£3.75

The Loadstar Heavy Duty Lighting Timer is a 24-hour segmental mechanical timer designed to handle the high starting load produced by a single compatible 600W HID lighting ballast.

Purpose-built for lighting control, the Loadstar timer provides a straightforward way to automate daily light and dark periods without requiring a separate contactor when operating 1 x 600W HID ballast.

The mechanical dial operates over a repeating 24-hour cycle and is divided into 15-minute timing intervals. This provides 96 individual switching segments across each day, allowing the required lighting period to be set quickly and easily.

Once configured, the selected schedule repeats every 24 hours, making the Loadstar Heavy Duty Timer a practical solution for single-light installations requiring consistent automatic control.

Why choose the Loadstar Heavy Duty Lighting Timer?

  • Designed for HID lighting - built to handle the demanding starting load associated with a compatible HID ballast.

  • No separate contactor required - the specified single 600W HID ballast can be controlled directly.
  • 24-hour automatic control - creates a repeating daily lighting schedule.
  • 15-minute intervals - provides flexible adjustment of lighting on and off periods.
  • 96 switching segments - quarter-hour adjustment throughout the full 24-hour cycle.
  • Simple mechanical programming - no digital menus, apps or complicated configuration.
  • Ideal for single-light installations - straightforward automatic control without installing a larger multi-way lighting controller.
  • 12-month manufacturer warranty - supplied with a 12-month manufacturer warranty.

Automatic 24-hour lighting control

Consistent light and dark periods are an important part of managing many crops under artificial lighting. The Loadstar Heavy Duty Timer automates this process, removing the need to manually switch the lighting system at the beginning and end of each cycle.

The timer dial represents a complete 24-hour period and is divided into 15-minute segments. These segments are used to select when the connected lighting system should operate.

Once the current time and required operating periods have been set, the timer progresses through the programme and repeats the same schedule each day.

Designed for the demands of HID lighting

HID lighting places particular demands on switching equipment. When an HID ballast starts, its electrical characteristics can place considerably more stress on timer contacts than would be expected from looking at running wattage alone.

For this reason, a standard household timer should not automatically be assumed suitable for controlling an HID ballast simply because its stated wattage rating appears high enough.

The Loadstar Heavy Duty Lighting Timer is specifically designed to control a single compatible 600W HID ballast, allowing the ballast to be switched directly without requiring a separate contactor for this specified application.

Ideal for single 600W HID lighting systems

The Loadstar timer is particularly suited to installations where one compatible 600W HID lighting system needs to operate on a consistent daily schedule.

It provides a compact and straightforward alternative to a larger multi-way lighting control system where only one ballast needs to be controlled.

For installations using several HID ballasts, an appropriately rated multi-way lighting contactor or dedicated lighting controller should be used instead of attempting to switch multiple ballasts through a single timer.

Simple 15-minute segment programming

The mechanical dial is divided into 96 individual 15-minute segments. These segments allow the required operating periods to be selected directly on the timer.

This makes it suitable for commonly used daily lighting schedules as well as custom programmes that operate in quarter-hour increments.

Mechanical programming also makes the timer easy to check at a glance. The selected operating periods are visible directly around the dial without needing to navigate menus or access a separate controller.

Setting up the Loadstar Heavy Duty Timer

  • Set the mechanical dial to the correct current time.
  • Select the required operating period using the 15-minute segments.
  • Connect one compatible 600W HID ballast to the timer.
  • Connect the timer to the appropriate mains supply.
  • Check that the lighting switches on and off at the intended times.
  • Periodically check that the timer remains set to the correct current time.

Always follow the instructions supplied with the timer and the electrical requirements specified by the manufacturer of the connected ballast and lighting equipment.

Lighting timer safety & load management

The Loadstar Heavy Duty Lighting Timer is specified for one compatible 600W HID ballast. Its suitability for this application should not be interpreted as approval for multiple ballasts or other high-load electrical equipment.

  • Use with no more than 1 x compatible 600W HID ballast for the stated application.
  • Do not connect multiple HID ballasts to the timer.
  • Use appropriately rated lighting control equipment for multi-light installations.
  • Keep the timer and electrical connections protected from water and excessive moisture.
  • Do not use the timer if the plug, socket, cable or housing shows signs of damage.
  • Keep the timer accessible for routine inspection.
  • Follow the electrical requirements of the connected ballast and lighting system.

Loadstar Heavy Duty Lighting Timer FAQs

What is a heavy-duty lighting timer?

A heavy-duty lighting timer is designed to switch electrical loads that can place greater stress on timer contacts than ordinary household appliances. This Loadstar model is specifically designed for controlling a single compatible 600W HID ballast.

What is the maximum HID lighting load for this timer?

The Loadstar Heavy Duty Lighting Timer is designed to control 1 x 600W HID ballast. Larger or multi-light installations should use appropriately rated lighting control equipment.

How accurately can I set the lighting times?

The mechanical dial is divided into 15-minute intervals, allowing switching times to be adjusted in quarter-hour increments across the 24-hour period.

Can I set more than one on and off period during the day?

Yes. The segmental dial allows multiple operating periods to be selected within the same 24-hour cycle, provided the required switching times follow the timer's 15-minute intervals.

Does the timer need programming every day?

No. Once the current time and required operating segments have been set, the mechanical programme repeats on a 24-hour cycle.

Will the timer keep the correct time during a power cut?

The mechanical clock relies on the mains supply to advance, so a power interruption can leave the timer behind the actual time. Check and correct the dial following a power cut where necessary.

Can I use this instead of a lighting contactor?

For the specified application of controlling a single compatible 600W HID ballast, the timer is designed to operate without a separate contactor. Multi-light installations require appropriately rated control equipment.

Can I use the timer for an 18/6 or 12/12 lighting schedule?

Yes. The 24-hour segmental dial can be configured for commonly used daily schedules such as 18 hours on / 6 hours off or 12 hours on / 12 hours off.

What is the advantage of a mechanical timer over a digital timer?

A mechanical timer is particularly straightforward where the same schedule is required every day. Switching periods are set directly on the dial, making the programme easy to view and adjust without navigating digital menus.

Where should the Loadstar timer be installed?

Install the timer in a suitable dry location where it and its electrical connections are protected from water, irrigation spray and excessive moisture while remaining accessible for inspection.

Should I check a mechanical lighting timer regularly?

Yes. Periodically check that the dial shows the correct current time, the required segments remain correctly set and the timer, plug and socket show no signs of damage or overheating.

How many Loadstar Heavy Duty Lighting Timers are in an outer case?

The outer case quantity is 50 timers.
