HB ProStrong Ø300 150W PIR High Bay Cool White - Grey

The HB ProStrong is a round high bay ceiling light running on 220 to 240V AC, switchable across 150W, 112.5W and 75W to deliver 25500, 19125 or 12750 lumens as required. It throws 4000K cool white light through a wide 90 degree beam, with a built-in PIR keeping output reactive to movement below. American buyers shopping for a flush mount LED ceiling light or commercial high bay will recognise the same format here, scaled for larger floor-to-fixture distances. At its full setting it puts out a strong, even wash that keeps tall spaces bright without hotspots.

Measuring Ø299 by 112 mm, it suits warehouses, workshops, loading bays, plant rooms and covered yards where ceiling heights are generous and the fitting needs to reach down. At general lighting levels the selectable output covers around 42 to 85 m² depending on the wattage chosen, so a single unit can light a modest bay or a run can be spaced across a larger floor. The integrated PIR makes it well suited to intermittent-use areas such as storage aisles and stairwells, bringing the light up on approach and dropping it back to save energy when the space is empty.

The body is aluminium alloy in a grey finish, rated IP65 against dust and water jets and IK08 for impact, which makes it dependable in exposed outdoor and wet locations as well as harsh indoor sites. It carries an integrated LED rated to 50,000 hours, is dimmable via a 1-10V signal and mounts either suspended from the ceiling or fixed directly to it. Ra 80 colour rendering keeps surfaces and signage clearly legible. This high bay sits within our wider HB ProStrong range, with matching fixtures available for larger commercial and industrial installations.

How large an area does it light?

At general lighting levels it covers roughly 42 to 85 m² depending on which power setting you select, from 75W up to the full 150W. A single unit suits a modest bay, while spacing several across a floor handles larger warehouse and workshop spaces. Ceiling height and the spread you need will guide how many to fit.

Can it be used outdoors?

Yes. With an IP65 rating it is sealed against dust and water jets, so it is suitable for exposed outdoor and wet locations as well as covered yards and damp industrial sites. The aluminium alloy body and IK08 impact rating add durability where knocks are likely.

How does the PIR sensor work?

The built-in PIR detects movement below and brings the light up automatically, then drops it back once the area is clear to save energy. This makes it a good fit for intermittent-use spaces such as storage aisles, stairwells and loading bays. It pairs well with the 1-10V dimming for setting standby and active brightness.

How should it be cleaned and maintained?

Wipe the lens and grey housing with a soft, dry or slightly damp cloth once the fitting is switched off and cool, avoiding solvents that could mark the finish. The integrated LED is rated to 50,000 hours, so there are no bulbs to replace over its working life. Keeping the lens clear of dust helps maintain full light output.
