What light color should I choose?
Warm White is equivalent to a standard incandescent light color and is most popular for residential applications. It has a slight warm yellow glow to it that many people find comfortable and we are all used to seeing in our homes. It is a 2700-3000K on the Kelvin Light Color Scale.

Cool White is equivalent to a standard CFL or Fluorescent light color and is most popular for commercial applications, although it is also used fairly often in residential. It puts out a pure white without any yellow undertone. It is a 4000-4500K on the Kelvin Light Color Scale.

Neutral White is a very pure white, most popular for commercial applications, although it is also used fairly often in residential. It puts out a pure white without without any blue undertone. It is a 5000-5500K on the Kelvin Light Color Scale.

DayWhite™ most closely replicates natural daylight and does have a slight blue hue to the light output. This is rarely seen in residential applications as the light output can seem a bit harsh and bright, and is most commonly seen in exterior or commercial applications. This is the brightest of the White light color options. It is a 6000-6500K on the Kelvin Light Color Scale.
How do I know what power supply to purchase?
The method to calculate your required power source for a low voltage light installation would be to take the watts per light (in the specs section of the product you are interested in), multiply by the number of fixtures you plan to install, and then add 20% to that total. The resulting number is the minimum number of watts your power supply needs to be, so round up to the next available size power supply.It never hurts to go with a larger power supply. Your lights will only consume the number of watts actually being used when they are on.
Is this fixture UL listed?
Many of our products are UL listed. To confirm, please review the Certifications listed under the product specifications section of the product you are interested in.
