Push-up mast work light
A tripod or trolley-mounted floodlight on a manually extended mast, moved by one person and plugged into the nearest socket. The unit that actually lights the task rather than the site.
Features
- A manual mast has no winch, gearbox or cable to fail, which is why these units survive being thrown in a van daily.
- Height is limited to roughly 2 to 4 m, so the unit lights a work face rather than an area.
- Fittings are built for one supply voltage: 230 V single-phase from a site board is the normal case, and a unit wound for a reduced-voltage transformer supply will not run from a 230 V socket.
- Trailing cable is the failure point and the trip hazard, so length and cable protection matter more than the fitting.
- Two heads on one mast let the light be split between a work face and an access route.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Luminous flux | 10 000 - 60 000 | lm | Sized to a task, not an area. |
| Supply voltage | 230 / 1~ | V | Must match the supply it will be plugged into; a transformer-fed unit is a different order. |
| Mast height | 1.8 - 4.0 | m | Task lighting height, not area lighting. |
| Power draw | 100 - 500 | W | Several units run from one socket. |
| Weight | 6 - 22 | kg | Decides whether one person carries it. |
