5) Reduced maintenance – need to be replaced less often.
6) No infrared (heat) or ultraviolet radiation – will not destory artworks and artefacts.
7) Durable – much more resistant to shock and vibration.
8) Instant on – need no time to 'warm up', unlike fluorescent tube lights
9) Flicker free – unlike fluorescent tubelights,LED lights do not flicker.
10) Dimmable - Some LED lights are designed to dim with existing dimmers without flicker.
How efficient are the LED lights?
Compared with incandescent bulbs,LED lights are generally between 60% and 90% more efficient than equivalent incandescent lights, emit less heat, and last many times longer – up to 50,000 hours compared with 1,000 to 3,000 hours for incandescent lights.
Compaired with fluorescent lights,LED lights are generally between 20% and 40% more efficient than equivalent fluorescent lights,fluorescent lights, and last many times longer – up to 50,000 hours compared with 9,000 to 10,000 hours for fluorescent lights.
Why expensive compared with tradititonal lighting?
LED lights generally cost more upfront than traditional lighting but are much cheaper in the long run due to lower operating and maintenance costs. The solid-state technology in LED lights is more energy-efficient than traditional lighting but costs more to manufacture, hence the price difference.
