I think you are better off building them yourself to ensure you a regulating the voltage properly, and avoiding burn outs.  You will also save a lot of money.
Plus You won't feel so bad if your home built bulbs fail, not as bad as you would if the $40 ones did.

Alternatively, you can modify those compact floresent bulbs to work on 12 volts as well. You can also buy color corrected ones, the light output is much better than that of the normal florescent color.
Also, buy higher wattage ones for reading under.
I find the lower watt ones- 9-13 watts- very hard to read eith. It seems they kill contrast.

I've done some testing on these high power LEDs, if you do things right you can get 50,000 to 100,000 hours of lifetime, unlike those small 5mm LEDs that just go south from the get go.

Not sure why I bother responding.

Not sure why...

You claim they last over 11 years when the earliest, most primitive versions, only went into production 14 years ago,

You want to long term test 5mm LEDs at DOUBLE their Absolute Maximum Current Rating,
(who long term tests a device at double the absolute maximum ratings for 24 hours, let alone for years?)

Etc, etc, etc...

Whatever.
I lost interest too fast.

Sounds like 110% spam.

Checked your history.  Now it looks like 10,000% spam.
