really a problem when using the OTA HDTV antenna setup.
I finally fell back to just ordering ONE board that did not have any BUCK REGULATOR chips on it to make the LED BOARD operate in a wide range of DC VOLTAGES.
After I found what worked best for me and not blank me out with RFI then I bought more of them.
Just passing on to maybe save you some headaches and maybe some monies...
The $4.99 boards from EBAY/CHINA was what I ended up with.. All still running great since 2009...

Could you link the models you bought? Thanks.
