# How many LED pot lights per circuit?

How many LED pot lights can I put on a single amp circuit?

Some details:

• 15A circuit is capable of 1800 watts, if I calculate for 80% load that is 1440 watts
• Circuit is dedicated to just the lighting
• Ontario electrical code says max of 12 receptacles or lights on a circuit
• Plan to use ultra thin LED pot lights (not cans)
• For arguments sake, lets say each light consumes 15w (most likely lower)
• Theoretically I can safely power 96 of these lights ( I need a max of 26 )

If I am using the ultra thin LED lights, instead of cans, can I get away with more than 12 of them on a single circuit? My thought process: since they are contained units and not cans, they couldn't be overloaded by user negligence by putting in bulbs that draw more watts, since you can't change the bulbs in these.

• What is the power factor of the pot lights? Commented Jun 28, 2018 at 15:02
• @Harper I am not 100% sure since I can't find that spec. I haven't actually purchases the pot lights yet, but the ones I was leaning to are these (9w each) but unsure of power factor: homedepot.ca/en/home/… Commented Jun 28, 2018 at 15:06
• Those doesn't look like mains lights, so you need a power supply to drive them. I'm not sure about details of Ontario code, but one PSU should count as 1 "receptacle", and how much spots you install on the extra-low voltage side should be outside of code's scope. You need an Ontario electrician to confirm that. Commented Jun 28, 2018 at 16:53
• @Agent_L This is critical to the discussion. I believe that once the PSU is installed, you install to the PSU spec. Commented Jun 28, 2018 at 17:16
• @Agent_L Each of those fixtures comes with a j-box that has it's power supply in it. Sort of like a can light, but with a low voltage connectorized wire to the actual "light".
