Linear light sources are in widespread use for illuminating commercial and industrial applications worldwide. Office lighting and other commercial applications have been challenging for white LEDs previously because of the need to diffuse the point sources, reducing system efficacy.
The ChromaLit Linear product delivers naturally uniform, high quality light with conversion efficacy of up to 215 lumens per radiant watt or up to 163 lumens per system watt when used with the most efficient blue LEDs available.
“ChromaLit Linear transforms industry thinking about LED linear lighting and remote phosphor,” said Julian Carey, Senior Director of Strategic Marketing at Intematix. “We can forget about low efficacy and pixelation because this product enables high light output, smooth uniformity, white off-state and new possibilities for applications from under-cabinet to troffers to high bay lighting.”
The ChromaLit Linear remote phosphor solution offers flexibility of length. Surface lumen density scales from 500 to 2500 lumens per linear foot and the system presents new design directions not possible with fluorescent and white LEDs.
Intematix says it has also changed how designers think about remote phosphor because ChromaLit Linear has dramatically improved the off-state appearance and illumination quality. ChromaLit Linear offers 3 SDCM colour consistency as standard and colour temperature options from 3000K to 5000K and CRI of 80.
Samples of ChromaLit Linear are available now from Intematix and production quantities are available with standard lead times.
Cree LEDway street luminaires halve energy use
Based on its III-nitride LEDs, Cree is broadening its LED street lighting portfolio with new high output options
Cree is building on its versatile LED street light portfolio with the LEDway High Output (HO) LED street light.
With its higher lumen output, the new LEDway HO LED street light enables the LEDway Series to address large multi-lane freeways and expressway applications, easily replacing inefficient High Pressure Sodium (HPS) lighting up to 400W from a single platform.

The Cree LEDway HO LED street light provides highly focused, directional light at nine adjustable lumen output levels, reducing energy consumption by more than 50 percent compared to outdated HPS street lights in most roadway applications.

“As we’ve already seen with thousands of LEDway Series installations throughout North America and Europe, the Cree LEDway HO LED street light represents another example of why municipalities, Departments of Transportation and Investor Owned Utilities should move to proven Cree LED lighting over incumbent, inefficient technologies now,” says Greg Merritt, Cree vice president, marketing, lighting.
“With virtually no maintenance and using significantly less energy than a 400W HPS, the LEDway HO LED street light dramatically lowers customers’ total cost of ownership. And when you include our 10-year limited
