Er, obviously I wasn’t saying a 20w was about the same as a 400W!! That would just be silly. I was saying that PER WATT OF POWER, a compact flo doesn’t produce that much less lumens than a HPS light. So for a kilowatt of power paid to the electricity company, a compact flo doesn’t produce a great deal less lumens than an HPS.
In other words, rather than the one HPS light, hypothetically, I could use 22.5 compacts and still achieve the same amount of lumens. While using more watts, I could obtain the same amount of light by paying LESS MONEY for the 22.5 compacts than I would for an HPS light. Do you understand now? How then, is the HPS better than the 22.5 compacts (apart from the watts)? |
