LED Light Installation in Surat

Lumens matter, watts do not

Wattage told you something useful when every bulb was a filament. With LED it only tells you how much power the fitting draws. Brightness is measured in lumens, and two 9-watt LED bulbs from different makers can differ by a third in actual output.

As a rough guide, a bedroom is comfortable at around 100 to 150 lumens per square metre, a living room a little higher, and a kitchen counter or study desk needs noticeably more. We work from the room rather than from a number on a box.

• Bedrooms: warm white around 2700–3000K for a restful feel
• Living rooms: 3000–4000K, layered rather than one bright source
• Kitchens and study areas: 4000K with focused task light where it is needed
• Bathrooms: 4000K with fittings rated for damp conditions
• Keep one colour temperature per room — mixed light looks wrong immediately

Why cheap LEDs fail early

An LED chip will run for years. The driver behind it often will not. Most premature failures we replace are driver failures, usually caused by heat with no path out of a sealed fitting or by a driver built down to a price.

Voltage fluctuation is the other common killer, and it is a real factor in parts of Surat. A fitting with a decent wide-range driver survives that; a bargain one does not. We would rather fit fewer, better lights than come back to replace cheap ones every season.

Converting existing fittings

Old tube light fittings can often be converted rather than thrown away, which keeps a familiar fitting and avoids new holes in the ceiling. The starter and choke are removed and the tube holders rewired for a direct-supply LED tube.

That conversion has to be done properly — a half-converted fitting with the choke left in circuit is a fire risk and will shorten the tube's life. We do the full conversion or we fit a new unit; we do not leave it halfway.
