An incredibly simple and affordable way to incorporate daylight controls into your lighting designs.
The simplicity of Response Daylight extends all the way through to planning and specifying fixtures. To include Response Daylight in your design, simply do the following:
Response Daylight is elegantly integrated in virtually every standard suspended and recessed Ledalite product. To identify which luminaires can be ordered with daylight sensors, look for the Response-Ready icon on specification sheets and product web pages.
Once you have selected a product, all you have to do is add two letters to the end of the fixture's catalog number on your specification documentation.
Designing spaces with Response Daylight isn't complicated, but you will achieve the best results if you do some planning upfront. Ledalite has created a number of tools to facilitate the planning process. You can obtain these tools from the downloads section.
This layout uses the Response Daylight CAD luminaire library to show how two 32ft runs can be configured in a space with two windows.
Alternatively, if you are unable to supply CAD-generated lighting layouts, you can provide a simple sketch to show how you want to configure runs with Response Daylight.
NOTE: If you need additional design assistance, contact your Ledalite sales representative or Ledalite's applications department.
Electronic dimming ballast using 0-10VDC control signal. Controls up to 20 dimming ballasts.
+1.5V to +10.5V control input to ballast. Control voltage variation is less than 0.5V.
Sensor compensates for approximately 50% of additional daylight by dimming the luminaire until the minimum light output at 1.5V is reached. Light output at 1.5V may vary depending on ballast used.
Factory calibrated to a set-point of 45 footcandles (fc), adjustable by 1/3 to 3 times the default setting by rotating the aperture.
Assuming standard room reflectances (80/50/20), a light level of 45fc on a work surface 2'6" high will result in approximately 2.5fc seen by the photosensor at 8'.
Ambient temperature 41-131°F (5-55°C). Relative humidity 15-90%.
Sensor is field-replaceable.
Certified to UL and CSA standards. Title 24 listed.
