The lampshade bottom should sit roughly even with your chin when you're sitting up in bed — typically 24-28 inches total lamp height for a standard 25-inch nightstand. If you read in bed, prioritize an adjustable arm or gooseneck design that aims light at the page, not your face.

A dedicated reading lamp needs 800-1100 lumens at the page (roughly a 60-75W incandescent equivalent or a 10-12W LED). Color temperature around 3500-4000K reduces eye strain better than the typical warm-white 2700K of living-room lamps.

Touch lamps are great for bedside tables (no fumbling for a switch in the dark) but they're sensitive to power surges and can wear out the dimmer module in 3-5 years. Smart bulbs with a Wi-Fi-controlled regular lamp give you the same convenience with a longer lifespan.
