Making Room For Do-Gooders
Elvis Summers found himself looking
for a more profound way to help a
60-year-old homeless woman who
collected recycling in his
neighbourhood.  He came up with
the idea to build "Smokie" a tiny
house on wheels.  The local police
were on board as long as the
mini-shelter was moved to a different
spot every 72 hours. Inspired by the
grateful face of Smokie when she
received the keys to her new home,
Elvis took it a step further; starting a
GoFundMe campaign to provide more
homeless people with mini shelters.  
So far he has raised about $13,000
which translates to providing a relief
to about 26 struggling humans.

LGM LED Grow Light
Same Area- 12 Different LED Grow Lights
With so many options to choose from, how do you know which option is right for you?  The "Best LED Grow Light" isn't
the same for every application. We have LED plant lights designed specifically for multi-tier production, greenhouse
growers, warehouse farming, algae
production, and virtually any scenario in
which supplemental plant lighting is
needed.  Variations between models which
should be considered include beam
spread, mounting distance above the plant
canopy, energy requirements, and
included wavelengths. Let’s take a look at
how 12 popular LED grow lights stack up
against each other in the same 4’ x 10’
growing plot.  We’ll start with  the lowest
watt LGMIP65 light bar. To the right is the
most likely layout of the 14.4 watt IP65s in
our example plot.

  The 14.4 Watt LGMIP65 LED light bars in the layout above are designed to be mounted 7.9” above plants and run
                                                                                                              on less energy than any other model.  In our
                                                                                                              example, the lighting energy requirement would
                                                                                                              be less than 9 watts per square foot.  The
                                                                                                              initial cost works out to about 57$ per square
                                                                                                              foot making the 14.4 watt IP65 one of the most
                                                                                                              economical LED choices available as well. The
                                                                                                              14.4 watt is ideal for many multi-tier layouts and
                                                                                                              lab shelving applications where there is
                                                                                                              limited space between multiple layers. The 120
                                                                                                              degree beam spread is well suited to close
                                                                                                              mounting and wavelengths include 660nm
                                                                                                              red,  460nm  blue, and 10K white LEDs.

   In the same category as the 14.4 Watt LGMIP65 is the 28.8 Watt LGMIP65 LED plant  lights. Same wavelengths,
double the watts. The 28.8 watt is meant to be mounted 9.8 inches above the canopy and has a 120 degree beam
spread.  Energy requirements for the same plot would be just less than 12 watts per square foot. The initial cost of
covering our 40 foot plot would be less than
$65 per square foot. The 28.8 watt model is
another option for lab shelving and multi-tier
applications which require higher light levels
than the 14.4 watt provides.

  The LGM BlackStar would be the highest
watt low-watt LED option using 22.5 watts per
square foot. These can be mounted a little
further from the canopy utilizing a mixture of 60,
90, and 120 degree lenses for even coverage.
In our 4' x 10' example plot. The initial cost
would be approximately $57 per square foot
making them slightly less expensive than the 28.8 watt IP65 LEDs. The BlackStar model includes 6 bands- 630, 660,
425, 730, 380, and White 12000K UV wavelengths which are helpful in applications that do not receive sunlight.

                                                                                                                      The LGM Chrome series of LED
                                                                                                                  plant lighting is the first of the high watt
                                                                                                                  models.  The LGMCRM4 is the
                                                                                                                  smallest Chrome model offering high
                                                                                                                  power and efficiency. The patent
                                                                                                                  pending lens is designed to increase
                                                                                                                  both penetration and PAR output
                                                                                                                  including characteristics of a 30, 60,
                                                                                                                  70, 90, and 120 degree lens.  The Chrome
                                                                                                                  4-spot needs a minimum of 18" between
                                                                                                                  the LEDs and the plant canopy and can be
                                                                                                                  mounted up to 36" above your plants.  The
                                                                                                                  Chrome 4-Spot runs on 105 watts at full
                                                                                                                  power but includes an option to turn off
clusters to run the unit at 50% leaving the energy use somewhere between 11 and 21 watts per square foot.
Wavelengths utilized include 680nm, 660nm, 630nm, White: 12000k, Blue/UV: 425nm, and 460nm LEDs. Because the
coverage area of the Chrome model is better suited to our example plot- in this scenario, the high watt Chrome would
use less energy than the lower watt BlackStar model. Check back in our next issue to see the most popular high watt
models head to head. --AL
