FAQs
What does G24q-1 fitting mean?
G24q-1 refers to the base type of the bulb, which has four pins arranged in a specific way, designed to fit into a corresponding socket in your light fixture. It's crucial to match this fitting type when purchasing replacement bulbs.
Is this bulb suitable for outdoor use?
This bulb is generally intended for indoor use. Outdoor fixtures must provide adequate protection from moisture and extreme temperatures for CFL bulbs to operate safely and effectively.
How long does this bulb typically last?
The Osram DULUX CFL bulb has an average rated lifespan of 20,000 hours, significantly longer than traditional incandescent bulbs.
Can I use this bulb with any dimmer switch?
While the bulb is dimmable, it requires compatibility with both the dimmer switch and the fixture's electronic control gear. It's recommended to use dimmers specifically designed for fluorescent or CFL lighting.
What is the color temperature of this bulb?
The color temperature is 4000 Kelvin (K), which is classified as cool white. This provides a crisp and neutral light.
How is this bulb more energy-efficient than older bulbs?
CFL bulbs use fluorescent technology, which is inherently more efficient at converting electricity into light than incandescent filaments. This 10W bulb produces the same amount of light (600 lumens) as a much higher wattage incandescent bulb.
What should I do if the bulb breaks?
If a CFL bulb breaks, ventilate the room for 15-20 minutes. Carefully clean up the fragments using a brush and dustpan, avoiding a vacuum cleaner. Wipe the area with a damp cloth. Seal the fragments and cleaning materials in a plastic bag and dispose of them according to local hazardous waste regulations, as CFLs contain mercury.
Troubleshooting
Bulb does not light up
Ensure the bulb is correctly seated in the G24q-1 socket. Verify that the light fixture has power and that the circuit breaker is not tripped. Check if the control gear in the fixture is functioning correctly.
Bulb flickers
This can sometimes indicate an issue with the control gear or a loose connection. Ensure the bulb is fully inserted and that the control gear is compatible and in good working order. If flickering persists, consider replacing the control gear or the bulb.
Dimming not working or not smooth
Confirm that both the bulb and the light fixture's control gear are rated as dimmable. Ensure you are using a compatible dimmer switch. Check all connections and consult the fixture's manual for specific dimming compatibility.
Light output is low
Allow the bulb a few minutes to reach full brightness, as CFLs may require a short warm-up period. Check if the bulb is operating at its full rated wattage and that the control gear is functioning correctly.

- Good color rendering index ensures accurate color perception.
Cons
- Requires a specific G24q-1, 4-pin fixture, limiting compatibility.

Setup, Compatibility & Care
Setup: Ensure the power supply to the light fixture is switched off before attempting to replace the bulb. Carefully remove the old bulb and gently insert the Osram DULUX CFL into the G24q-1, 4-pin socket, ensuring it is securely seated. Turn on the power supply. This bulb is designed to work with electronic control gear; ensure your fixture is equipped with compatible gear for optimal performance and dimming.
Compatibility: This bulb requires a light fixture with a G24q-1, 4-pin base. It is compatible with dimmable systems; however, for dimming to function, both the bulb and the fixture's control gear must be designed for dimming. Using it in a non-dimmable fixture will result in full brightness only.
Care: To clean the bulb, first ensure the power is off and the bulb is cool. Wipe gently with a dry or slightly damp soft cloth. Avoid using abrasive cleaners or solvents. As this is a fluorescent bulb, it contains a small amount of mercury. Do not dispose of it in regular household waste; please refer to local regulations for proper disposal of fluorescent lamps.
