Most of us are used to using CFLs or incandescent light bulbs which, when in need of replacing, simply stop working.  The filament breaks and the light just doesn’t work.  When the bulb is replaced, the light fixture works again, no problems  This isn’t the case with metal halide lights.

Metal halide light fixtures are built differently and, as a result, need to be replaced prior to burning out.  Otherwise, there could be damage to your ballast.

Not only that, if you’re using your metal halide lights in a grow room or green house, as the bulb dies, it gives your plants less light and a different color spectrum of light as well.  This can cause a variety of different issues and deficiencies in your plants and will at the very least end up lowering their production of fruits and flowers.

So, what are you supposed to do?

Well, with just a bit of regular maintenance your metal halide lights and ballasts as well as your plants will be just fine.

First off, most manufacturers give metal halide lights about 20,000 hrs of bulb life.  This doesn’t mean the light bulb will definitely fail by this time.  This is the point at which the bulb ought to be replaced.  This life span shometal halide ballastuld not be exceeded even if the light is still going.

With this type of a marker, you can easily estimate when you’ll need to replace the bulb.  If you need to, you can even mark the dates on the calendar.  Just consider the date you activated the lamp, then calculate the average amount of time the light is on each day.  This will give you a basic estimate of when you’ll need to replace the lamp.

You can also watch the color of the light change.  Metal halide lights will give off a pinkish color light instead of the traditional bright natural looking light they usually exhibit once they’re close to expiring.  When you see this color change, be sure to change your MH lamp immediately.

In addition to this color change, as the light goes bad, you’ll also notice issues like the ballast making a humming noise, or the light flickering on and off.  Another issue to watch for is the light taking longer to fire up once turned on.  All of these are markers that point to metal halide lights that are about to expire and need to be changed immediately before the ballast is damaged.

As long as you watch for these signs regularly and maintain a basic idea of when each metal halide light bulb needs to be replaced you’ll get years of use from your metal halide light fixtures.  Also, many people who choose metal halide lights keep a few extra bulbs on hand so that they can be changed at a moments notice.  This can help keep ballasts safe and prevent extra maintenance costs down the road.
