Thread: Shed lights - LED tubes

I don't think any LED tubes will work with the electronic ballasts.
LED tubes don't actually need a ballast to operate but for maximum efficiency, longevity and safety, there are special LED ballasts that they can be used with.
Most LED tube replacements have ballast (for LEDs its just a resistor) built into the drivers as do most LED drivers.
You will see these advertised as "bypass ballast" LED tubes.
eg 4FT T8 LED Light Tube Single-Ended Power Bypass Ballast Milky Lens 4500K AU RO | eBay
No idea of the quality of these but for $6 a tube there's not much to lose. No warranty period stated.

If you decide to install separate LED ballasts make sure you are sitting down when you price them
see The Complete Guide To Lighting Ballasts | RS Australia

FWIW I had corroding disintegrating magnetic ballasts in my 40 year old twin fluoro fittings but the ballasts were chewing 3x the power of the tubes so I removed the starters and ballasts and they have worked fine for many years.
These are the ones I used 10X 25X GermanAEG LED T8 glass tube fluorescent Light 9W 18W 60 120cm COOL FROST | eBay
These come with a 3yr warranty. I installed around 20 of these I'm my shed about 5 years ago and I just recently had to replace one tube.
However, please be aware of what I said above.
Please be careful about fiddling with these and check with your sparky before trying this on your fittings.

By the time you replace the ballast and the tube on an old fluoro light fitting to convert to it may be safer and cheaper to buy completely new LED lights. Then you'll know it should be a safe, efficient light.

It appears from a Youtube vid I watched last night, that I can just bypass the ballasts and wire straight to the LED tubes.

I will look into this more before doing it though.

My experience working with an electrician - you can replace your standard fluro tubes with LED tubes BUT the regular starter is replaced with a special LED type starter fuse and it can have an iron core ballast (or no ballast) but not an electronic ballast. They will not work in a situation where two tubes work off one ballast.

There are a variety of LED tubes available and they must match the fitting.
If in doubt seek qualified assistance.

Down to the local Green Shed and I bought these:
Osram 16W 230V 4000K LED Tube Light - 2 Pack | Bunnings Warehouse

1800 lumens is not very bright -- even if it's an "upgrade"

I'm currently using LEDs that deliver 4000 lumens at 4000K.

Perhaps swap the Osram LEDs for something like this Deta 36W Twin Fluorescent Bare Batten Light With Cord And Plug Light output is 6700 lumens

Ignoring cost, is there a technical difficulty in replacing a neon tube light fitting with the newer LED tube fitting?
One would think that the respective "footprints" would be identical and it would only be a matter of wiring up the new fitting?

As I said above, for standard fluoro LED conversion the starters must be removed.
If the old fluoro fitting contains a magnetic ballast these can be left as is and LED tubes installed and they should work.
However the mag ballasts will chew power, usually more than the LED tube.
Electronic ballasts cannot be used and need to be removed and then the tube fitting needs internal rewiring.
Apart from removing the starter these mods can be fraught with danger and are not recommended for DIY unless you know what you are doing.
For most DIY folk it’s safer to buy completely new fittings.

I'm starting to think this is more a job for my electrician, than an upgrade for me to do, which is a bit of a shame.

Wongdai have you seen this thread - LED Lighting Panels - where to buy? - and specifically the link in post #5 - Philips SmartBright LED Batten 11W (600mm) or 21W (1200mm). Could be a good way to go.

Go to Alltools in Collier road they have LED tubes that only require the starter to be removed and they work a treat. I replaced the twelve fluoro's in my shed with them along with replacing the dozens of em where I work when the existing fluoro's blow.

Hi Rod, are you able to confirm that they work with electronic ballasts?

As I said all that needs to be removed is the starter. Go and get one and ask if it doesn't work will they take it back.... simples

When I bought mine they were supplied with replacement LED starters (which may have been to ensure that I removed the flouro ones).

Maybe a call would be better as he’s already done this once and probably doesn’t want to keep doing this. However, given the poor state of staff knowledge in stores these days maybe that would be just as much a waste of time. I don’t understand why the manufacturer can’t specify this as I’m sure it would save folks a few headaches.
