Default Garage lighting

I am building a garage. I will be wiring it up and a certified electrician to connect it to the panel.

I live in a northern climate. Which type of lights are better in the cold?
How many lights can be on one circuit?

For a 16x24 garage, what would be a good number of lights that would provide adequate lighting?

Is the garage attached to the main building or free standing?

Is the garage going to be used just as a place to park your car and put the lawn mower or will it be used as a workshop etc. if it is just for the car 2 lights and one outlet is all I would want.

I guess you are in Canada. The electric codes differ a bit from US to Canada so not quite sure what to advise you there. Do you know the CEC and the local codes?

As far as wiring the garage and having a "certified" electrician connect it to the panel. Have you discussed this with an electrician already? Many if not most do not want to take the liability of a home owner running wires etc and then hooking everything up. I know I don't do that. Before you start doing it be sure to discuss this with an electrician who is willing to take this on.

You say you are going to "wire it up". Are you just looking for advice on "lighting" or other advice. As there is much more that needs to be considered when "wiring up" a garage. This is why I say you should plan it out carefully with a licensed electrician. Then if he/she agrees with the plan and agrees to let you do the wiring then proceed; other than that I would not do too much on your own as it could be quire costly for you.

How many access points and will they be illuminated?

Mechanical ballasts in fluorescents, tend to be temperature sensitive, in colder climates.

I'd go LED and more light is generally better than less. LEDs use such a small amount of electricity per lumen given. Are you going to have a panel in your garage? A single circuit for lighting could handle everything you need in lighting. If you plan on using it for a shop one or more 20 amp GFCI protected circuit for outlets. As I recall a 15amp circuit can have up to 10 lights on it based on incandescent bulbs, LEDs draw less 10% of the power of an equivalent incandescent.

In Ontario you are limited to 12 outlets per circuit. An outlet is defined as any point where power is used. The most common outlet examples are lights, receptacles, fans. If the circuit is exclusively lights then you can have more than 12 but the the total watts can not exceed 1440 watts. Use the maximum rated wattage of the fixture for the calculation.
Lighting MUST be on a 15 amp circuit.

Because LED is so much less wattage is there LED only light receptacles? Thus you could put a lot more on one circuit. I would also think insulation requirements around lighting could also change as there is much less heat.

I'm not sure the codes have caught up to the fact that LEDs are becoming standard as incandescents are phased out in the USA (and I assume Canada). If it were a hardwired LED, not a regular fixture with a LED bulb I'd think you should be able to use the wattage of the actual fixture. With a replaceable bulb, you'd have to go with the max wattage for the fixture.

Thatís why LED lamps should have had a different thread maybe and a onetime adapter to fit the old sockets. Then the industry could have sold millions of new fixtures for new construction. Kind of like when they went from 2 wire outlets to 2 with a ground.

My garage which serves as a garage and workshop had 6 two bulb fluorescent fixtures , each bulb gave the equivalent of a 40 watt incandescent bulb. Because of my age iI found it increasingly difficult to replace the florescent bulbs, so I got 6 cheap 2 bulb incandescent fixtures and 60 watt equivalent leds. The fixtures came with opaque light diffuses, which I replaced with clear plastic 8 inch diameter salad bowls that I bought at a dollar store. I just had to drill a hole for the threaded diffuser fitting
Works great with lots of light and I wont have to replace the bulbs in my lifetime. The bulbs were purchased at lowes for a very reasonable price
