Key Points For LED Lights
• Fixtures CSA and UL approved
• Wet locations ,dusty - IP66 or IP65 rated
• Qualified product ENERGY STAR® / DesignLights Consortium
• Color temperature shifting , correct colour? • Power factor requirements
• Check for a strong warranty- warranty period -10-year
Key Points For LED Lights
• Is the lamp dimmable?
– Can’t just use an incandescent wall box dimmer
– low-level dimming ?
• L70 is the point in time when LEDs produce 70% of initial light output
a.k.a. “usable life
• Color tuning strategies
• CONNECTED LIGHTING SYSTEMS – WiFi
