Just want some input into what you would choose?. With experience using the light, I lean toward cmh in the below setting but do chime in to talk me out of it.
Flower room of 8 plants two lanes wide under scrog, 2x 600hps covers the 3x6 area nicely. The area will expand to 3x10 along with a light upgrade to accommodate. Using another 600 is just too much W and heat with poor spread.
As for what to upgrade to
4x 315's (1 light per two plants) using red/blue/red/blue alternating spectrum's. Cheap wing hoods will be used as I like the spread flexibility when dropping the lights lower (to around 16-18inch) while not focusing the foot print too narrowly, I hope this will play well using alternating bulb spectrum's. As far as I've read the mixture will offer a very nice spectrum evenly spread out across the canopy, for hid at least, on top of providing uv. The cost will fall in at around £1000.
I Have no interest what so ever in DIY cob and was recommended a pre built cob setup from a rui poster.

It looks like 3 of the hc6's would be required to spread over the 3x10 area with an effective light distribution. I don't know much about the spectrum offered but at face value £2400 is not an option. If two of these lights could cover the area that's still £1600, is it worth it?, especially when I read of people needing to supplement uv or what ever else.
The other factor that is on my mind is the heat difference.
With a fan speed controller and 8inch in/out the 4x cmh will keep heating costs down to a minimum in colder weather most dominant in my country while not kicking back to idle speed. In summer heat waves the lights will be on alternating 3 or 6 hour intervals (paired or single lighting) to reduce heat. By what I've read this is still enough light to keep them going nicely and will remove the need for ac bills during those few weeks or couple month of the year.
What I wonder about the cobs is if they will run too cool on the ambient and canopy temp. This means the fan controller will be idle too much to maintain upper temp and then co2 will be reduced as a result. In the brief summer spikes all 3 may be able to run but I don't think this upside is worth the cold months downside, should it be one.
Any thoughts welcome.
