An online concierge system fulfills orders for items offered by retailers and may increase the price of an item offered by a retailer in some instances. The online concierge system applies a markup to an item by applying a pricing policy to a category including the item. To optimize application of pricing policies to categories, the online concierge system categorizes items offered by the retailer and applies an outcome model to combinations of categories and pricing policies. From the output of the outcome model, the online concierge system selects a set of categories and corresponding pricing policies. Using a price adjustment model, the online concierge system determines modifications to one or more of the pricing policies of the set to enforce one or more constraints across multiple pricing policies.

An optical cup which mixes multiple channels of light to form a blended output, the device having discreet zones or channels including a plurality of reflective cavities each having a remote phosphor light converting appliance covering a cluster of LEDs providing a channel of light which is reflected upward. The predetermined blends of phosphors provide a predetermined range of illumination wavelengths in the output.

Illuminating with a multizone mixing cup

An optical cup which mixes multiple channels of light to form a blended output, the device having discreet zones or channels including a plurality of reflective cavities each having a remote light converting appliance covering a cluster of LEDs providing a channel of light which is reflected upward. The predetermined blends of luminescence materials provide a predetermined range of illumination wavelengths in the output. The remote light converting appliances may be provided as frustoconical elements directly adjacent to the LEDs within frustoconical reflective cavities. An index matching compound can be disposed between the light converting appliances and the associated LEDs.
