Description

Smart-8 Medic Grow Full Spectrum 760W LED Grow Lights for Indoor Plants

Be smart about your choice! Meet the foldable Smart 8 that is designed specifically for high PPFD cultivation practices in growing.

Smart 8 760 watt is built using high quality Sosen drivers and top bin LEDs from Osram generating a full-spectrum light source ideal for veg and flowering cycles. It covers each phase of growth from vegetative to flowering and casts an area up to 5x5 in flower. Producing outstanding PPF of 2136 μmol/s and a photon efficacy of 2.8 μmol/J, it can also deliver the entire spectrum of light evenly to your plants, giving them exactly what they want to grow big and fast.

The onboard easy-to-read LCD display allows you quickly and easily to check your timing settings, power, dimming, spectrum, PPF and more. There are two built-in knobs above the screen. The right one allows you to easily dim the light from 100% down to 80%, 60% and 40% intensity without the need for any external controllers, while the other is to schedule time for your plants at 6/12/14/16/18 hours. The Bloom button sits between the two knobs, giving you the convenience of switching the spectrum from vegetative (V1) to flowering (F1).

For commercial growers, the Smart 8 can be externally daisy chained with a medic grow lighting controller featuring light timing, dimming (1% increments), temperature control for up to 75 fixtures. Each light has a general life expectancy of 50,000 hrs and a 5-year long warranty period, thus, you will get full assurance from us about the durability of the lights.

Test&Review

The detail PAR and ePAR review for Smart 8 is from  Dr. MJ COCO

I ran a total of 9 PAR and ePAR tests with the Medic Grow Smart 8. I tested it in a 5×5 space with and without the Bloom button activated. It is plenty of light for a 5×5 space but with such a good price I know growers with 4×4 tents will want to know if they can squeeze it in. I ran tests in a 4×4 at full power for growers with supplemental carbon dioxide. Most growers will have to dim the Smart 8 in a 4×4. I tested it at both 60% and 80% and it made impressive density maps perfect for growers without supplemental carbon dioxide.

In the 5×5 space, I set the hanging height based on the Maximum PAR PPFD with the Bloom switch on. The Smart 8 had a maximum PPFD of 1000 µmol/m² at a hanging height of 58cm (23in). The Smart 8 puts out a lot of light and the distribution is great. The lowest PPFD in the corner is 508 µmol/m² in the PAR range (400-700nm). The values are slightly higher in the ePAR range (400-750nm). In the ePAR test, the maximum PPFD ticked up to 1027 µmol/m² and the lowest corner came up to 533 µmol/m².

In the PAR range, the average PPFD is 747.9 µmol/m². That converts to a usable PPF of 1682.8 µmol. I measured a power draw of 750 watts, so the Smart 8 produced 2.24 µmol of PAR light per watt. In the ePAR test, the average went up to 775.3 µmol/m², which converts to a Usable ePPF of 1744.4 µmol. The Usable Photon Efficiency in the ePAR range is an impressive 2.33 µmol/w.

 

When I switched the Bloom button off, the power draw went down by about 9%, but the PAR and ePAR values only went down by about 7%. The Smart 8 is slightly more efficient with the Bloom button off. It had a Usable Photon Efficiency of 2.27 µmol/w in the PAR range and 2.37 µmol/w in the ePAR range. Remember, when the bloom button is off, the 660nm diodes are dimmed. The change to the spectral output is minor. You can freely use the bloom button during the whole grow. Turning it off will lower the total flux slightly, and improve the efficiency, which is fine during veg.

In a 4×4 space, the Medic Grow Smart 8 can provide ultra-high density for grows with supplemental carbon dioxide. I ran PAR and ePAR tests with it hung at 12” (30.5cm) above the sensor. The Maximum PPFD in the PAR range was 1481 µmol/m², which is safe for grows with carbon dioxide at 1200 PPM. The fixture is a tight squeeze in a 4×4 space, extending nearly wall to wall. Although the hanging height was low, the distribution of light created by the 8 LED bars is excellent.

 

After the ePAR test at 100% power, I wanted to run a test at 80% for growers without supplemental carbon dioxide. However, at the 12” hanging height, the maximum ePPFD was still close to 1300 µmol/m² at 80% power. I dimmed the Smart 8 to 60% power and the maximum ePPFD was 989 µmol/m², which is close to perfect for growers without supplemental carbon dioxide. The lowest ePPFD is 566 µmol/m², which is also great. With 60% power and a low hanging height, the efficiency was outstanding at 2.56 µmol/w. In a 4×4 space, most growers will have excellent results running the Smart 8 at 60% power 12” from the canopy.

 

 

 

At 80% power, growers without supplemental carbon dioxide will have to raise the Smart 8 considerably. It is possible to keep the maximum PPFD within the 1000 µmol/m² limit, but I had to raise the Smart 8 up to 66cm (26in) to get there. The efficiency is slightly lower in these tests because the hanging height is so high, but the distribution of photon densities is excellent. The lowest PPFD in the PAR range is 833 µmol/m², which is 83% of the maximum.

I am impressed with the performance, build quality, and especially the cost of the Medic Grow Smart 8. The performance stands up with the top fixtures on the market. It provides excellent coverage and superior photon efficiency. It is well made and has useful features for home growers.
