Q & A
How good is LED light quality?
Our LED luminaires provide remarkable quality and consistency. Since entering the marketplace, LED lighting systems have evolved rapidly, with accuracy and quality improving exponentially. Consistenc…
Can I optimize luminaire output for high flux?
Yes, it’s possible to achieve high flux and CRI. Traditional RGB offerings have very poor white light output. Both because the CRI and max lumen output is typically in the 0-30 CRI range, but also be…
Is IntelliWhite (iW) the best tunable white light?
IntelliWhite is only one way to achieve tunable white. IntelliWhite (iW) luminaires allow you to change the quantity of different color temperatures, mixing to create a hue of white. For many lightin…
What is the best way to combine color-changing and white LED light?
IntelliHue lets you do both. Galeries Royales Saint-Hubert - Brussels, Belgium, uses IntelliHue technology to achieve white and color light in the same installation. Using a combination of RGB and Es…
Are more LED channels better?
Not necessarily. Adding more channels always comes at a cost. This approach may offer a larger gamut (e.g., royal blue, or photo-red at 660 nm). But the solution will optimize for maximum gamut, and…
Do RGBW luminaires create white light with the white channel only?
No, the RGB channels can also be used, increasing lumen output and delivered light. You can program the luminaire to use the white channel alone and achieve approximately 80 CRI, but the output of th…
How long do LEDs last?
Like all light sources, LED sources fade slowly over time. Well-designed LED luminaires can retain 70% of their initial output for 50,000 hours or more, depending on operating conditions – delivering…
Can RGB luminaires output high-quality white light?
Quality can be poor when using traditional RGB luminaires to create white light. By increasing the number of channels to four or five can increase and improve your light output. Using an RGBW luminai…
Can multi-channel luminaires achieve high color consistency?
Yes, as long as they're designed and manufactured to achieve it. Edinburgh Castle Color Kinetics IntelliHue luminaires that use Chromasync technology achieve <2 SDCM/MacAdam ellipses from fixture to…
Are LED systems costly?
Not when you consider the total system cost, including maintenance and power use. Initial fixture costs may be higher for some LED lighting solutions than comparable incandescent and fluorescent ligh…
Can white-light LED sources produce 200+ lumens per watt?
No, the quest for higher efficacy leads to dubious, unverified claims. Many manufacturers test their LED chips on lab benches at room temperature with short pulses – producing a high level of efficac…
Are 3-watt LEDs 3x brighter than one-watt LEDs?
No, in general, the brightness of an LED source is not cumulative. Incandescent lighting was simple to measure and compare – a 100-watt lamp was brighter than a 60-watt lamp. Evaluating the brightnes…
Do RGBW luminaires make the best white light?
That’s only one way to deliver white light. Many lighting designers assume that to get a good white, they simply need to add a white LED chip. While this is a quick way to create white light, they ar…
Can color-changing luminaires achieve high R9 values?
Yes, but not in all cases. Red rendering can be poor if you choose a traditional RGB luminaire. The R9 values will typically be negative, since red will be very over-saturated compared to other color…
Do LEDs generate heat?
Yes, they do generate some heat, but not as much as incandescent sources. One of the core benefits of LED light sources is that they create a cool beam of light. However, they do produce waste heat w…
