I just use 4 foot fluorescent lights in my shop area. I have 37 of the two bulb 4 foot fixtures in the basement. Once in a great while the fluorescent bulbs die. But its rare. And the bulbs cost $1 each or something like that.

Yep, fluorescent is still a winner on parts/availability/maturity, and was never far
behind LED in power consumption.

I would argue that a 50% reduction in power consumption between fluorescent and
LED does indicate that fluorescent is "far behind LED in power consumption".

Yeah...





I suspect the various (low-voltage DC, high-voltage AC,
dimmable, not dimmable, flickering, flicker-free, etc.) LED options mean that one
can never re-lamp or re-power a fixture, if a lamp or power brick dies, you need... a new
fixture.

You can buy replacement LED tubes for standard fluorescent fixtures, the tubes
run on line voltage, so you simply rewire the fixture to bypass the ballast.

I've converted a dozen F96T12 two-bulb fixtures with LED tubes, which _are_
easily replaceable.

You can also get LED tubes that are drop-in replacement in standard
48" fixtures using the existing ballast.


I discovered the LED florescent replacements a couple of years ago. I
kept having to replace tubes and finally replaced the ballast. AND
STILL had issues.

I went to HD to buy a complete replacement assembly. The sales guy
suggested the LED ballast bypass style. Wow, no more issues.
