The summary
- What you receive: two self-locking pulleys with their cord and their two hooks.
- What they carry: up to 40 kg per pulley, well beyond the weight of an LED bar.
- What they are for: raising the lamp as your plants grow, without a stepladder or a second pair of hands.
- What to plan for: a solid anchor point, independent of the grow bed.
- The length: 2.4 m of cord, enough to hang a lamp from a ceiling.
- How it arrives: a lightweight parcel, sent with the rest of your order.
Pair of self-locking pulleys for adjusting the height of a light fitting
This hanging system for LED light bars is a pack of two self-locking pulleys that adjust the height of a horticultural lamp with one hand as the plants grow. Each pulley holds up to 40 kg and its cord is 2.4 m long. You will need a solid anchor point, independent of the grow bed.
The height of a horticultural lamp has to be adjusted throughout the crop: as the plants grow, the distance between the lamp and the top of the foliage shrinks, and the light has to be raised to restore it. These two pulleys make that possible with one hand: you pull the free end of the rope, release it, and the mechanism locks the rope at the height reached.
⚙️ Two self-locking pulleys
Each pulley carries up to 40 kg, and its 2.4 m cord lets you hang a light fitting from a room ceiling or from the top bar of a grow tent. Inside the housing, a ratchet mechanism lets the rope slide in the direction of pull and locks it as soon as you let go. To lower the lamp, you release the lock with the lever on the housing and let the rope run through while holding it back. The height can therefore be adjusted continuously, with no notches or knots to retie, and the whole set hangs without tools, with a nylon cord and steel hooks.
🪝 The anchor point
The anchor point matters as much as the pulleys, since it is what carries the lamp throughout the whole crop. A light hung from the frame of a grow bed moves with it on the day you shift the tank or empty it for maintenance, whereas an anchor fixed to the structure of the room stays put. So choose a beam, a rail fixed to the ceiling or the top bar of a grow tent, and check that the loose end of the rope hangs without rubbing against an upright.
A freestanding structure
Hang them from a tent bar, a beam or a ceiling rail, never from the grow bed, which gets moved and emptied.
Two points, not one
Fit a pulley at each end of the bar so that it stays level while you adjust it.
A clear cord
The free end must hang loose, without rubbing against an upright or passing behind a pipe.
Above the water
Form a loop in the electric cable below the level of the socket, so that water runs down to the lowest point.
Two pulleys per light fitting
One pack equips one bar. If you are installing several bars in a row above a table, allow one pack per bar, so that you can adjust each one without touching the others. This is what lets you keep two growth stages at two different heights on the same table.
Adjustment is done with the lamp switched off
A bar that is switched on is hot and dazzling at the very moment you look up at it. Cut the power, wait for the housing to cool to lukewarm, then adjust. While you are at it, check that both pulleys are at the same height: a bar hanging at an angle lights the two ends of the row unevenly.
📏 Height during cultivation
An LED bar spreads its light wider the higher it is, but each leaf then receives less; brought closer, it concentrates the light on a smaller area. Adjustment therefore means keeping a constant distance between the lamp and the top of the plants, raising the bar as they grow. With a 95 cm bar covering up to 1 m², you start from a height that lights the whole growing area, then adjust as soon as the foliage gets close to it. Leaves at the top that curl up indicate a lamp that is too close, while stems that stretch and lean towards it indicate a lamp that is too high.
💧 Above a water tank
In indoor aquaponics or hydroponics, the lamp is hung above a tray where the air stays humid, and electricity sits alongside water. An LED bar rated IP20, like the flowering bar in the catalogue, has no protection against water: keep it out of reach of splashes. A loop in the cable below the level of the socket makes condensation running down the wire drip to the floor instead of carrying it to the plug. The nylon cord should be checked at the end of each crop: humidity and rubbing against an upright eventually wear it down, and a frayed cord should be replaced before it gives way. The guide to setting up your indoor seedling area and the one on getting started with indoor hydroponics detail the complete installation.
