What is lumen depreciation in HID lights?
HID bulbs lose brightness over time, often dropping to 60–70% output halfway through their lifespan.
How do HID ballasts work?
Ballasts regulate current flow to HID lamps, ensuring stable operation and preventing flicker or premature failure.
Are HID systems suitable for cold climates like Alberta?
HID lights can struggle in very low temperatures; LEDs perform better in cold weather applications.
What are the main types of HID lamps?
Common types include metal halide, high-pressure sodium, and mercury vapor, each with distinct brightness and color profiles.
Can HID systems contribute to high energy bills?
Yes, HID lights consume large amounts of power and often operate inefficiently if not regularly maintained.
How can businesses transition from HID to LED smoothly?
A lighting audit determines compatibility and provides a retrofit plan that minimizes downtime during installation.
Are HID systems recyclable?
Certain components like metal and glass can be recycled, but mercury-containing lamps must be disposed of through approved facilities.
Why do many companies replace HID with LED lighting?
LEDs outperform HID in efficiency, brightness, and lifespan, offering long-term savings and reduced maintenance.
How long do HID lamps typically last?
Metal halide lamps last around 10,000–20,000 hours, while high-pressure sodium types can last up to 24,000 hours.
Why do HID lights take time to reach full brightness?
HID bulbs require time to heat gas inside the lamp to produce light, typically taking 2–5 minutes to reach full intensity.
