Ceramic lighting tech has actually been available for some time. They were first marketed for use in retail and commercial fixtures as an alternative to unnatural looking yellow-orange HPS bulbs or traditional Metal Halides which dim and burn out more quickly. Similar to a standard HPS bulb except the filament runs at a higher temperature giving them a high Color Rendering Index (CRI), truer to natural sunlight. The upshot was a lamp with the long life of a HPS. As well as a spectrum that couldn’t be matched by the best metal halides, and also capable of putting out excellent PAR measurements.
Naturally, when growers first stumbled on the specs for these retail bulbs It seemed a little too good to be true. Once people actually started using them and showing off the difference it made in their plants, ceramic lamps gained a following and the industry began to notice. We can talk PAR, spectrum and PPFD all day. And yes LEC lamps do excel in those areas, but perhaps more compelling is the fact that this tech was discovered “in the field” by growers just like you. It has been researched and vetted not in labs but in garages, basements and warehouses. This is a product that pushed its way into the market and onto grow room shelves as a response to consumer demand.
