Thats a 1000watt HPS bulb kicking out 180,000 lumens? That is more effecient then any bulb I have ever heard of. The most effecient is the low pressure sodium at 200 lumens per watt. Flouros are around 180 lumens per watt but high watt flouro such as the 600 watt bulbs produce RF waves. ( I used them when I made fiber optic cable). You using three 600 watters? A 430 son agro I thought was the most effiecent at 53,000 lumens which is 123 lumens per watt.

karmaxul Reviewed by karmaxul on . Experimenting with extremes. I just set something up I'm going to try out this time. The extreme EC values is because I want to get the most out of the plant possible.I'm gonna build the EC too 2.6 untill the point of overfeeding, when I see the first signs of Nitroger burn I'm gonna drop the EC 20% and try too keep it on there. As we say in the Netherlands, let's see where this ship strands. Rating: 5
