Don't waste your time replacing the tubes. I've used both LED tubes and strips replacements and neither were as good as replacing the complete fixture with
Raycharm 18.1"X3.9" Rectangular 1440 Lumen Super Bright White Diffused Beam LED Light Fixture, High Light-Output Low Ampere, w/Touch Switch for RV, Trailer & Boat Under-Cabinet/Cabin Lighting from Amazon.
These lights have adjustable brightness and are far superior to LED replacements. The foot print of these fixture are the only replacements that will cover the present OEM fluorescent fixtures.
Any PC owner that has seen my interior says they wish they had these fixtures because of the low profile and 4 choices of brightness adjustments.
