Product Information

Full details

The Energizer 7W LED 2D Light Bulb is designed for property managers and homeowners looking to replace inefficient 16W CFL GR8 2-pin bulbs with a modern, energy-saving LED alternative. It provides a bright 750-lumen output in a cool white 4000K color temperature, making it perfect for utility spaces, corridors, and stairwells. While this bulb offers an effortless retrofit installation by working directly with existing magnetic ballasts, it is important to note that it is not compatible with electronic or high-frequency ballasts and is not dimmable.

Extended Product Information

FAQs

Does this bulb work with electronic ballasts?

No, this bulb is strictly for use with magnetic ballasts.

Can I use this with a dimmer switch?

No, this product is not dimmable and using it with a dimmer switch may cause damage or flickering.

What does the 4000K color mean?

4000K represents 'Cool White' light, which appears bright and white, suitable for general task lighting.

How do I know if my ballast is magnetic?

Magnetic ballasts are typically heavier and do not have the 'high-frequency' or 'electronic' label on the casing, which are common in newer, lightweight fixtures.

Is this bulb suitable for outdoor use?

It is intended for interior ambient lighting; it should only be used outdoors if housed within a weatherproof, sealed light fixture.

Troubleshooting

Bulb fails to light up after installation

Ensure the fixture uses a magnetic ballast; if the fixture uses an electronic ballast, this bulb is incompatible.

Bulb flickers continuously

Check that the 2-pin connector is fully seated in the socket and verify that the magnetic ballast is not failing.

Bulb does not dim when wall switch is adjusted

This model is non-dimmable. Ensure you are using a standard on/off switch, not a dimmer switch.

Pros and Cons

Pros

  • Significantly lower power consumption than standard 16W CFLs
  • No rewiring required for magnetic ballast systems
  • Long operational lifespan compared to fluorescent alternatives
  • Provides immediate full-brightness output without warm-up time

Cons

  • Not compatible with electronic or high-frequency ballasts
  • Non-dimmable functionality
  • Requires verification of existing ballast type before purchase

Setup, Compatibility & Care

To install, simply turn off the power at the main breaker, remove the old 16W CFL GR8 bulb, and insert the Energizer LED 2D bulb into the existing 2-pin socket. Before installation, you must confirm your light fixture uses a magnetic ballast. If your fixture uses an electronic high-frequency ballast, this bulb will not function correctly. For cleaning, ensure the power is off and the bulb has cooled, then wipe the casing with a dry, soft cloth to remove dust buildup. Do not use liquid cleaners or sprays directly on the light source.
