    I want to replace some fluorescent D shaped tubes with LED.
    They are in the entrance foyer and the toilets of a church. I've fitted PIR sensors as people kept leaving the lights on. I'd like LEDs as they use less electricity and start virtually instantly. I know that I'd need to change the starter.
    Does anyone know where I can get replacement tubes that are LEDs?
    I don't want to change the whole fitting as that would be expensive. I'd rather replace tubes as the existing ones fail.

    First question - do you know if these fittings have an electronic or a wire wound ballast? do they all have a replaceable switch starter? Also are any of these fittings combined emergency lights?

    Thanks RF for replying.
    I know none of them are emergency lights.
    They have starters that look like the starters in a "normal" fluorescent batten fitting.
    They are roughly 20 years old if that gives any idea of what they will be.

    I forgot to ask - are your existing lamps 16W, 28W or 38W?

    Thanks.
    How did I miss that? I use CEF so should have looked at them.
    The advantage of changing the "tubes" is that if I do a few at a time they will still look the same. If I change the whole fitting I'd need to do them all to keep them looking reasonably uniform. possibly a better option (I'll ask the treasurer)
