Work Lights for Packing Sheds and Sorting Tables

For a packing shed or sorting table, buy LED fixtures with enough brightness to light the whole work surface evenly, a high color rendering rating so you can judge ripeness and blemishes, and a water-protection rating that fits a damp room. Then mount them so no one works in their own shadow. The numbers to read on a listing are lumens, color temperature, the color rendering index (CRI) and the IP rating.

This guide explains those four numbers and how to place the lights. It sets no lumen targets, because the right level depends on your room and your task. Fixed wiring and outlets in a wet area belong to a licensed electrician and the maker's manual.

The four numbers on a lighting listing

Lumens and color temperature are on most listings. CRI and IP ratings may be hidden in the specifications, and some listings leave them out. If a fixture does not list CRI or an IP rating, ask the seller or choose a different one.

Brightness and layout

More lumens is not always better, and one bright bulb is worse than several lower ones. A single bright point makes harsh shadows and glare off wet or stainless surfaces. A row of fixtures over the length of the table spreads light and cuts shadows.

• Light the surface, not the room: task light over the table matters more than a bright ceiling.
• Spread it: two or more fixtures per table reduce the shadow of your hands and head.
• Mount in front, not behind: a light above and slightly in front of the worker keeps your own shadow off the work.
• Diffuse it: a frosted lens or a diffuser softens glare. Bare LED strips can sparkle off wet produce.
• Check with a test: hang a fixture temporarily and sort a tray. If you squint, move or diffuse it.

Check listings for a stated lumen output and the beam spread. A light with the right lumens but a narrow beam leaves dark corners. Think about what else sits in the room: a stainless table reflects light, and the stainless work table guide notes what to check on those surfaces, including sheen.

Color temperature and color rendering

Color temperature describes whether the light looks warm (yellowish) or cool (bluish). It is about appearance, not about how well colors show. That is the job of CRI, the color rendering index. According to Wikipedia's article on the index, the highest possible value is 100, which is given to a source whose spectrum matches daylight, and typical white LEDs reach 80 or more, with some makers claiming up to 98. The same article says a high CRI alone does not guarantee good color rendition and that newer measures such as IES TM-30 are replacing CRI among professional lighting designers.

For a packing table, what you want is simple. Pick lights with a high CRI listed by the maker and a single color temperature across the room. Then check a few items under the light: the color of a ripe versus unripe fruit, the edge of a bruise or a pale leaf. If you can tell them apart under the light, it is doing its job. The article says CRI is not a good indicator for assessing sources below 5000 K, which is a reminder that a number does not replace looking at real produce under the light.

Wet and damp locations

Packing sheds are damp: wash-down spray, condensation and humid air. A fixture needs a water-protection rating to match. The usual rating on a listing is the IP code, defined in IEC 60529, which Wikipedia's article on the IP code describes. It has two digits: the first covers solid objects and dust, from 0 to 6, and the second covers water, from 0 to 9. An X replaces a digit when it was not rated.

• IPX4: protected against splashing water from any direction.
• IPX5: protected against water jets from any direction. This is a more demanding rating than splash.
• IPX7: protected against immersion at a depth the maker specifies. The article notes that water ratings above IPX6 do not automatically include the lower ones, so look at the exact wording.
• IP65: dust-tight (6) and protected against water jets (5). It does not cover immersion.

Which one you need depends on where the fixture hangs. A light above a table that is hosed down needs more than a light on a ceiling away from water. The IP code is a rating of the enclosure, so it does not replace a wet-location or damp-location listing on the label. Look for the listing mark and wording in the manual, and ask a licensed electrician about outlets, cords and any fixed wiring in a wet room.

Types of fixtures

• Linkable LED shop lights: long fixtures that hang over a table. Check how many can be linked and whether the cords are long enough.
• LED strips and bars: slim and easy to mount under shelves. Check the housing, cover and cleanability.
• Clamp and flexible-arm lights: useful for a sorting station you move around. Check clamp grip and cord length.
• Magnetic or rechargeable task lights: handy for inspection and for power outages. Check battery care in the manual.
• Headlamps: good for early harvests and loading before sunrise. Check how comfortable they are with a hat.

Power, cords and safety

Lights in a packing shed share the room with water, so power layout is part of the plan. Keep plugs, power strips and extension cords away from wash areas, and do not run cords across wet floors. Follow the manual for each fixture, including mounting and any limits on linking. If you are adding outlets or fixed fixtures, hire a licensed electrician who knows local code.

• Use fixtures whose labels match the dampness of the spot.
• Mount fixtures securely, since a falling fixture over a work table is a hazard.
• Keep spare lamps or fixtures on hand for busy weeks.
• In an unheated shed, check the maker's notes on cold-weather use; the winter packing shed guide discusses cold-weather gear.
• Check that the fixtures suit the cover or lens you need over open produce; ask your food regulator whether shielding is required in your area.

Comfort matters too. Standing under good light for hours is easier if your feet are comfortable; see the anti-fatigue mat guide. If you weigh produce at the same table, glare on a scale display is a common annoyance, so check angles using the bench scale guide as a reference for scale types.
