Abstract: Antimicrobial compositions including at least one acid and at least one anionic surfactant are provided. In particular, food contact antimicrobial compositions including at least one acid and at least one anionic surfactant provide efficacious virucidal activity, including against Norovirus, having acceptable use solution pH that do not require use of personal protective equipment (PPE), are surface compatible and do not leave residues on treated surfaces. Methods of cleaning a surface with the compositions are also provided and may beneficially eliminate the need to rinse the antimicrobial compositions after use.

Abstract: A method for control of a light fixture, the method including energizing the light fixture to produce a first light output with a first chromaticity and a first spectral power distribution, receiving a user input representative of a desired adjustment of a lighting effect, generating a target spectrum based on the user input, and energizing the light fixture to produce a second light output with the first chromaticity and a second spectral power distribution. The second power distribution approximates the target spectrum.

Abstract: Systems, methods, and devices described herein provide for operating a lighting fixture with a plurality of light sources at a target chromaticity with a target output spectral power distribution. The methods include multiplying a first spectral power distribution by a second spectral power distribution to determine a product spectral power distribution, multiplying the product spectral power distribution by an illuminant spectral power distribution to determine the target output spectral power distribution at the target chromaticity, and driving the plurality of light sources at intensities corresponding to the target output spectral power distribution.

Abstract: An LED light fixture comprising a plurality of LEDs mounted on a substrate, wherein the plurality of LEDs include a lime/mint light source accounting for at least 25% of the total lumen output, and a deep red light source accounting for at least 0.5% of total lumen output. The lime/mint light source preferably accounts for at least 50% of the total lumen output. The deep red light source preferably accounts for at least 1.0% of the total lumen output. The light fixture can also include other colors, such as 1% to 50% cyan, 1% to 20% red/red-orange, and 1% to 10% blue/indigo. In one embodiment, the fixture further includes a processor for calculating a color mix and driving the LEDs. Preferably, the processor is programmed to produce a color mix having a CCT in the range of 2700-6500K, a TM-30 (Rf) of at least 90, and a TLCI of at least 95.
