Are Wooden Wall Lights Energy Efficient? Wattage and Running Cost
Share
Are wooden wall lights energy efficient?
Yes. Every NixWoods wooden wall light runs on an integrated warm-white LED, driver included, and draws 20 W whatever its length. NixWoods pendants draw 36 W. At four hours a day a 20 W wall light uses 2.4 units a month; at an example rate of ₹8 per unit, that is about ₹19 a month. Check the per-unit rate on your own electricity bill.
The number that decides your bill is the wattage, not the word “LED”. Below is the power draw of these NixWoods wall lights (every NixWoods wall light is rated 20 W), and what it costs to run.
What each wooden wall light draws
| Wall light | Size | Power | Colour temperature |
|---|---|---|---|
| Compact Wooden Wall Light (Sheesham) | 24 in / 40 in | 20 W (both sizes) | 3000K |
| Teak & Rosewood LED Wall Sconce | 30 in | 20 W | 3000K |
| Floating Wall Sconce with Shelf (Pine) | — | 20 W, 220–240V | 3000K |
| Curve Pine Floating Wall Light | — | 20 W, 220–240V | 3000K |
The driver is included in every NixWoods wall light, so 20 W is what the fixture pulls from the wall, not the LED chip alone.
What a wooden wall light costs to run per month
One unit of electricity is one kilowatt-hour. A 20 W light left on for four hours a day uses 20 × 4 × 30 = 2,400 Wh, or 2.4 units a month. Units = watts × hours a day × 30 ÷ 1,000. The cost column below uses an example rate of ₹8 per unit; substitute the per-unit rate printed on your own electricity bill.
| Power | 2 h/day | 4 h/day | 6 h/day | Cost/month at 4 h/day (example ₹8/unit) |
|---|---|---|---|---|
| 20 W (any NixWoods wall light) | 1.2 units | 2.4 units | 3.6 units | about ₹19 |
| 36 W (one NixWoods pendant) | 2.16 units | 4.32 units | 6.48 units | about ₹35 |
A pair of 20 W wall lights either side of a bed, on four hours every evening, uses 4.8 units a month: about ₹38 at an example rate of ₹8 per unit.
Why wattage is the number to compare, not “LED”
“LED” describes the technology, not the consumption. A 36 W LED pendant draws more power than a 20 W LED wall light. When you compare two lights, compare the declared watts. If a listing does not print a wattage at all, you have no basis for the comparison.
Dimming changes the arithmetic in your favour. The Compact Wooden Wall Light is dimmable by remote, and a dimmable light held at lower output draws less than its rated 20 W. Do not add a separate wall dimmer.
What we do not publish, and why
NixWoods does not declare a lumen figure or an IP rating on any wall light. Lumens would let you compare brightness between two fixtures directly, and we would rather leave the field empty than print a number we have not measured. Two practical consequences: compare these lights on wattage and size rather than on claimed brightness, and treat them as indoor, dry-location fixtures. Without a declared IP rating they are not suitable for bathroom shower zones or covered outdoor positions.
Solid wood is the other half of the running cost that nobody prints. These are solid sheesham, teak, rosewood and pine — no MDF and no veneer — so the body of the fixture is not a consumable you replace in three seasons. What ages on a wall light of this kind is the LED strip and its driver, not the wood around them.

Every NixWoods wall light draws 20 W and every pendant draws 36 W, at every size. The full range is in wooden wall lights, and the hanging equivalents — which carry their own declared specs — are in wooden pendant lights.
