Super easy to re-wire the fixture to bypass the ballast, don’t waste your money on retrofit LED tubes that are supposed to work with existing ballasts but don’t. They are brighter than the fluorescent bulbs they replaced, but the instant brightness is what’s best. Great purchase
No more ballasts to contend with - twice as bright, and never have to change the tube again - all at a tenth of the electricity used.
Good service, good packaging ...Quick to respond to queries ...and they are a Canadian supplier !
