What is the difference between a 395nm and a 365nm black light bulb?

A 395nm bulb is widely available for glow-in-the-dark decor and parties. A 365nm bulb emits purer ultraviolet light for more vivid fluorescence, ideal for inspection. This Sylvania bulb is a standard white light source, not a UV-A or UV-C black light.

Will this Sylvania Dulux D/E bulb fit my Indian light fixture?

This bulb uses a G24q-1 base, which is a 4-pin connector common in electronic ballast fixtures. Indian fixtures often use E27 screw or B22 bayonet sockets. You may need an adapter to fit this bulb into a standard Indian holder. Always check your fixture's socket type before ordering.

How long does this Sylvania CFL bulb last?

This Sylvania Dulux D/E CFL bulb has an average rated life of 20,000 hours. This is significantly longer than standard incandescent bulbs and many other CFLs, meaning fewer replacements and lower maintenance costs over time.

Is this Sylvania bulb dimmable?

Yes, this Sylvania Dulux D/E CFL bulb is designed to be dimmable when paired with an electronic dimming ballast. This allows you to adjust the light intensity to suit your needs and further optimize energy savings.

What is the color temperature and CRI of this bulb?

The bulb emits a soft white 2700K light, providing a warm and natural tone. It features a Color Rendering Index (CRI) of 82, meaning colors appear accurate and true under its light, which is beneficial for retail and accent lighting.

How much energy does this Sylvania CFL bulb save?

This 13W CFL bulb uses approximately one-quarter of the energy of a comparable 60W incandescent bulb, offering up to 75% energy savings. When used with a dimming ballast, energy savings can be even greater.

How to choose a light bulb for India?

When choosing a light bulb for India, confirm voltage compatibility (220-240V) and the base type (E27, B22, or G24q-1) to match your fixture. Consider energy efficiency, lifespan, and light quality (lumens, CRI, color temperature) for your specific needs. This Sylvania bulb is designed for electronic ballasts and offers long life and dimmability.

Are there any side effects of using CFL bulbs?

CFL bulbs contain a small amount of mercury. If a bulb breaks, ensure the room is well-ventilated and avoid direct skin contact. Handle broken bulbs carefully and dispose of them properly according to local regulations. This Sylvania bulb is TCLP and RoHS compliant.
