Dear all sifus here

I'd love to retrofit t8 led tubes into my existing magnetic ballast housing (with starter).

From my understanding above, if I choose to go with philips ecofit 16w, the only option is method 1 removing the starter. But it has cons such as ballast going failure, ballast consuming more wattage. So if I wanna remove the ballast and rewire I have to get type A LED tubes, right?

I currently use 10 x 18W T8 2ft tubes and 6 x 36W T8 4ft tubes. Would it actually be worthwhile to pay more for the LED tubes?
