It seems to me we have a pretty free flow of knowledge here. Some say HPS some say MH each have their reasons. Have any of you more experienced cannaphiles done a side by side comparison of the best HPS and MH bulbs? Or, are you just stating an educated opinion?

The best MH's show plenty of red output on analysis. Am I wrong? As far as I can tell the best MH has better red output than any HPS. Although you can't tell by looking at it because there is so much more blue as well. In my opinion MH bulbs right now are showing better light output then HPS. If I am flat out wrong I welcome correction but I think I am going in the right direction here with my observation.

There is also the possibility that the bulb companies are full of shit. That is why I would really like to see if someone has done a comparision.

Is this what you want?

Standard H.P.S. Bulbs

High Pressure Sodium bulbs are red/orange in the spectrum. They are the best lamps available for indoor growing of flowering plants. This type of light promotes flowering/budding in plants. It is ideal for indoor greenhouses and commercial growing applications.


1000w HPS Bulb (140,000 Lumens)
600w HPS Bulb (92,000 Lumens)
430w HPS Bulb (53,000 Lumens)
400w HPS Bulb (50,000 Lumens)
250w HPS Bulb (28,500 Lumens)
150w HPS Bulb (16,000 Lumens)
100w HPS Bulb (9,500 Lumens)


Enhanced Spectrum H.P.S. Bulbs

Enhanced Spectrum High Pressure Sodium bulbs are color shifted to product more blue than a standard HPS bulb. This makes them great for "one bulb grows all" lighting. They have great red spectrum making them a good flowering bulb, and additional blue spectrum making them an effective vegetative growth bulb, keeping the stems from elongating which can happen with standard HPS bulbs during vegetative growth.


1000w HPS Hortilux Bulb (145,000 Lumens)
600w HPS Hortilux Bulb (85,000 Lumens)
600w HPS GroLux Bulb (90,000 Lumens)
600w HPS Plantastar Bulb (87,000 Lumens)
430w HPS Hortilux Bulb (58,000 Lumens)
400w HPS Hortilux Bulb (55,000 Lumens)
400w HPS GroLux Bulb (58,000 Lumens)
400w HPS Plantastar Bulb (55,000 Lumens)
270w HPS Super Agro Bulb (29,500 Lumens)
160w HPS Super Agro Bulb (17,500 Lumens)

So if you can only have one then it's HPS plus if you want a conversion bulb so you can run a MH. HPS to MH conversions are cheaper to buy then MH to HPS bulbs.
