Their compact double-tube design is efficient for various indoor applications like retail spaces or recessed lighting. If you require a specific voltage or base type not listed, consult a local electrician for compatibility. For those needing standard E27 screw bases, alternative options are available. ## How to use 1. Ensure your light fixture has a G24q-1 4-pin socket and is compatible with electronic or dimming ballasts. Verify the fixture's voltage rating supports India's 220-240V mains or that the bulb is universally compatible. — Check Fixture Compatibility 2. Carefully remove the old bulb. Align the 4 pins of the new Sylvania Dulux D/E CFL bulb with the socket and gently push it in until it clicks securely. Avoid touching the glass with bare hands to prevent oil transfer. — Install the Bulb 3. Turn on the light switch. If you have a compatible dimming system, test the dimming function to adjust the light output.

Check your fixture's base type; this bulb uses a G24q-1 4-pin base. Indian fixtures commonly use E27 screw or B22 bayonet sockets. If your fixture has an E27 socket, you may need a G24q-1 to E27 adapter. Also, verify the bulb's voltage compatibility with India's 220-240V mains, as US bulbs are often 120V. LEDVANCE CFLs may support universal voltage or require a transformer. ### What is the difference between 395nm and 365nm black light bulbs? This product is a 3000K white light CFL bulb, not a black light. Black light bulbs emit UV-A light, typically at 395nm or 365nm wavelengths, used for glowing effects or inspection. This Sylvania Dulux D/E bulb emits visible white light for general illumination, not UV light. ### Are these LEDVANCE bulbs safe for use in India? Yes, these bulbs are designed for safe operation, but voltage compatibility is key. US-based bulbs are typically 120V, while India uses 220-240V. Ensure your fixture or the bulb itself supports this voltage range to prevent damage. All customs duties and GST are pre-paid and included in the listed price, with delivery via ExpressBox tracked shipping. ### How long will these 13W CFL bulbs last in my home? These bulbs have an average rated life of 20,000 hours, which is significantly longer than standard incandescent or many other CFL bulbs. This means fewer replacements and consistent light output, reducing maintenance hassle and costs over time. ### Can I use these bulbs for general home lighting in India? Yes, these 13W CFL bulbs provide 900 lumens of 3000K warm white light, suitable for general indoor illumination in living rooms, bedrooms, or offices. They are dimmable when paired with a compatible electronic dimming ballast, allowing you to adjust the light level as needed. ### What are the benefits of using CFL bulbs over LED bulbs? CFL bulbs like these offer a good balance of energy efficiency and warm white light at a lower upfront cost compared to some LEDs. They are also dimmable with specific ballasts. While LEDs generally offer longer lifespans and lower energy consumption, CFLs remain a cost-effective choice for many applications, especially when dimming is a requirement. ### How do I choose the right light bulb for my Indian fixture? First, identify the base type of your fixture (e.g., E27 screw, B22 bayonet, G24q-1 pin). Then, check the required wattage and voltage compatibility for your region (India uses 220-240V). Consider the desired light color (Kelvin) and brightness (lumens). This Sylvania bulb uses a G24q-1 base and is 13W, 3000K. ## Compliance No product-specific compliance warnings identified. Standard imported-goods terms apply: customs duties & GST paid; for personal use in India; follow the manufacturer's usage instructions on the packaging. ## Images 1. https://images.crowcrowcrow.com/B00PB0JBAO-2.webp --- Source: https://crowcrowcrow.com/p/sylvania-dulux-cfl-fluorescent-light-bulb-pin-13w-2/xux2267 Returns: 14 days, free pickup, full refund on genuine issues.
