Hi all

Just finished a restaurant. They requested all LED lamps in all the fittings but a day before hand over the designer rocks up with a fluorescent fitting with a Tridonic dimmable ballast.

Never in my 20+ years have I dimmed a fluorescent (except with a DALI system once but that's another story)

Now we wired just a 2 core and earth dimmable supply to the fittings via a Shuttle dimmer and Crabtree bell push.

After Googling a bit I find the only way for that fluorescent ballast to dim is if it has a permanent live, a switched live (bell push) neutral and earth.

At this point the cable is buried under very expensive tiles so no way of installing a 3 core and earth cable.

My only solution is to bypass the tridonic dimmable ballast and install some dimmable LED's

I saw ACDC do 6000K dimmable T8's but designer being designer wants warm white.

Anyone come across any 3000K dimmable T8's.

Just trying to get them out of a fix, they did spec all LED so I'm covered.
