What to check before buying

• Colour temperature (warm, neutral or cool white) and colour rendering index (CRI) for retail and clinics.
• BIS certification for LED products and BEE star ratings where applicable.
• Driver quality, flicker, power factor and surge protection.
• Ingress protection for outdoor use, such as IP65 for floodlights.
• Warranty period and replacement terms, and GST invoice. Ask for photometric data on larger orders.

Frequently asked questions

How many lumens per square foot does an office need?

A general guide is around 300 to 500 lux at desk level. A lighting calculation with room size and fitting spacing gives a precise count.

Which colour temperature should I choose?

Cool white (around 6500 K) suits workplaces and warehouses; neutral (4000 K) suits retail and clinics; warm white suits hotels and homes.

What floodlight wattage for a courtyard?

For small yards, 50 to 100 watts at a pole or wall height of several metres. Larger areas need higher wattages or multiple lights.
