Poultry House Lighting Guide: Wattage, Spacing and Timer Setup

Lighting in a poultry house is usually planned around wattage per unit area rather than around individual lamps. Once the target density is set, the number of lamps follows from the floor area, and the layout follows from how evenly the light needs to reach the birds.

Spacing is a balance between coverage and cost. Lamps placed too far apart create bright and dim zones, while lamps placed too close together raise both the fixture count and the electrical load. A practical approach is to sketch the house on a grid and place lamps so the overlap between neighbouring fittings is roughly consistent across the house.

Photoperiod, or the number of lit hours per day, is the third variable. Different production stages call for different light schedules, and the schedule should be stable rather than changed at short notice. A programmable timer makes this easier to manage and reduces the chance of human error.

When specifying timers, confirm the switching capacity, the number of on and off events per day, and whether a battery backup is included so the schedule survives a power interruption. Together with the correct wattage and spacing, these settings give a lighting plan that is easier to install and to maintain.
