What is it and how does it work?

It’s designed as a replacement for 400-Watt ‘High-Bay’ lights (consuming about 450 Watts with ballast losses) and holds 4 55 Watt PL fluorescent lamps (about 230 Watts including ballast losses) in a highly efficient reflector with the option of daylight and motion sensors to further reduce energy use.

What spaces will it work with?

Designed to work at a height of 5 meters or more Eluma is ideal for large indoor spaces such as warehouses, distribution centers, bulky goods stores and indoor sporting stadiums. Eluma can be enclosed for food areas and operates at much cooler temperatures which saves cooling costs in temperature controlled areas.

What operating conditions suit the Eluma?

Temperatures from -25 to + 50 degrees celcius.
Supply voltage between 198 and 264 AC/DC.
AC current between 50-60 Hz.

What is the quality of light like?

High frequency compact fluorescent lamps operating at 40,000 Hz create a steady, flicker-free light that reduces eyestrain and headaches. The light fitting is larger thereby reducing glare and the light has a colour rendition index of around 84, which is closer to daylight than nearly all-comparable lighting options.

How does the occupancy sensor work?

The auto shut off can be set to 4, 8 or 16 minutes and saves 100% of lighting costs. This function extends lamp life and allows Eluma to double up as an after hours security light. You won’t have to wait for lights to warm up and they switch off automatically when not needed.

How does the Daylight Harvesting work?

The sensor models monitor the amount of ambient daylight and compensate for it by dimming the light output of the lamps in proportion to the amount of daylight.

What about lamps?

Each Eluma takes four 55 Watt, four pin, single ended, 840 PL fluorescent lamps. They are a common lamp and cost around $20 each for Osram Deluxe L, GE Biax or Lumilux lamps or $45 for extra long life Aura Unique-L. Contact us for further details on sourcing lamps.

What is the warranty?

Warrantee is 2 years excluding lamps. If one lamp goes there will still be three burning and the sensor model will drive them harder to compensate, if one of the two ballasts fails the remaining ballast will still provide half the normal light with two lamps.

Can I get photometrics and plug-in's for my lighting design?
