What makes Deltalite LED bulbs better than cheap market bulbs?

Most cheap market LED bulbs use low-grade chips and poor-quality drivers that fail within months. Deltalite uses Grade-A LED chips with a constant-current driver circuit that maintains stable brightness over the bulb's full life. Our bulbs are also tested for voltage surge resistance — critical in Pakistan where power fluctuations can instantly destroy low-quality bulbs.

How long do Deltalite LED bulbs last?

Deltalite LED bulbs are rated for 25,000 hours. At 8 hours of daily use that equals over 8 years. Compare this to incandescent bulbs (1,000 hours) or cheap market LEDs that often fail within 6–12 months. Our 1-year replacement warranty covers any defects in that period.

What wattage LED bulb should I use to replace my old bulb?

LED bulbs produce much more light per watt than older bulbs. Use this as a guide: replace a 60W incandescent with a 7W–9W LED, replace a 100W incandescent with a 12W–15W LED, replace a 40W CFL with a 7W LED. You get the same brightness at a fraction of the electricity cost.

Do Deltalite LED bulbs work with all standard fittings in Pakistan?

Yes. Deltalite LED bulbs come in the standard E27 screw base (most common in Pakistani homes) and B22 bayonet base (used in older fittings). They also work with ceiling fans that have a bulb socket. No adapters or rewiring required.

Which is better — warm white, cool white, or daylight for home use?

Warm white (2700K–3000K) creates a soft, cozy glow — best for bedrooms and lounge areas. Cool white (6000K–6500K) is bright and clinical — best for kitchens, bathrooms, and study rooms. Daylight (5000K) is close to natural sunlight and popular for reading areas and home offices. All three are available in Deltalite bulbs.

How much can I save on my bijli ka bill by switching to Deltalite bulbs?

A typical Pakistani home with 15 bulbs running 5 hours a day uses about 100 units per month on lighting alone if using 60W incandescent bulbs. Switching to 9W Deltalite LEDs reduces this to about 15 units — saving 85 units or roughly PKR 4,000–5,000 per month depending on your electricity tariff.
