LEDs or better fluorescent tubes?

I'm updating an office unit. I want to put daylights (5000k or 6500k) into this unit. Here are pictures of the ballasts and tubes currently installed. I am going to replace all the bulbs in the unit (about 44 tubes). What can I do with the lighting? Are LED tubes an option? Should (or can) I use T8's instead of T12? I'm looking for options.

Those are old ballast (dates back to 1970's).

You'll probably be better served to replace those ballast with new higher efficiency ones that support T8 bulbs. According to Home Depot, they can save up to 40% of your power and then stick with the new T8 tubes.

Going to LED while sounding good really isn't too much of a savings as the old ballast itself consumes a lot of the power and if you factor in the higher cost of LED tubes... Of course, you can remove the tubes altogether and retrofit the fixture with normal LED lights (not the LED tubes).

Which ballasts would I need to get for this? Any links?

EDIT: Would I need to replace the ballasts one-to-one? So each bucket (don't know the name for it) would need 2 ballasts, right?

Yes... but this would be pretty expensive, right? We only plan to stay in this unit for a few years, so I don't think it would be worth the investment.

You have a choice out there... you can either get two replacement two tube ballasts (for four tubes) OR you can get a replacement 4 tube ballast. Most ballast are of a particular physical size but I would take the old one to the store so that you can be sure they can mount in place. There isn't too much of a selection out there for ballast in general I believe the T8/T12 tubes have the same fittings so you should be able to use the existing connectors - but I might be mistaken on that point... but those connectors are cheap anyways.

https://www.homedepot.ca/en/home/p.fluo ... 43259.html <- four tube

Is Home Depot the best place to get this stuff or can I get it cheaper somewhere else?

You can probably get it cheaper at an electrical wholesaler that has counter sales. But they probably won't be able to give you advice or be able to see everything they have in stock...

Does anyone know if the Small Business Lighting Program is still going on and if I can take advantage of it. There's definitely less than $2000 worth of work to do in the unit I'm in.

I quickly spoke to an electrician over the phone and he said that the program is on hold until July but it seemed odd and there's nothing that says that on the link above.

The office unit next to me actually took advantage of this program in 2011 so I know at one point the program was available and offered in the area that my office is in.

I also did a search on the saveONenergy site and Toronto Hydro-Electric (my utility company) shows that it offers this program.

Anyone have more info about this?

The guy in the unit next to mine took advantage of the Small Business Lighting Program back in 2011 and got the same old T12 bulbs and ballasts replaced with a single ballast and T8 bulbs. See the pics here: https://imgur.com/a/XXnnd

Thanks for posting that small business program - crossing fingers we qualify. Sign up on here and wait for email I guess: http://www.torontohydro.com/sites/elect ... hting.aspx

I'm just going to take the the whole fixtures out. I calculated my monthly cost on 6 fixtures (4 bulbs in each) at $34/month. Just on the 4 office lights!!!!!!! Ridiculous.
