All 10 installed, all worked great. Before that I bought a ballast from Phillips and I don't like it. Just because the Phillips ballast turns on with a delay. Robertson ballasts turn on instantly. I've also found that bulbs that don't work on old magnetic ballasts often work on these electronic ballasts. I put them in Loa lights, cheap Walmart lights.
