| Test Methods |
| Spectral Measurements – Integrating Sphere A Sensing Spectroradiometer SPR-3000, in conjunction with Light Laboratory 2 meter integrating sphere was used to measure chromaticity coordinates, correlated color temperature(CCT) and the color rendering index(CRI) for each sample. |
| Ambient temperature is set to 25oC and is measured from the center of the fixture, within 1ft from the outside of the fixture. Temperature is maintained at 25oC throughout the testing process and the sample is stabilized for at least 30mins and longer as necessary for the sample to achieve stabilization. |
| Electrical measurements are measured using the listed equipment. |

This is great performance. Has ChilLed described how this high efficacy is achieved? It seems higher than the component samsung 301h could provide at 3.1 umol/j Are these lights using different diodes?
Ahhh it’s only 39” wide. This leaves room to have it so you can pull it apart to slide it out to 44-46” this will allow you to separate the two center if there is a hotspot. Just my two cents but thought I’d toss the idea out there.
Exactly! Two halves and the freedom to place them at your desired distance apart.
Damn. You guys did it again with another sweet light. Good job to everyone on the team.
I didn’t see the overall spectrum in the specs. Is it around 3000k?
Thank you, ROG. We appreciate you taking the time to comment and leave your feedback. The CCT is around 3700K – 3900K range. The CCT, CRI and others are listed in the left column next to the chromaticity diagram.
Sweet deal. I’m not to sure about the two center being so close together. This was probably done as there is a 300 series? If there is a hotspot as I suspect, maybe something can be done so you can slide them apart to make them an even distance? The user can move them apart themselves on some sort of slider would be a good idea since it’s still a prototype.
Or is there a hotspot at all?
Very nice light but I’m a little concerned about the two center bars being so close together.
Nice catch! It’s just for the test report photo. The prototype consists of two X3 fixtures powered by the Meanwell HLG-600H-48B LED driver, one driver output for each half of the full fixture. The PAR map will look the same as our regular X6, just with higher output 🙂
Ahhh ok, I gotchya. Yep two 3 bars work. Thanks for the fast reply. You can delete my comment afterwards as I didn’t think you would answer so quickly.
Thanks
