Hey, I did the same thing you did :thumbsup: and ordered these lamps.

Some companies have induction lights especially for flowering, that have for example been tested here (in Dutch, but the pictures are very clear).
But any company can produce them if you order enough. They just play with phosphor-mixtures till they find the right one.

You should be able to get 300 watt complete for less than $ 150,= FOB Shanghai.
