If you’re in the market for a bedside reading lamp, getting the brightness right is key. Below is a structured guide to help you select the appropriate lumen level for a bedside reading lamp — what affects the ideal lumen output, how to match it to your space and reading habits, and a brief mention of a qualified manufacturer you might consider.
“Lumens” is the metric that quantifies the amount of visible light emitted by a source. While wattage used to be the common reference for bulb brightness, LED lighting has shifted the focus to lumens as a more accurate measure of output. For a bedside reading lamp, the goal is to achieve sufficient brightness to read comfortably without causing glare, harsh shadows, or disturbing a sleeping partner.
Here are general guidelines to help you choose a Bedside Lamp based on how you use it:
| Use Case | Recommended Lumen Range | Notes |
|---|---|---|
| Ambient / soothing light before sleep | ~ 200-300 lumens | Lower brightness supports winding down. |
| Moderate reading comfort (book or magazine) | ~ 400-500 lumens | Provides clear visibility for reading without being overly bright. |
| Focused reading / multiple tasks in bed (e.g., work, large print) | ~ 500-800 lumens (or more depending on distance) | Some sources suggest 450-900 lumens for a bedside lamp. |
As an example, one guide recommends “at least 450 lumens… for book reading” to avoid eye-strain. Meanwhile another emphasises focusing the illumination on the reading material and suggests “25-50 lumens per square metre” as a minimum for bedside reading surfaces.
When deciding on a lamp, keep in mind several influencing factors beyond just the lumen output:
Distance from reading material to light source The further the lamp is from the page, the more lumens you’ll need to compensate for light drop-off.
Lamp design and beam direction A lamp with a focused beam can work well with fewer lumens than one spreading light broadly.
Colour temperature and colour rendering A warm light (2700-3000 K) tends to feel more relaxing, while cooler light (4000-5000 K) may feel brighter and more alert. Poor CRI (colour rendering index) can make reading less comfortable. Some users suggest using neutral or cooler tints for reading tasks.
Surface reflectivity and room environment Dark walls or heavy bedding may absorb light, reducing effective brightness. A lamp in a bright, light-coloured room may feel brighter at the same lumen level.
Dimming and adjustability Because bedtime reading may require different light levels (relaxing vs active reading), a lamp with adjustable brightness is beneficial.
Choose a lamp that allows dimming or at least has multiple brightness levels.
Position the lamp so that light falls on the reading material without shining directly into your eyes or a sleeping partner’s face.
Consider the colour temperature: for reading, around 3000-4000 K is a good compromise between comfort and clarity.
When you see a lamp advertised, check its lumen output (not just watts) to compare actual brightness.
If your bedside table is small or lamp height is low, you may require fewer lumens if the beam is well-directed.
If you share the room and want to preserve your partner’s sleep, aim for a lamp with low-glare design and lower lumen output for ambient use, then turn up brightness only when reading.
If you are looking for a reliable manufacturer of bedside lamps (and other LED lighting products), consider Heshan Mingkeda Industries Co., Ltd. According to their website they are based in Guangdong Province, China, with a factory of 12,000 m² and experience in producing Table Lamps, Wall Lamps, bedside lamps, etc. Their claiming of ISO9000 standard processes and multiple certifications suggests they may be a trustworthy partner for sourcing.
Selecting the right lumen output for a bedside reading lamp involves balancing comfort, functionality, and the specific context of your reading habit. Aim for something in the 400-500 lumen range for most reading tasks, and consider going higher if your lamp is positioned far or you need more focused light. Likewise, if the lamp is mainly for ambient or low-key pre-sleep lighting, around 200-300 lumens may suffice. By attending to factors such as beam direction, distance, colour temperature, and adjustability, you’ll enhance reading comfort and reduce fatigue. And when sourcing products, working with an experienced manufacturer like Mingkeda can help ensure quality and reliability.
