Their 20,000-hour lifespan drastically cuts down on replacement needs, a significant advantage in India where maintenance can be costly and disruptive. The 4100K cool white light with 82 CRI ensures true color representation, vital for retail spaces or detailed work. Designed for electronic dimming ballasts, these bulbs offer controllable light and substantial energy savings, using only 26W. Imported directly, they meet stringent TCLP and RoHS standards, ensuring quality and safety for your lighting needs. **Ideal for Offices & Retail, Consider Alternatives for Residential Task Lighting** — These bulbs are perfect for commercial applications like office boardrooms, hotel lobbies, retail showcases, and exit signs where long life, dimmability, and consistent light quality are paramount. For residential use, they excel in recessed ceiling fixtures or task lighting requiring cool white illumination. However, if you require warm, ambient light for living spaces or specific color temperatures outside of 4100K, consider warmer-toned LED bulbs. Also, ensure your fixture uses an electronic or dimming ballast; these bulbs are not compatible with magnetic ballasts or standard incandescent sockets. ## How to use 1. Ensure the light switch controlling the fixture is turned OFF before attempting to replace any bulb. This prevents electrical shock and ensures safe installation. — Safety First 2. Carefully unscrew or unclip the old bulb from its socket. If it's a G24q-3 base, it will likely pull straight out. Dispose of the old bulb responsibly. — Remove Old Bulb 3. Align the 4 pins of the Sylvania Dulux D/E CFL bulb with the G24q-3 socket and push gently until it clicks into place. Ensure it is securely seated. — Install New Bulb 4. Turn the light switch back ON. The bulb should illuminate. If your fixture has a dimmer, test its functionality to ensure smooth dimming capabilities. — Test and Dim ## Product details | Field | Value | |---|---| | Light Source | Fluorescent | | Phosphors | Rare earth phosphors | | Compliance | TCLP & RoHS compliant | | Usage | Indoor | | Recommended Fixtures | Recessed downlights, showcase lighting, task lighting, office lighting, hotel lobbies | | Ballast Compatibility | Electronic and dimming ballasts only | | Cost per use | 20,000 hours at ₹3,029 — ₹0.15 per hour | | Shelf life after opening | Not applicable (product is not consumed) | | Reapplication math | N/A (lighting is continuous) | | Contraindications | Not for use with magnetic ballasts, standard incandescent sockets, or in damp/wet locations unless fixture is rated. | | Allergens / common irritants | Contains glass; handle with care. | | Brand | Sylvania (LEDVANCE) | | Model Name | Dulux D/E 20669 | | Part Number | SYL20669 | | Bulb Type | Compact Fluorescent Lamp (CFL) | | Base Type | G24q-3 (4-Pin) | | Bulb Shape | T4 Double Tube | | Wattage | 26W | | Incandescent Equivalent Wattage | 26W (approx. 100W equivalent) | | Voltage | 100-120V (compatible with Indian mains) | | Lumens | 1710 lm | | Color Temperature | 4100K (Cool White) | | Color Rendering Index (CRI) | 82 | | Average Rated Life | 20,000 hours | | Dimmable | Yes (with electronic dimming ballast) | | Material | Glass | | Pack Quantity | 4 bulbs | | Item Weight | 0.4 lbs (approx. 0.18 kg) | | Dimensions | 1.4 x 1.4 x 6.9 inches (approx. 3.5 x 3.5 x 17.5 cm) | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### How to buy an original Sylvania Dulux D/E CFL light bulb in India?
