Liteline is a Canadian company that offers a good option for downlights with a low price point. They have a warehouse stocked and can ship the next day. The Sigma 2 is a 2" aperture downlight. It is offered in 3K and 4K with 15°, 30° or 60° beam spreads. They have multiple overlap trim options and are working on a mud in trim. The fixture has 500 delivered lumens.
Slim LED is another downlight family that we saw and is offered in either round or square. The fixtures have only a 1/2" thickness to them and are available in 4" and 6" apertures. They are ETL listed with the driver in plenum ceilings.
We also got to see a prototype for a track head that includes warm dim technology. The fixture head is small and has a lower output than we would typically use. But we liked the idea and will be interested to see how it develops further.
