===Solarium with Grow light LEDs=== There is going to be enough light reflecting off the floor and other objects to light the whole room. Strongly considering cool white and deep red flood lights. **300 watt LED is a street light** The plan is to build 2 or 4 of these lights. Shine these out the window and they will light the court yard like it is day. **Notes** All prices are estimates. Bidding and other sources are recommended for actual purchase * Lighting must be compact and easy to install onto a concrete ceiling. * light weight LED rgbw strip mounted on an aluminum LED strip and acrylic sheet holder. * drill the aluminum strip after to match the concrete drilled ceiling holes and attache the aluminum strip to the crown modeling when possible * hide the the power supplies inside the crown modeling * must be remote / electronic controlled * moisture test would be very nice too.

I like that a lot * $217 5M for 43w meter = $217 for 215w Some thoughts * Can we use 2 thin acrylic sheets conned together for the dual row led strips rather than one very thick acrylic sheet? * Individually LED strips addressable is quite expensive. They will look cool but I don't think they are worth the expense for a grow light system. * Cut 12V rgbw into shorter lengths and wire them every other 1 together or every other 2 together * We don't want too many 12V drivers. * Do we build our own 12V drivers or we buy them. * 12V pwm drivers or simple 12V supplies.
