Points of light....like the points where the light are coming from? Pierces the canopy? And it's not just all about lumens. Flourescents give a higher quality light with the benefits of choosing a wider spectrum so plants can still get the light they need in smaller amounts for important function, not just limit it to the hps's spectrum which has WAY excess amounts of green to orange between 560-640, which is used very little by either Chorophyll a OR b, which is then converted into HEAT... AND without Hortilux and Sunpulse systems, your digital and/or electronic ballast isn't compatible with HID lights, which causes a bowing and bending of the arc in the HPS bulbs, so not only are you using a limited spectrum hot bulb, but you're losing lumens and stress the bulb, shortening it's life, possibly causing your bulb to explode...
I understand that hundreds of growers produce large dense buds with their HPSs, and that' fine, but it doesn't change the fact it's an entire system (not necessarily yours) that is producing a lot of lumens that aren't being used, and putting out a poorer quality of light. Combined with CFLs etc. would produce awesome things, but I'm not using one light that's going to cause a rise in heat and money, while although possibly giving me a higher yield, will not necessarily give me higher quality, being as how I might going to have to spend a bunch of money to supplement oxygen, Co2, and nutrients if I still want awesome quality, because if I don't, that light is one big ass LIMITING FACTOR.
