SJS Technology: Khosla Shines On Lighting Startup


We know we’ve given cleantech venture investor Vinod Khosla a lot of ink this week, with our 5-questions interview. But, hey, we just follow where the money flows. According to a regulatory filing picked up by, Khosla Ventures is leading a Series A round of funding for Goleta, Calif.-based solid state lighting startup SJS Technology. The report says SJS Technology has secured $2.5 million of a $5 million round.

This is the first we’ve heard about SJS, but Khosla is no stranger to investing in efficient lighting. So far he’s invested in another solid state lighting startup Group IV Semiconductor, which we wrote about here. As well as Topanga, which the firm describes as selling high intensity discharge lighting, and Lumenz, a zinc-oxide based efficient LED company.

While most of us are already switching out incandescent bulbs for compact fluorescents, options in solid-state lighting technology are the next generation. Solid state lighting commonly uses layers of semiconductors to create light in a much more energy efficient method than traditional lighting, and includes utilizing light emitting diodes (LEDs). In five years cheap, inefficient incandescent bulbs will be illegal as mandated by the recently inked Energy Bill, and this is blazing the way for solid state.

Dr. Light

I never thought I’d see the day that the lights I have used everyday would become illegal. Our world evolves so fast. Thanks for the post, keep up the good work.


Green energy is definitely the best solution in most cases. Technology like solar energy, wind power, fuel cells, zaps electric vehicles, EV hybrids, etc have come so far recently. Green energy even costs way less than oil and gas in many cases.
