HPS vs. Induction + CFL flowering comparison

[vanduction]

Power vs. Grams:

I will ignore the incidental power used to heat or cool the cabinets. Although we all know typically less heat is better because it saves on cooling costs, it's outside the scope of today's experiment.

• HPS: ratio: 0.52g/w (Power used: 315w. Weight produced: 164g.)
• Ind: Ratio: 0.57g/w (Power used: 138w. Weight produced: 78g.)

Conclusions:

I feel it's safe to conclude that, under the conditions of this experiment:

1. This induction lamp did NOT produce the same yield as an HPS lamp when using only 50% of power
2. This HPS lamp is only 93% as power efficient as this Induction/CFL combination

Notes for future experiments:

• A vendor has claimed enclosing the induction lamp's shade would increase its performance
• Insulation & white poly sheathing will be added to the cabinets to improve temperature stability & light focus
• Lamps will be lowered 8"-12" to get closer to the expected final height

Would you also post up the dry numbers when available? So what did you conclude?

If I still have it after it's dried, I will. It would also be nice to give it to a reefer fiend to smoke & give a subjective opinion on the quality, but I can't promise anything.

According to JC, you can estimate dried weight at about 25% of wet weight. Thanks for posting all this! I appreciate your time and effort. :thumbsup: :jointsmile:

HPS: 48g dry
Ind: 28g dry

Bubbas offered me one of his units to test a few weeks ago... now that the next batch is starting up I hope he follows through soon!

I'm very interested to see how a fully designed unit compares to an HPS.

Hi there Vanduction,

I would like to know more about the induction lamp you used for your experiment. I am asking this because i am currently working with one of the chinese manufacturers of induction lighting called Shanghai Genesis lighting and i would love to see the results comparing HPS vs induction or CFL. The fact is that i cant view any of the pics due to the internet ban i have here in China so if you could send me your results i would really appreciate them.

Also if you are still interested in testing more the induction lighting technology get back to me at [email protected] and i will propose you something interesting that will benefit both of us.
