Here at Penhale Quantock Ltd, we offer an extensive range of lighting enclosures available as an empty housing, but also as an assembled luminaire. Furthermore, our bulkheads are available in a range of finishes and sizes to suit application requirements. For example, our Horizon and Solar enclosures are available with a vacuum metalized rim or bezel, as well as a translucent base to offer a halo effect. Above all, we are proud that the majority of our products are manufactured in the UK with all polycarbonate products injection moulded in-house. Together with our supply chain partners, we work tirelessly to ensure we provide the best quality products.  For any further information on our product range please do not hesitate to get in touch with a member of our sales team.

Here at Penhale Quantock Ltd, we have our products tested by the Lighting Industry Association’s laboratory.  This ensures their compliance with the Building Regulations Part B. In addition, this ensures compliance with the BS EN 60598 luminaire standard which we believe is particularly important. Below is a list of specifications we ensure our products have been tested by the LIA.   Furthermore, certificates are available upon request for your technical files.  We utilize this facility during our R&D and test again after if any changes are made to the enclosure during its lifecycle.

Reports Available:

• TP(a)
• IK10
• IP65
• 850 Glowwire

Our Lumaax is the highest performing diffuser on the market in comparison to the competition. When compared to the market standard opal, the Lumaax offers up to a 92% increase in Light Output Ratio in addition to the superior light diffusion. Together with the elimination of hotspots and glare caused by the LED boards, the diffuser subsequently increases the application range available for our enclosures. In addition to the reduction of dangerous glare, the Lumaax enables our customers to reduce their circuit watts as a result of its superior performance.

Luminaire performance varies between enclosures, which generally means careful consideration needs to be made when specifying an internal solution.  The results to the right, refer to photometry test results performed on a range of our enclosures. These subsequently, deliver a variance depending on the enclosure and/or internal solution.  Our Horizon results, for example, are utilizing a 330mm LED board in this case but can be used with a 220mm.

We have been proudly manufacturing here in Somerset since 1980. Our expert injection moulding division produces all our plastic products from the highest quality polycarbonate, in contrast to many imported goods on the market. In addition, our production team can help beyond moulding and assist with any additional processing or assembly requirements. From electrical through to textiles, we have over 30 years of manufacturing experience of here at PQ servicing a wide range of industries.

Our machines range from 30 -400 tonnes, therefore have the capability to manufacture components weighing between 1g and 1kg. In addition to weight, parts can range in their complexity, and consequently require different approaches to both tooling and general production. Nevertheless, our team can assess your projects and recommend the approach most suited to your circumstances.

Polycarbonates come in a wide range of varieties and specifications, and as a result, the notion that ‘any polycarbonate’ will do within the lighting industry is an ill-judged one. Here at PQ we, therefore, ensure all our poly carbs meet the performance requirements set out in the building regs and BS EN 60598 standard.

Impact Modification

In summary, it does what it says on the tin!  Our poly carbs have been impact-modified to enhance their durability and, as a result,  ensure our products meet the IK10 classification.

Tp(a) Rated

TP(a) is a classification requirement under in the building regulations, which outline any polymers used in luminaires comply to specific flame retardancy capabilities.  Many factors can affect the flame retardancy of a polymer, like the thickness of the part itself for instance.  However, here at PQ, we get our products tested by the LIA to ensure our polymers meet the TP(a) classification.

UV Stabilized

Given the opportunity, UV radiation from the sun will generally cause damage to almost anything, with plastics being no exception.  Polycarbonates, however, are known to be one of the most resilient polymers against UV radiation. Our materials have UV stabilisers to increase their resistance to sun damage in addition to the advantages of using a regular PC.  Other polymers have poor resistance to UV radiation, which is ordinarily one of the reasons many diffusers turn yellow over time.

850 Glowwire

In addition to a polymers flame retardancy to an open flame, materials also have a resistance to a heated element. Of course in lighting, this means there resistance to a loose electrical cable.   The glow wire test simulates this, with a classification given depending on the temperature reached before the polymer ignites.  Plastic components, therefore, must be compliant to 850 degrees at least.  Here at PQ, we ensure all our poly cabs are tested by the LIA to ensure their 850 glow wire compliance.
