Frequently Asked Questions

1) Do these bulbs have a warranty?  Yes, we warranty these bulbs for one full year.  In the event of warranty claims, we pay for all return shipping.

2)  Where can I use these bulbs?  These bulbs are not made to just screw in to any old table lamp in your house.  These are normally used in commercial and industrial type fixtures that have a ballast to ignite the bulb.  Please call if you have any questions about the bulb type you need.

3)  What is a medium base metal halide?  A medium base bulb is a standard size, such as that in a regular household socket.  If you have a bulb with a larger base, this is called a mogul base.  Check out our Ebay store for other listings with the mogul base.

4)  What color of light does high pressure sodium put off?  A yellowish colored light.  If your fixture emits a white color, it sounds like you probably need a metal halide bulb (which can be found in our Ebay store).  Call with any questions.

5)  Why should I buy from Cors Lighting?  We have been selling on Ebay since 1998 and offer quality products at low prices.  Based in Jacksonville, IL we are strategically located to where we can ship to the East, West, North and South and normally have the bulbs in your hands in just a few days.  We normally ship within 1 business day, meaning you can expect to receive tracking information rather quickly.
