HB ProStrong Ø300 150W LED High Bay IP65 Cool White - Grey

The HB ProStrong is a round LED high bay that fixes flush to the ceiling or hangs on a suspension, throwing a wide 90 degree spread of light from a single integrated source. It draws 150W and pushes out 25500 lumens at an efficiency of 170 lm/W, giving a bright, even wash across the floor below. The colour temperature is fixed at 4000K, a clean cool white that keeps work surfaces and walkways clearly lit. American buyers shopping for a UFO-style flush mount LED ceiling light will recognise this format, where the whole disc sits tight to the structure rather than dropping on a stem.

The high output suits tall spaces such as warehouses, workshops, sports halls and covered loading bays, and the IP65 weatherproof rating means it also copes with car parks, canopies and exposed outdoor positions where rain and dust reach the fitting. At general lighting levels the 25500 lumens cover around 85 m², so a handful of units laid out on a grid will light a sizeable industrial floor. Ceiling height matters more than room shape here: the wide 90 degree beam works best mounted high, where the light has room to open out before it reaches working level, and spacing should be planned to keep gaps between bright zones to a minimum.

Built around an aluminium alloy body in a grey finish, the ProStrong carries an IK08 impact rating alongside its IP65 sealing, so it stands up to knocks as well as weather. It runs direct from 220 to 240V AC mains and is DALI dimmable, letting it tie into a managed lighting system for scheduled or zoned control. Mounting is either ceiling-fixed or suspended, and at 2.31 kg per unit the supporting point should be chosen accordingly. The rated lifespan is 50,000 hours. This range also includes other power and size options for larger or lower bays.

How large an area does it light?

With 25500 lumens it covers around 85 m² at general lighting levels, making it suited to warehouses, workshops and large covered areas. The 90 degree beam opens out widely, so mounting it high and spacing units on a grid gives the most even result across an industrial floor.

Can it be dimmed?

Yes, it is DALI dimmable, so it can be controlled through a DALI lighting management system. This allows scheduled, zoned or daylight-linked dimming rather than a simple on and off switch, which is useful across larger commercial sites.

Is it suitable for outdoor or wet locations?

Yes. The IP65 rating makes it weatherproof and suitable for exposed outdoor and wet locations such as canopies, car parks and loading bays. It resists both dust ingress and water jets, so it does not need to be kept under cover.

Does it use a replaceable bulb?

No, it has an integrated LED rather than a changeable lamp, with a rated lifespan of 50,000 hours. There is nothing to replace during normal use; when the LED eventually reaches the end of its life the whole fitting is changed.
