How to choose a bedside lamp for a Bangladeshi bedroom

A bedside lamp is the one light in the house you use while half asleep, so it is worth more thought than it usually gets. Most of the advice written about them online assumes a Western bedroom — a big nightstand, a cool climate, and mains power that never goes out. Here is the version that applies here.

Get the height right first

The rule that matters: when you are sitting up in bed, the bottom of the shade should be roughly at eye level. Too high and the bulb glares straight into your eyes when you reach for the switch. Too low and the lamp lights the table instead of your book.

In practice that means a bedside lamp is usually between 35 and 50 cm tall, measured from the table, and the table itself is usually 55 to 65 cm off the floor. Measure your own table before you buy anything — bed heights vary far more than lamp heights do.

If your nightstand is narrow, which is common in Dhaka flats, look for something with a small footprint rather than something short. Our Dune Arch is the flattest thing we make and will sit on a shelf barely wider than a phone.

Warm light, not bright light

The number to look at on an LED box is the colour temperature in kelvin, and for a bedroom you want 2700K to 3000K, sold as "warm white". The 4000K and 6500K bulbs common here are daylight and cool white — they are correct for a kitchen or a study and wrong for a bedroom, because that blue-leaning light is exactly what tells your body it is still daytime.

Brightness matters less than people expect. For bedside reading, 400 to 600 lumens is plenty; that is a 5 to 7 watt LED. Anything brighter and you will end up not using the lamp at night, which is the whole point of it.

This is also where a printed shade earns its place. Because the light passes through the printed wall, the pattern is projected onto the wall and ceiling rather than just sitting on the lamp. Our bedside pieces are designed around that — the Terra Crescent inverts its own pattern when it is lit.

Heat is the thing people get wrong

3D printed lamps are printed in PLA, a plant-based plastic. It is a good material for this — rigid, takes fine detail, no smell — but it softens at temperatures a filament or halogen bulb reaches easily.

So: LED only, always. A modern LED runs cool enough to sit inside a printed shade indefinitely. An old incandescent bulb will slowly deform the print, and no replacement policy covers that. We ship an LED already fitted for exactly this reason.

The same property is why a printed lamp should not live on a windowsill that gets direct afternoon sun. A Bangladeshi summer window is hot enough to sag a print on its own, with the lamp switched off. Anywhere else indoors is fine. We go into this in more detail in are 3D printed lamps safe?

Think about load shedding before you buy

If the power in your area is unreliable, a mains-only bedside lamp is the first thing to become useless at the worst moment. Two practical options:

• A USB-powered lamp, which will run off any power bank you already own. Our Dune Arch runs off USB for this reason.
• A mains lamp on an IPS circuit, if your flat has one wired to the bedroom.

It is a small decision that changes how much you actually use the lamp.

Scale it to the room

The common mistake in a small bedroom is a lamp that is technically correct but visually too heavy. A large sculptural piece like the Coral Bloom is meant to be the thing you look at in a room, and on a crowded nightstand next to a phone, a glass of water and a charger, it will simply feel crowded.

If the nightstand is doing three other jobs, pick something vertical and narrow — the Vortex or the Petal Pleat. Save the big pieces for a sideboard or a corner table where they have room to be seen.

A short checklist

• Shade bottom near eye level when sitting up
• 2700K–3000K warm white, 400–600 lumens
• LED only, never filament or halogen
• Not on a sunlit windowsill
• USB or IPS if load shedding is a problem where you live
• Footprint that fits what is already on the table
