Can you put a 600 watt bulb in a 400 watt ballast?
You can run a 600w bulb in a 400w ballast and it will fire and put out 400w of light but the spectrum will be compromised.
How long do Gavita ballasts last?
3000-4000 hours (CDM) 2000 – 3000 hours (MH) 30,000 (Gavita LEP)
When should I replace my MH bulb?
MH (Metal Halide) bulbs need to be replaced every 8 months on a 18 hour on 6 hour off cycle.
Do HPS ballasts go bad?
High Pressure Sodium Lamps Normal end-of-life is usually indicated by the lamp cycling on and off. As the lamp accumulated burning hours, its operating voltage increases, eventually becoming higher than the voltage supplied by the ballast. The ballast restrikes the arc.
How do I know if a ballast is bad?
2. Look for warning signs that the ballast is failing.
- Buzzing. If you hear a strange sound coming from your bulbs or light fixture, like a buzzing or humming noise, that’s often a sign your ballast is going.
- Dimming or flickering.
- No lights at all.
- Changing colors.
- Swollen casing.
- Burn marks.
- Water damage.
- Leaking oil.
Why are my new fluorescent bulbs not working?
A dead fluorescent can be caused by lack of electrical power (tripped breaker or blown fuse), a dead or dying ballast, a dead starter or a dead bulb(s). Check for power first… then the starter (if applicable) and then the bulbs. When all else fails, the ballast should be replaced.
How much is it to replace a ballast?
A replacement ballast costs about $10-25 depending on capacity and brand. The bite is that an electrician trip charge (which includes 30 or 60 minutes work) is going to be $75-150 probably – for about 5 minutes work on each light fixture.
How do you test an electronic ballast?
- Turn off the fluorescent fixture’s circuit breaker inside the breaker panel.
- Remove the fluorescent bulbs from the fixture.
- Remove the ballast cover from the fixture, if the ballast is not already exposed.
- Set the multimeter to the ohm setting.
How do electronic ballasts work?
The ballast initially works as a starter for the arc, supplying a high-voltage impulse and, later, it works as a limiter/regulator of the electric flow inside the circuit. Electronic ballasts also run much cooler and are lighter than their magnetic counterparts.
Can a bad ballast cause a breaker to trip?
But in the case of a *malfunctioning* magnetic ballast, that should be removed immediately because it can indeed have consequences. They will trip breakers, melt tar, or even start a fire inside the fixture.
Are electronic ballasts better than magnetic?
In addition to not flickering and being quieter than magnetic ballasts, electronic ballasts are preferred because it has many other advantages. They are smaller in size and weigh less. Also, if you want to replace your magnetic ballast with an electronic ballast, this is cheap and relatively easy to do.
Why does breaker trip when I turn switch on?
Breaker Trips Due to Ground Fault Ground faults occur when an energized wire touches a metal frame or housing unit. This diversion redirects the flow of electricity from its normal path and can overload your circuit, causing it to blow. Ground faults can also cause fires, electrical shock, and insulation damage.
What causes a light fuse to trip?
A fuse switch that keeps tripping is usually caused by a faulty electrical item or an overloaded circuit. Locating the root of the problem is largely a process of elimination and something you can do yourself.
What to do if an appliance keeps tripping?
Unplug all appliances on that problem circuit and switch off any immersion heaters (if you have one). Switch the tripped switch to the ON position and plug in the appliances one by one until the trip goes again. Leave that appliance unplugged, and have it repaired by a qualified electrician.
