Good hot desk lighting starts with the screen and seated positions people really use, not one ideal layout. List those positions first. Then run the same glare and work-surface check in each one.
If every position you checked passes, the fixed lighting works for those setups. If one fails, figure out whether the problem is a screen reflection or a dim work area. Then pick the fix that matches that problem.
Map the Screen and Seated Positions the Desk Needs to Support
Your map is the scope of the lighting check. It should cover the setups the desk actually serves, not every arrangement someone might try. The number of setups depends on how the desk is used, so there is no fixed count.
- List the real screen setups. Watch how the desk gets used, or ask the people who book it often. Write down each distinct setup, such as "monitor centered, facing the wall," "monitor angled toward the window," or "laptop only, pushed to the left side."
- Pair each setup with a seated position. Note where the person sits and which way they face. One monitor angle can feel very different from a chair at the end of the desk than from the center.
- Name the usual task area. For each setup, mark where the work happens: the screen alone, or the screen plus a strip of desk for paper, notes, or a keyboard.
- Note the bright sources in view. From that seat, record any window, overhead fixture, or bright wall that sits behind, above, or across from the screen.
A finished entry might read: "Setup B: monitor angled left, user facing the window wall, reads printed plans to the right of the keyboard, ceiling fixture directly overhead." Each setup gets one line like that. This gives the next check a concrete place to start and makes it easy to see which setup a later problem belongs to.
Run the Same Glare and Work-Surface Check in Each Mapped Position
Repeat one short check for every setup on your map, and keep screen results apart from work-surface results. That way, a problem that shows up in only one arrangement gets tied to that arrangement.
OSHA's workstation evaluation checklist asks whether glare from windows or lights is reflected on the screen badly enough to make users squint or sit awkwardly. It also asks whether lighting can be adjusted for different tasks. The step-by-step routine below applies those two questions to a shared desk. It's a practical method, not an OSHA hot-desk protocol.
- Set up one mapped configuration and sit in it. Use the chair position and facing direction from your map, not a standing view.
- Look at the screen for reflections. Check whether a window, fixture, or bright surface shows up on the display and makes it harder to read. The CCOHS glare test gives a simple way to confirm it: from your normal working spot, block the light falling on the task from the front or above. If the details get easier to see, reflections are a problem.
- Check the actual work area. Try the usual task there, such as reading a printout or writing notes. Look for shadows over the work area and anything that's hard to make out.
- Record two separate results. Mark the screen "pass" or "needs attention," then do the same for the work area. Write each result next to that setup's line on the map.
- Move to the next setup and repeat. Keep the same criteria so you can compare results across setups.
You'll end up with a grid of results, such as "Setup A: screen pass, work area pass" and "Setup B: screen needs attention, work area pass." For a second look, the CCOHS office lighting checklist covers monitor readability, local lighting, and glare from windows or overhead lights. Remember that these results apply only to the setups you checked.
Use the Results to Choose a Lighting Approach
Keep the current fixed lighting for the setups you checked if each one passed both the screen check and the work-area check. That all-pass rule is a practical planning guide rather than a universal lighting standard. Save the map so that if the desk layout or screen positions change, you can retest before assuming the setup still works.
When a setup fails, look at which check failed before you change anything. A screen reflection comes from where the screen sits relative to a bright source. So try an allowed change first, such as a different monitor angle or moving the screen away from the window's reflection. Then run that setup's check again. A desk lamp aimed at paperwork doesn't automatically fix a reflection on the display, so don't count on one to do that.
A work-area failure is a different problem. If the screen passes but the desk surface is too dim or shadowed for its usual task, task lighting is worth considering. OSHA's desk-lighting purchasing guidance says lighting needs depend on the task. It also says the location, angle, and intensity of light sources should be adjustable. On a shared desk, that adjustability matters because the next person may sit in a different setup. After adding or moving any light, check the screen again, since the new light can create its own reflection.
Sometimes a failure keeps coming back in the same setup after you've made adjustments. In that case, write down the exact setup and condition, such as "Setup C, overhead reflection on screen." Then decide whether that setup should stay in use or whether the room fixtures need a closer look. If you get to the fixture stage, you can compare room options in our office lighting range or our LED panel lights. It also helps to read about planning a low-glare fixture layout before you choose positions. For a larger floor, a lighting layout design service can help you plan fixtures around the desk zones you mapped.
FAQs
What if only one setup shows a reflection?
Treat it as a problem with that setup, not the whole desk. You have two choices. You can drop that arrangement from the setups the desk is expected to support, or you can change only that screen position and recheck it. There's no need to change lighting that works for every other setup.
Does a laptop-only setup need its own entry on the map?
Yes, if people actually use the desk that way. A laptop screen sits at a different height and angle than a monitor, so it can pick up different bright sources. Give it its own line and check it like any other setup.
Should hot desk lighting be checked at different times of day?
If a window is part of any setup, check that setup at the times people actually book the desk. OSHA's checklist names glare from windows as a separate source of screen reflections, so a check done in one session may not reflect another.
What can a desk user do if a booked setup has glare?
Start with the changes you're allowed to make, such as adjusting the monitor angle or picking another setup the desk supports. Then report the setup and the problem, for example "monitor facing the window, reflection on screen." That gives whoever manages the space a specific setup to fix.
