Glad I'm not the only one lol.I have noticed that after a few minutes of it being turned on it brightens itself to a clear mix of the two colours so it's just the initial first couple of minutes where there was really a visible divide between the two, which should mean it wouldn't really matter which direction it's pointing.
Thanks for getting involved folks.
Time to see if my plants like the new light
Oh yeah, before I go, any ideas how many plants will sit comfortably under a 125w?
I have 4 but they don't all need to go under this light. I want them to be comfortable as I say, no fighting for light if I can help it.
you want 3-5000lumens per square foot or some go by a simpler 50watt as a minimum per plant i think.
i wouldnt put more than two in if i were you. what size is the grow area though? smaller the better to keep up lumen/light intensity.

Well, I've made it so it's extendable in both height and width but right now I have it at 3.5'x2'x2', as you say, trying to keep it as small as possible but this can be doubled in all directions.
I have 3x 10L tubs in there atm, all with plants in but I can easily remove one and leave just two under the new light.
I also have 5x 30w CFL's to dot about at a later date just to help things along.
I also have a whole host of other seedlings but I'm trying to concentrate on these three's home for now as they're the eldest, when I said four before I meant to say I wasn't willing to have more than 4 in this room I'm in now. The rest are going elsewhere

I use a 250w red cfl and get four ounces from four plants, each in a 2L pot using organic soil and nutes.
That's crazy about the dual spec, i always assumed they would 'mix the light' internally somehow, not have literally half the tubes red and half blue !
I would have exactly the same worry as you, one side of the grow area will be getting loads of veg and the other half loads of flowering light.
Sure the reflector will mix up the light shining upward from the bulb but not the downward light beams.
I wonder how they do dual-spec in an HPS then coz it's only one bulb isn't it ?
All the best,

my rule of thumb with cfl's is 150w for first plant then 50w extra per plant 
i read it somewhere ages ago but seeing as im using a 300w (actual wattage) for 2 plants currently so dont really need to worry about plants not getting enough light
