There's actually a web page that explains the *multiple* types
of LED tube products, and how to get the best from them.
Type A. Type B. Type C. Type D=A+B ?

With a chart like this, you can see that one product, touts
140 lumens per watt. The industry does not place a premium on
providing efficiency information, so that chart might be all that
you get in the way of hints. What it does mean, is if you
shop around, you might find a good one.

Removing the ballast, and not using Type A, would be a start.

Type A – Easiest Installation

LED Tube with Integrated Driver – Compatible and Operated on Existing LFL Ballast

Type B – Simplest Total System

Ballast Bypass LED Tube – Wired to Mains

Type C – Best Performance

LED Tube with Remote Driver

There's no number for the remote driver case.

The LED tube has a firing angle of 160 degrees and does not rely on
the reflector returning the "back light".

LED versus CFL.
