All ballast manufacturers recommend replacing ballast every 2 years.
It may sound like they just want to sell more ballasts but the truth
is, as the ballast reaches the end of its life, it cycles and
constantly is trying to re-fire the light bulb. This causes premature
bulb burnout, additional energy usage, and a diminishing of the
quality of light. It doesn't pay to be penny-wise and pound foolish
when it comes to your ballast. You can buy singly or by the box.
New fixtures are no longer manufactured with magnetic ballast
and after 2010 magnetic replacement ballast will no longer be available.
Can be purchased in singles or by the box.
Orders over $200 receive a 10% discount.
