An introduction to the Spectrum King - the biggest indoor lighting innovation of the decade. Coming straight from the USA, the Spectrum King represents a huge leap forward for LED technology, producing rich, full spectrum light at an intensity that rivals high pressure sodium (HPS)! It does this while running at low temperatures and consuming less than half the power of its HPS equivalent. Wow!
