Product Information
Full details
This Kosnic LED 2D Light Bulb is designed for those needing a reliable, energy-efficient replacement for 28W CFL GR10Q 4-pin bulbs in ambient lighting applications like corridors and stairwells. Its key benefit is a significant reduction in energy consumption and maintenance due to its long lifespan. A key consideration is that it requires ballast removal for installation. This bulb offers switchable CCT (Color Correlated Temperature) between warm white, cool white, and daylight, providing flexible lighting options.

FAQs
What is the main advantage of this LED 2D bulb over a traditional CFL 2D?
The main advantages are significant energy savings (12W vs 28W), a much longer lifespan (30,000 hours vs typically 8,000-10,000 hours), and instant, flicker-free illumination.
Do I need to replace my entire light fixture?
No, this is designed as a replacement bulb. However, you must remove the existing ballast from your fixture before installing the LED bulb.
How do I change the color temperature (CCT)?
The CCT is switchable directly on the bulb. Typically, there is a small switch that allows you to select between 2700K (Warm White), 4000K (Cool White), or 6500K (Daylight White).
Can this bulb be used with a dimmer switch?
No, this Kosnic LED 2D light bulb is not dimmable.
What does 'Plug & Play Emergency Module Ready' mean?
It means the bulb's circuitry is designed to work seamlessly with a compatible emergency module, allowing the light to function during a power outage without needing a separate, complex setup.
What are the physical dimensions of the bulb?
The approximate dimensions are 192mm in length, 192mm in width, and 31mm in depth.
Is it safe to remove the ballast myself?
While possible, it involves working with mains electricity. For safety, it is highly recommended to have a qualified electrician perform the ballast removal and wiring modifications.
Troubleshooting
Light does not turn on
Ensure the power is switched on at the mains. Verify that the ballast has been correctly removed and the wiring is secure. Double-check that the bulb is properly seated in the socket.
Flickering light
Check all electrical connections for security. Ensure there are no incompatible components in the circuit. If flickering persists, the bulb may be faulty; contact the supplier.
Light color is incorrect
The CCT is switchable. If the color is not as desired, carefully check the switch mechanism on the bulb itself to select the preferred setting (2700K, 4000K, or 6500K).
Bulb appears loose
Ensure the bulb is fully inserted and the twist-and-lock mechanism (if applicable) is engaged. Do not force the bulb; if it feels loose, check the socket for damage.
Pros and Cons
Pros
- Substantial energy savings compared to older CFL bulbs.
- Flexible lighting options with three CCT settings.
- Reduced maintenance costs due to an exceptionally long lifespan.
- Instant on and stable light output without flickering.
- Modern, efficient LED technology.
Cons
- Requires ballast removal for installation, necessitating professional electrical work.
- Not dimmable, limiting control over light intensity.
- Installation should be performed by a qualified electrician if unsure.
- Fixed dimensions may not fit all existing fixtures without modification.
Setup, Compatibility & Care
Setup: This LED 2D bulb is designed as a direct replacement for 28W CFL GR10Q 4-pin bulbs. Crucially, the existing ballast must be removed from the light fixture before installing the LED bulb. Wiring should be connected directly to the mains. Users should ensure they are using the correct voltage (220-240V) and wattage (12W) for their application. If you are unsure about any part of the installation process, it is strongly recommended to consult a qualified electrical engineer.
Compatibility: This bulb uses the GR10q 4-pin cap and is compatible with fixtures designed for 2D fluorescent lamps, provided the ballast is removed. It is not dimmable.
Care: To maintain performance, periodically clean the bulb and fixture with a dry or slightly damp, soft cloth. Ensure the power is switched off at the mains before cleaning.
