I've got a 5 foot T12 fluorescent tube in my utility room that needs
to be replaced. It's a 65W tube (marked F65W / 54-765 / RS) that
gives 4200 lumens when new according to the specification.

I was considering a T8 battern with LED replacement tube, but it seems
these have now been superceeded by integrated LED battern fittings.
Not a problem if the integrated LEDs & driver last for years, but I'm
a bit wary as I've had a few LED candle bulbs fail within a year with
occasional use despite being rated for 20,000 hours.

What's the group's recommended modern option for T12 fluorescent tube
replacement? Any types or brands to look to or to steer clear of?
