MANY differing grades, K value of LED shop bulbs both in "bypass install" and "ballast compatible" versions.
Looks like $6.99 for a bypass 4000K bulb.
K value refers to the "warmth" of the light. 5000K looks "blue" and industrial to my eye. 3500K is the classic "warm" fluorescent favored by housewives who do laundry and need a good read on "daylight color." 4000K is a kind of "average" and IMHO a better all round bulb.
