In a Nutshell, the T24 Part 6 CEC Residential Lighting regs are as follows:
- High Efficacy/Efficiency Lighting as "Primary" lighting source in Kitchens - controlled via its own switch(es),
- High Efficacy/Efficiency Lighting as "Primary" lighting source in Bathrooms - also controlled via its own switch(es),
- If High Efficacy/Efficiency lighting is used for exterior wall mounted fixtures, then only the Kitchen requires the High Efficency lighting source.
High Efficacy/Efficiency lighting source = Lamps with at least 40 Lumens per Watt output characteristics.
Same lighting fixture may not have a "Universal" Lamp Socket means - like Medium Based Screwshells, they need to be designed for specific Lamps.
Other lighting may be used in conjunction with the +40 Lumens per Watt stuff, but must not be the "Primary" lighting source, and they need to be switched separate from the High Eff. "Primary" lighting source.
