Led fluo replacements

[minimutly]

bah, bought these led tube things, expecting to rip the guts out of the existing slimline fittings I have, but lo - the 'structions show the "ballast" still needed - but for what?
Can they work without it?

that fills me full of confidence, the last point in section 5 says recommended to work without ballast and section 6 picture shows a ballast being used

They can be used with or without the ballast as long as it's not the electronic type. The starter switch is bypassed effectively linking the two pins one either end together then the live is taken to one end of the fitting and neutral to the other. You can rip the internals out if you are feeling confident and use the existing wires to re-jig the connections. Make doubly sure you follow the instructions to the letter and that live goes to the correct end. Leaving the ballast in is the easier option but they will consume slightly more power due to losses and heat from it being left in and also they say the tube may not work for so long with it still in.
Hope that makes some sense. It is typically badly written!

Thanks for that, it's what I wanted to hear, and really, what I expected - but I was going to have a suck it and see session!

No worries, I have done those exact ones before and had to read the destructions multiple times before it made any sense

easy enough just get rid of the ballast and couple the 2 wires together bypass it

Thanks. On the basis that the ballast is an inductive device, and in series, given the low currents on these I couldn't see what purpose it would serve - none, obviously.

I remember reading there are two types of LED tubes to replace florescent. One is simply a tube swap but actually uses more power as the ballast is still used. The other involved gutting the casing and connecting the LED tube differently.
