Thanks for the expert advice. I have an hid but it's only 150 watts. I am tempted to buy a 400 watts upgrade but I imagine this wont be anytime soon. Maybe by the time I am ready to buy Sulphur / microwave lamps will be the way to go !
chinGON Reviewed by chinGON on . Solar Powered Lamps Free Light from Dusk till Dawn I was browsing through an Architectural mag and read an Ad for Solar-Powered Lights manufactured by Solatube Solatube Daylighting System and Tubular Daylighting Devices for residential or commercial daylighting and sunlighting needs are the smart alternative to traditional skylights and I am wondering if these work. If they do perform as far as lumens and spectrum then their relative high price may be well worth it (about $350 dollars.) If you haven't used these but want to review their data Rating: 5
