Parking Lot Pole & Optic Sizer
What does the Parking Lot Pole & Optic Sizer calculate?
It recommends pole height and spacing, estimates head count, selects edge/centre optics (Type III/IV/V), suggests an LED wattage band by legacy HID, and projects annual kWh and $ savings with optional quiet-hours dimming.
Which inputs do I need to get a reliable result?
Lot length and width, existing pole height (if any), legacy head type (250 W or 400 W MH), estimated head count, average hours per night, quiet-hours window, and your electricity rate.
How does it pick pole spacing?
It starts from ~2.5–3× mounting height, then tightens spacing along residential edges. Final spacing and aiming should be confirmed with a photometric layout.
Does it account for HID ballast losses?
Yes. It uses typical Ontario legacy system watts: 250 W MH ≈ 295 W and 400 W MH ≈ 457 W, so savings reflect real input power rather than lamp rating only.
How are optics chosen for edges and centre bays?
Edges default to forward-throw Type III/IV to keep light off façades and neighbours; centre bays use symmetric Type V for uniform coverage.
Can it handle mixed 250 W and 400 W lots?
Yes. Choose “mixed” to apply a mid-band LED recommendation and blended legacy watts, then refine during the site layout.
Does it replace a full photometric design?
No. It’s a planning tool for quick scoping. We always validate optics, aiming, light levels, and uniformity with a site-specific photometric before ordering.
What colour temperature should I pick?
Use 3000 K near homes for neighbour comfort and 4000 K in large commercial/industrial yards for crisper visibility. The tool records your choice for the summary.
How does quiet-hours dimming affect savings?
You set a dim-to level (e.g., 30%) and a time window. The tool applies that reduction to part of the nightly hours and shows the added kWh/$ savings versus no dimming.
Can I reuse existing poles?
Often yes—if bases, anchor bolts, and wiring are sound. The tool estimates spacing and head count; we verify pole condition and wind load before finalizing.
Does it store my results?
No. Use the built-in copy and CSV export to save your plan. We can also email you a PDF when you book an on-site assessment.
Who is this for in Ontario?
Facility managers, plaza owners, industrial yards, and contractors who need a fast, Ontario-specific LED parking lot plan before a full photometric and quote.
