He and his team will be happy to answer any technical queries you may have.

LAMP OPTIONS

Virtually every product in the Chelsom range is now available with an LED lamp option. Retrofit LED lamps offer good warm white dimmable light distribution from a lamp which closely resembles the old GLS shape. With extremely long life, low maintenance, low energy consumption and cool running, they are becoming the first choice for many hospitality brands.

Chelsom recommend a leading brand dimmable 10W lamp which is equivalent to 75W of incandescent light. Non-dimmable budget options are available as are higher cost options with increased light output. Clear and frosted candle lamp shapes are also available.

Several products within the range have integral LED chips giving excellent light output through acrylic or glass diffusers.

Compact fluorescent options are also offered for most products and are once again high quality, long lasting and warm white.

Finally, halogen options are available where there is a requirement for pure white light and an extra sparkle.

LIGHT CALCULATIONS

The experienced Chelsom consultants are pleased to visit site and discuss lighting schemes and light calculations with clients. Either lux level readings can be taken on site or calculations can be made at Head Office from architects’ drawings and plans. Advice can be given on the location, quantity and type of light sources required.

DIMMING

Chelsom are experts on the interface between light fittings and the dimming systems to control them. Chelsom like to be involved at the concept stage of lighting schemes so that they may give their advice for compatibility for LED and other lamps when using dimming gear such as DALI, DMX or similar. For dimming individual luminaires, Chelsom can offer the relevant components and gear.

EMERGENCY LIGHTING

Whether emergency lighting is required within individual luminaires or is installed remotely, Chelsom are knowledgeable in all aspects of emergency lighting requirements. Please contact the Technical Team to discuss legal requirements and how those standards might be met with Chelsom lighting.

BESPOKE OPTIONS

The Chelsom capabilities for bespoke manufacturing are shown elsewhere on the website and in the catalogue. However, many bespoke options on the technical front can also be added including wireless remote switching, specific colour temperatures, colour changing LED, high power LED, dynamic white effects, etc. During any bespoke manufacturing, thorough thermal testing will be carried out and Chelsom prefer to make detailed prototypes of complete luminaires or luminaire sections to test for light output, function and heat dissipation. Chelsom work with a wide range of manufacturing processes and materials and will always discuss value engineering to meet budgets.

INTERNATIONAL STANDARDS

Chelsom can wire in house to meet all international standards. Luminaires are constructed and tested to comply with the Electrical Equipment (Safety) Regulations 1994 with reference to BS EN 60598- 1:2015 and with the applicable BS EN 60598 Part 2 standard. Most of the range has UL approval and almost all luminaires can be wired for 110V or 240V.

MODIFICATIONS

Most products offered can be modified to meet client requirements. Typical modifications include special paint or colour finishes, integral switching, double lamp holders, marine use, and many more.
