What Is The Pentair Globrite?
The Pentair Globrite is an energy efficient LED pool light designed to illuminate residential and commercial pools. These long-lasting, low-voltage lights are easy to install and operate whilst making a very big difference to your pool at large. Even making it entirely possible to take a dip in your swimming pool at night at still being able to see quite clearly.
Pentair Globrite Problems
1. Light Not Turning On
If the Pentair Globrite light in your pool is not turning on then it undermines the basic funtionality of the pool light in a big way. And there may be a problem with;
- Your main circuit breaker
- Burnt out bulb
- Moisture buildup
Troubleshooting The Light Not Turning On Problem
- Check your circuit breaker and GFCI outlets for any tripped switches and reset them.
- Remove the bulb and inspect it for any visible damage or dark areas and then replace the bulb if needed and turn the power back on to test the new bulb.
- Again with the power off you need to remove the bulb and use a hair dryer on a low, cool setting to dry all parts of the light fixture especially any seals or gaskets and let all areas dry completely before reinstalling the bulb and testing the light.
2. Light Stuck On
If your Pentair Globrite light is stuck on and you’re unable to turn it off there are a few possible issues to check and they include;
- A faulty transformer
- A stuck timer
- A bad photocell
- A faulty switch
Troubleshooting The Light Stuck On Problem
- Check that the transformer is plugged in, the circuit breaker has not tripped and the switch controlling the transformer is in the proper “on” position.
- You should try turning the dial on the timer to the “off” position but if that does not work then you may need to disable or replace the timer.
- Be sure to disable the photocell and operate the light manually using a switch because the photocell will need replacement.
- You should flip the switch to the “off” position several times to try and unstick it but if that does not work then the switch should be replaced.
3. Light Flickering Or Dimming
Pentair Globrite lights flickering or dimming over time is a common problem and may be due to factors like;
- The bulb’s lifespan
- A faulty transformer or GFI circuit
- Loose wiring
Troubleshooting The Light Flickering Or Dimming Problem
- If your Pentair Globrite light is flickering or seems to be dimmer then it’s likely time for a new bulb, just be sure to choose a bulb specifically rated for use in swimming pool or spa fixtures to ensure proper brightness and durability.
- The GFI (ground fault circuit interrupter) outlet the light is plugged into may need to be reset by flipping the breaker in the circuit panel. The transformer which converts high-voltage power to low-voltage for the light can also cause flickering or dimming and may need replacement after years of use.
- Also check that all connections behind the light fixture at the GFI outlet, circuit breaker and transformer are tight and secure.
4. Leaking Or Filling With Water
If your Pentair Globrite light is leaking or filling with water then this problem is likely due to;
- A seal or o-ring failure
- A damaged lens
- A misaligned lens
Troubleshooting The Leaking Or Filling With Water Problem
- First you need to turn off the pool pump and filtration system to relieve pressure before disassembling the light fixture.
- Be sure to remove the lens or ring that secures the lens in place and inspect the seal, o-ring and lens gasket for any visible damage, tears or debris and clean or replace any damaged parts.
- Check that the lens and seal are properly aligned and seated because an improperly installed lens or damaged lens track can also allow water to leak in. Also remove and re-seat the lens to ensure it is correctly in place.
5. Transformer Issues
Pentair Globrite transformers are responsible for providing power to your pool lights. If you experience problems with your Pentair Globrite lights not turning on or flickering then it may be due to;
- A faulty transformer
- Low/ inadequate voltage
- Water damage
Troubleshooting The Transformer Issues
- Check that the transformer is securely plugged in, all connections are tight and the circuit breaker has not tripped. If the lights still do not function properly then you likely need to replace the transformer.
- Use a voltage meter to test that the transformer is outputting 12V and replace the transformer if the voltage is not within 10% of the recommended level.
- Check the transformer casing and cables for any signs of rust, corrosion or exposed wires. If water damage is detected then a replacement is required.
How To Avoid Pentair Globrite Problems
- Be sure to gently clean the lens with an abrasive sponge or scrubber and then rinse thoroughly with water.
- Test the light at least once a month by turning it on to ensure it is functioning properly and emitting an even glow.
- Start using a timer or photocell to automatically turn the light on at dusk and off at dawn. This can save energy and also add convenience thus ensuring your pool is well-lit during evening hours.
- At the end of the swimming season turn off the pool light at the breaker and disconnect any timers or photocells to prevent the light from turning on.
How Long Should The Pentair Globrite Last?
The average lifespan of a Pentair Globrite pool light is 10-15 years with normal use and proper maintenance. Certain things like water chemistry, usage frequency and environmental conditions can impact the lifespan of the light.
Why Does My Pentair Globrite Keep Burning Out Bulbs?
There are a few possible reasons why your Pentair Globrite pool light may frequently burn out bulbs like; overvoltage, corrosion, improper sealing, a faulty transformer or the wrong bulb.
Conclusion
As you have seen there are a couple of problems that can arise with Pentair Globrite pool lights, but the good news is there are also solutions for troubleshooting and repairing them. With these troubleshooting tips and the right replacement parts on hand though, many problems with Pentair Globrite lights can be solved DIY-style. Keeping your pool well-lit and the ambiance bright is worth the effort to maintain these illuminators and with regular inspection and care, your Pentair Globrite pool lights should be good to go.
