So i've used this Vipar red/blue/green cob grow light in a past grow (so can say it grows bud). It has nine cobs onboard (all the same). Two switch controls allow the user to have either four cobs, five cobs or nine cobs on at any one time (in differing configurations). All of this i liked when i fist saw the light a few years back. Although i have since moved on to other lights (just experimenting).
However, i noticed this Vipar cob style seemed to 'come and go' (i'm guessing due to improved spectrum/effieciency etc etc with other lighting). I just wondered if anyone here could give me info why Vipar seemed to go back to leds ..and i don't see others using this cob style. Its still quite 'blurple' in colour but the red/blue/green was stated as creating a full spectrum
but as stated the light grew bud. Obviously the new cobs are head and shoulders better but still was surprised that noone else seemed to have used them ..made me a little paranoid
fyi - When measured this units actual draw was approx. 565watts (measured over first 5 minutes of turning on all cobs ..although watts were still dropping slowly - i think this is a cob thing).
So, are these cobs just very inefficient and so got phased out / past over by other companies?
*added pics of the grow i did with this light (light filter added to give natural lighting).Tent is 1 square meter and 2 meters high - eight small (averaged 21 inches high) plants in the tent, mixed coco/soil grow*
Original specs from Vipar
It was quite a lazer! I did lower it too much (i got it down to 14 inches!) as there was some bud/leaf bleaching. If i use it again I'll keep it 24 inches from tops.
*update - i think Vipar became Viparspectra*
