Q: What do you mean by Watts, lumens and lamp efficiency?

A. Watts measure how much power a lamp uses, while light output is measured in lumens. Efficiency can thus be calculated in terms of lumens per Watt. Light sources differ in their efficiency ratings, meaning that the amount of power used does not necessarily reflect the amount of light emitted. Even LED products can vary in their efficiency, and are becoming increasingly efficient as technology develops. Traditional light sources such as halogen and incandescent lamps produce light through heating a filament, so most of the energy used in these lamps is wasted as heat. LEDs product light in a different way and do not produce as much heat, making them much more energy efficient.

Q: What is color temperature?

A. V-TAC offer lamps in warm, cool and natural white with color temperatures measured in Kelvin (K). The lower the color temperature is, the warmer the light given by the LED: Warm white = 2800-3500K Natural white = 4000K Cool white = 5000K+ Warm white creates a lighting scheme that more closely matches the light given by traditional halogen or incandescent lamps, while cool white creates a lighting effect which appears closer to daylight, with natural white light creating an effect that lies somewhere in between these.

Q: You said that the lights are dimmable. Can I use my existing dimmer switch?

A. Fixtures that are dimmable use 0-10v dimmable switches.

Q: What is your warranty policy?

A. All Fixtures come with a 5 year warranty.

Q: How long will it take to get my order?

A. When product are in inventory we work on getting products on within 24 hours and no later than 72 hours.
