Will Pure Light LED™ bulbs work on a dimmer switch?

Yes! A lot of our bulb line-up have the option for dimmable and non-dimmable models.

Do Pure Light LED™ bulbs contain Mercury like CFLs?

Pure Light LEDs™ contain zero mercury.  Just as importantly, our bulbs are 90% (or more) reusable and 100% recyclable.

Do Pure Light LED™ bulbs emit UV light?

Pure Light LEDs™ do not emit UV light.  They are perfect for spot lighitng your paintings since they will not fade them.  They are also great for use in jewelry displays.

Where can I use Pure Light LEDs™?

Pure Light LEDs™ can be used in place of virtually any other type of bulb - halogen, incandescent, CFL, florescent:  the list goes on... Simply remove your old money-hungry bulb* and replace it with a Pure Light LED™! (Disconnect power first) View our "Bulb Compatibility" page for additional directions.

*Warning.  CFLs should not be thrown in the trash.  Contact your local waste management company for proper disposal procedures.

What does it mean when you say "warm white" or "cool white"?

This is referring to some of the different white tones available. Warm white is a more yellow color, much more similar to that of a standard halogen bulb; it's the standard warm color we all may be used to. This option is however slighter dimmer than cool white. Cool white is a bluish-white tone. This may be harsh to some people yet pleasing to others. This color is great for outdoor perimeter lighting and generally for areas where you would want a brighter light. This color tends to bring out deeper colors in the illuminated object.

How do I choose the right beam angle?

When selecting a light bulb you'll have two options: 'flood' light or 'spot' light. These are definitions of beam angles. The beam angle is the degree of width that the light is dispursed from a light source. More specifically: the angle between those points on opposite sides of the beam's axis where the intensity drops to 50% of maximum.

The area lit is determined by the distance between the light source and the subject. To light a larger area from a short distance a wider (larger number of degrees) beam angle is used. To light the same area from a longer distance a narrower beam angle would be used.

A narrower beam angle will normally result in a greater brightness or greater number of lumens for the same wattage: the light is concentrated on a smaller area. This is typically done though optics via reflectors or lenses.
