    i just bought a E ballast from CTY fish shop in Penang,it is the newly open multilevel LFS that hired LOTS of INEXPERIENCED worker.I wanted to buy an E ballast to build DIY PL light fixture so i ask for E ballast for PL tube,the worker got confused so i show her the tube instead and insist a ballast to run for 24 watt PL tube and ask her it is ok and suitable.The answer from her is yes so i bought it.But when i reach home i found out is a 30 watt E ballast that actually for FL tubes because it had both end that fit to FL light.GOSH.

    so i want to ask anyone can guide me wat to do with it?
    can i use it for my 2X15 FL watt light fixture with this ballast?
    or is there a way 24 watt PL light can suit it?pls help me.

    i believe u can use it,if the connector can slot into the 4 pin PL lights.
    i've tried before,no harm.PL works with slight higher wattage eballast.

    I have a 58W Germans made eballast which state T8 (FL tube) 55W, PL 50W.which means the eballast can be used with 55W T8 FL and 50W PL.

    and another Osram Quiktronic 36W eballast which states to be used with 36W FL and 32W PL.

    so i believe your 24W PL should work with the 30W eballast.
    Don't undersize your eballast,u'll burn it after sometimes.

    The 24W PL should have 4 pins. If we number the pins 1,2,3,4. Then (1,2) will represent a pair and (3,4) the other. These will correspond to the opposite sides of the FL tube as in the eBallast diagram. Just connect accordingly.

    yup! you can use it for 20w fl.
    a ballast can drive a lower rated tube but not a higher rated tube. does not matter if it's pl or fl.
