Not my system, I dont own one - just trying to get awareness out. This is marketed at the low end and its inefficiency makes it a less desirable solution than other low cost setups. The lamp was tested by some guy at 420 magazine, details in my previous post.

I reckon! I dont understnad how the transformers work, but I know they should be a lot more efficient than that. Ive checked out some other 150w ballasts on the net and they have consumption around 180w too. Heres the link to the review on the light...

Not all ballasts are created equal. I still cant get over the 150w HPS Sunsytem that seems popular, that thing draws 408w continously! Over 500 at startup. So check the current draw(AMPS) of your ballast, ignore the lamp. Multiply that by your line voltage, and you get your power consumption.

A guy linked to one of these lights in another thread http://420magazine.com/forums/grow-supply-product-reviews/91592-review-sun-system-150w-hps-system.html The thing consumes 408 watts! Seems like a very inefficient ballast. It is a cheap light, but the running cost is nearly the same as a...

The more I look at it the more I like it. I like the way you can distribute the light with 'pipes'. The Lamp can be in a totally different room to the plants, while allowing you to deliver light in a very targeted and modular fashion, much the same as hanging lights in/amongst/on the sides of...

I hope this diagram helps with understanding how lux and lumens add. Lumens are a measure of photons, weighted to the sensitivity range of the human eye. Photons are the basic unit of light. The more powerfull the light, the more photons are emitted. As a photon is a unit of measurement, a...

hehe no worries mate, cheers nonetheless :bigjoint:Gotta say your colas are a fkn inspiration lol

when you say the plants were smaller during veg, do you mean they seemed to have less nodes/branches/foliage, or just reduced internodal distance?

hehe Oxy, I want to know why MBlaze doesnt like MH lights, but I didnt see one thing in your post about MH lights :eyesmoke:

sorry, not trying to be a dick, but I didnt understand any of that :confused:

Im interested to hear your reasons for this, could you please elaborate? Like many here, I got a lot of respect for your gardening skills :weed:

I believe there is a book, by a member of this site, where he claims .76g/watt. Its not unheard of. Im sure others can give u actual links to it and other grows, or u could always read up b4 calling BS :razz: He must be thinking about ultraviolet light, which can be harmfull. However, HPS emit...

Thats about right for chlorophyll absorbtion peaks, but plants have other pigments that collect light energy more efficiently at different wavelengths, such as chlorophyll-b and carotenoids. CFL can be narrow spectrum like an LED, or broad spectrum like sunlight. It depends on the phosphors used...

Im pretty sure that in most cases 400w of CFL will give off more heat that 400w of HPS. Reason being is that CFLs are generally less efficient at converting electricity to light. The wasted electricity is converted to heat. This HPS lamp will of course run at a higher temperature than any of...

Nice mapping - makes me wonder, is it practical to use similar mapping techniques in order to design a canopy shape(ala stadium scrog) tailored to individual light fixtures/grow areas?
