Choose desk lighting from the paper tasks you actually do
Use a page, pen and screen together to compare useful light placement, shadows and glare before choosing a lamp arrangement.

Start with the task area
Write down the work that takes you away from the screen: reading printed documents, making handwritten notes, examining small parts or using a drawing pad. Mark where each task takes place on the desktop. OSHA recommends supplemental task lighting for writing and reading while limiting brightness around monitors. A lamp should therefore be assessed against the page or object you need to see, alongside the screen's placement.
Make a simple task sample
Use a typical document, the pen you normally use and a familiar screen window. Place them in your usual working arrangement. Record the time of day, window covering position and other lights that are on. Repeat at the time when the room is most difficult to work in. These observations describe your room; they are not laboratory measurements of a lamp's output or a claimed treatment for eyestrain.
Record shadows as well as brightness
Look at the area covered by your hand while writing and the shadows from nearby objects. Try permitted lamp positions without allowing the lamp to obstruct the page or interfere with the monitor. For each position, note whether the useful light reaches the task and whether a bright light source is directly in your view. Keep brightness control and physical placement as separate columns so that you can see which change helped.
Check the screen at the same time
Observe whether the proposed light reflects from the display or nearby glossy surfaces. OSHA recommends placing task lighting so it does not reflect on the screen. Repeat the check with a typical light and dark screen window, because a reflection that is subtle in one may be obvious in another. If moving the lamp fixes the page but creates a screen reflection, record both results; more output does not resolve the placement conflict.
Compare mounting and control needs
Measure the space available for a lamp base, clamp or monitor attachment using the selected manufacturer's instructions. Record power requirements, cable routing and which controls are reachable while seated. A screen-mounted light and a freestanding task lamp have different attachment and placement constraints. Neither format establishes coverage of your particular paper task from its product photograph alone.
Keep a useful decision record
Create one row for each viable arrangement, with task coverage, hand shadow, screen reflection, attachment fit and control access. Use the worksheet to choose which product specifications and demonstrations to investigate next. Leave uncertain light levels marked unknown if you have no suitable measurement. This practical comparison avoids inventing a universal brightness prescription and makes the eventual purchase depend on the work area you actually use.
