Winters Coming – Jarvis Corp Tips for Upgrading Before Winter


Jarvis Corp, one of our suppliers, just put up this blog post and we thought it would be useful to share with our customers:

As the day light hours get shorter and the possibility of snowfall increases, it is important to inspect your lighting for any possible problems. It becomes increasingly more difficult to do outdoor electrical work as the temperature drops, so we would like to help you spot the issues before any polar vortex returns. 
  • Look for a cycling fixture – A telltale sign a metal halide fixture is about to need some work, is when the fixture cycles. This is when a fixture turns on and burns for some length of time, this can be as little as 15 minutes or as long as 3 hours, then turns off. As the fixture cools down, it is then able to restart. However, once a fixture begins to cycle, it will not stop and only get worse as it is left on.
  • Dimming – Another sign an old fixture is reaching the end of its life is if the fixture is noticeably dimmer. As the fixture ages it will lose some of its capacity, but if you notice it is substantially dimmer than those around it, it needs to be replaced.
  • Slow Starting – If a fixture takes a long time to start, it will need to be replaced soon. It means that the reaction in the fixture is not happening at the optimal rate, and like when a fixture starts to cycle, will only get worse.
  • Flickering – Flickering is not necessarily a sign that your fixture needs to be replaced, but that something is wrong. The bulb or ballast could be failing, there could be faulty wire connections or issues with your power.
An important thing to note is that even if a fixture no longer works, it still is consuming energy. As long as the ballast is connected to live power, it will drain power.

If you have any questions concerning these issues or if you have any other questions please give us a call or shoot us an e-mail.
