Frequently asked questions
What is the Alphard bulkhead and where does it work best?
Alphard is a surface mounted architectural halo bulkhead designed for optimal light diffusion, suited to decorative interior and exterior applications such as lobbies, corridors and communal circulation areas. It has already been installed in projects including Lynch Hill Academy in Slough and Altitude Business Park in Cheshire. Its cast aluminium body and halo diffusion give it a more architectural appearance than a standard bulkhead.
How robust is Alphard for busy or exposed locations?
Alphard combines an IP65 rating against moisture with an IK10 rating for impact resistance, backed by a cast aluminium body and a TP(a) rated opal polycarbonate diffuser. This level of protection suits stairwells, corridors and exterior circulation areas where knocks are more likely. The TP(a) fire rating on the diffuser adds a further layer of reassurance for specifiers on compliance-sensitive projects.
What finish and shape options does Alphard come in?
Alphard is available in a round or square profile, so specifiers can choose the shape that best fits the ceiling or wall layout of a space. Black is the standard finish, with white available as a special order option. This gives some flexibility to match Alphard to the existing decor of a building.
What control and emergency options can Alphard be specified with?
Alphard supports DALI 2 dimming as well as mains, 0-10V and DSI dimming, so it can be integrated into most standard lighting control systems. It can also be specified with an integral microwave sensor, integral emergency operation, or a Z10 remote control integral emergency version that allows testing without physically accessing the fitting. Combining these functions into one bulkhead reduces the number of separate fittings needed in a corridor or stairwell.
What should contractors consider when installing Alphard?
Alphard is designed for ceiling or wall mounting and has back cable entry, which keeps the cabling concealed for a cleaner finish. At 2.50kg, it is light enough for straightforward first fix, and its integral driver removes the need for a separate remote gear tray. These details help keep installation consistent across multiple positions on a project.
