Choosing light towers for your site: battery, diesel or a combined setup

Start with the areas that need light

Mark the places where people will work, walk or gather. A repair point, access route and wider working area need separate consideration.

Use the short lighting enquiry with the job, location and timing; choose Not sure yet for unknown answers. Then follow the question you need to resolve:

• Power and placement: compare battery, diesel or separate units.
• A model has been suggested: read the ratings on the same basis.
• Running costs: compare charging and diesel fuel costs.
• Budget or purchase: use the rental and new-purchase routes.

HSE’s Lighting at work separates task illumination, glare and changes between adjacent areas. This is general UK guidance, not a Malaysian outdoor lighting specification. HSE, printed p. 7

Use the zone sketch to label approximate dimensions, obstacles and existing lights on your photo. Positions and quantities need assessment from the actual site.

Battery, diesel, or both?

Assess the power source for each zone. NIOSH identifies engine-exhaust carbon monoxide as a workplace hazard and recommends considering electric or battery alternatives where possible. Do not run engine-powered equipment in enclosed or partially enclosed spaces. Outdoor placement still needs an assessment of exhaust and nearby air intakes. NIOSH guidance

A diesel tower can be assessed for a separate open outdoor zone. The Yanmar LB430F-1 sheet identifies an L70 engine and four 400 W Metal Halide lamps; it does not establish suitability for every position. Yanmar, p. 1

A combined setup means separate battery and diesel units serving different areas, not one hybrid machine.

Work point / tentAssess the task and battery option.

Pedestrian routeCheck gaps, glare and obstacles.

Open service areaAssess diesel placement and exhaust.

Battery models can also be combined. Ask what extra height, output or battery capacity changes for each task, then compare the proposed packages.

Read the ratings on the same basis

Height, lumens and weight describe different properties. Check the exact variant and measurement basis in these supplied-catalogue examples.

KMC500 has a higher listed lighting position; HRZ-322 has a lower fitting-only weight. Ask whether the task needs that height and how the equipment will get there. Neither establishes an illuminated area. Batteries add weight. KMC500, p. 13, HRZ-322, p. 7

Separate daily hours from the hire period

Give hire dates and operating hours per day separately. A week’s rental does not specify nightly use. For purchase, describe the usual and longest expected shifts.

The KMC500 catalogue’s over-20-hour rating specifies Standard mode with three D24-500 packs. Do not read it as maximum brightness for that period. KMC500, p. 13

The HRZ-322 brochure states over 10 hours at high output; confirm the packs and setting for the quoted unit. It is not an overnight guarantee for every package. HRZ-322, p. 7

Ask for the brightness setting, included packs and charging or spare-pack plan alongside proposed operating hours.

Compare charging and diesel costs

Use the battery vs diesel tower light calculator to compare runtime, charging costs and diesel fuel costs for the same nightly hours. Enter the selected package’s battery capacity, actual lighting draw, electricity tariff and diesel consumption. The initial figures are generic examples; rental, purchase and other ownership costs need separate quotations.

Check the route into the site

Show the loading point and route to each position, including steps, narrow entrances, soft ground and vehicle restrictions. Confirm unloading and movement before booking.

The KMC500 catalogue distinguishes one-person positioning from lifting: its note calls for two or more people to lift it unless a forklift is available. “Portable” should not be read as “one person can lift it.” KMC500, p. 12

Use the exact unit’s manual and site assessment for setup. These catalogues do not establish wind limits, ground requirements or a complete operating procedure.

Choose the rental or purchase route

For rental, use the tower-light rental range and price guides. Estimates depend on the model, condition, battery/charger package and availability; delivery and collection are separate. Agree the period and transport scope.

For new purchase, compare the new tower-light range, including KMC500 and HRZ-322. Confirm the supplied variant, battery/charger package, quantity and lead time. Yanmar remains a rental/secondhand enquiry; discuss its actual condition and availability through the secondhand enquiry page. Hire estimates are not purchase prices.

What to send with your enquiry

Send these details when available:

• Rental or purchase: include the hire period if renting.
• Location and dates: say when the lighting is required.
• Zones and approximate sizes: a marked photo or sketch is welcome; mention the work in each zone.
• Hours per day: separate this from the rental duration.
• Access and restrictions: mention loading access, available power and any restrictions on engine use.

Use the lighting enquiry form if the model is undecided, or the model’s rental/new-purchase page when it is known. Ask what each proposed package changes for the task.
