Blau also has an upgraded model to the Lumina. The Lumina Plus adds metal halides to the mix ranging from 70watts all the way up to 250 watts. The smallest plus model will come with 24 watt T5’s, while the largest will come with 80watt T5’s. Similar to the Lumina model, these are made from corrosion resistant anodized aluminum and that switch we spoke of earlier that should control light levels. Just how this accomplished remains to be seen. For a 70watt 4×23 watt T5 unit pricing starts and at respectable Â£309.99 ($499).
