I have upgraded the 48" two-pin bulbs to Costco LED bulbs. That worked fine. I upgraded a circular bulb in a magnifying lamp to a LED bulb I got from Home Depot. That also worked well.
Some of the LED upgrades require you to bypass the ballast and hook the 120V input directly to the bulb. Some don't, so be sure to read the directions.
