We occasionally have prototype sales. Perfectly good, functional lights at unbeatable prices. They might be cosmetically a bit rough around the edges, and we probably won't be making more of them.
This grow light consists of:
288 x Samsung LM301B diodes (3500K)
288 x Samsung LM561C diodes (3000K)
On a 94% efficient 200W Delta LNE-48V185WAA driver.
Should be a nice full-cycle light for about an 80x80cm tent.
Pretty unlikely there's a better deal for these specs, available in RSA. (Is there?)
Reasons why it's a prototype:
These use previous versions of our grow bars.
We also tried out a thermal glue on some of these panels, so at least one of the panels doesn't use screws, just the thermal glue.
