Operating costs $0.05/hr on left $0.11/hr on right.
Not including additional energy requirements of fan/ventilation on right due to higher heat output of HPS lamps.
Grow on the left side stays much cooler. Higher risk of hot spots on right (HPS provides uneven light spread and poor light mixing/spectrums) and lower risk of hot spots on left (COB chips provide an even spread with best light mixing and optimized spectrums).
PS: Left side may last 10 years with no replacements needed and right side will require a new bulb every 5-7 months ($40-$70 depending on where you get it from).
The Scorpion COB LED grow lights on the left are producing full flowers
Flowers on the 1000W HPS are looking a bit behind compared to the ones growing under a 550W COB LED grow light (Growthstar Scorpion).

Again, not surprisingly, the flowers under the 1000W HPS (shown below) are less developed than the ones growing under the 550W Scorpion chip on board LED grow light.Which side looks healthier? Left or right?
Two plants grown under a 550W chip on board LED grow light (Growthstar Scorpion) vs some generic 1000W HPS grow light.
When we saw these pictures we thought to ourselves, man... If companies selling anything other than chip on board LED grow lights saw this they would freak out. Of course they don't want the public to know... They would be out of business! That is scary for many considering how quickly things are changing in the cannabis industry.
"We estimate that the U.S. cannabis consumer market for legalized recreational and medicinal use was $4.4 billion in 2015
and will grow to $9.5 billion in 2019. Once legalized federally,
we estimate this market will grow to $37 billion within 5 years
and $50 billion within 10 years." - New Cannabis Ventures
