3. Power Consumption / Dimmability
Dialight
Energy savings
Replace 400W conventional light source with 150W LED High Bay for immediate
energy savings of 60%, even more when you use dimming and proximity sensors.
Dimming
Dimming options for LEDs include STEP dimming for specified light level percentages
or variable dimming for custom light output levels determined by the
installer/customer. A special ballast is required to dim fluorescent lamps.
Bans
“Under the terms of the National Energy Policy Act of 1992 (EPACT) and similar
legislation in Canada many of the full wattage T12 lamps can no longer be
manufactured due to their relative low efficacy and/or poor color characteristics” (The
Lighting Handbook, IES, 10th ed., 7.32).

Colour Rendering Index:
“A measure of the degree of colour shift that a set of test-colour samples undergoes
when illuminated by the light source in question, as compared with those same testcolour samples when illuminated by a reference illuminate of comparable colour
temperature” (The Lighting Handbook, IES, 10th ed., 6.13).

The Resource Conservation and Recovery Act (RCRA) and the Universal Waste Rule
(UWR) regulate the disposal of lamps containing mercury. LEDs themselves contain
no mercury or harmful materials, which require special handling or unique recycling.
