No dangerous metal 240/120 volt lights. White case material absorbs heat from LEDs.
GEM5® lights are the very first lights ever designed just for algae scrubbers and seaweed cultivators. Because of
the very wet and splashy environments that waterfall scrubber lights must operate in, and the underwater
environments that some upflow scrubbers must operate in, these GEM5 lights are made with a high tech material which
not only seals out water but also removes heat from the LED so that it remains at the proper operating temperature
in any environment, submerged or not.
Put some GEM5 lights on the outside of a refugium (shining in), or on the inside of the refugium (in
the water), especially at the bottom (shining up).
If you want the lights to be easily removable, then the
mounting lugs on each end of a GEM5 light can be suction cupped (included) or screwed to a surface, and the light
can then be removed easily by just lifting up one end and sliding out the other. The GEM5 can be attached in either
direction: With the LEDs facing the glass (shining through), or with the LEDs facing away from the glass.
When facing away from the glass (and above the water) the raised-letter logo keeps a small distance between the GEM5
and the wall so as to allow cooling air to circulate there.
Each GEM5 light uses 5 real watts (volts X amps) for the power; it does not "say" 5 watts but only use 3 watts like almost all LED grow-lights do.In other words each light is a 5 watt heater. And because it uses real
watts, each GEM5 light puts out the same algal-growth illumination that a "larger" 10 watt LED or 20 watt CFL bulb
do. The GEM5 is pure deep red 660nm (nanometer), which is the primary growth spectrum for macroalgae (seaweed),
and is also easier on the eyes when you have to look at it.
The power supply for the GEM5 is a fully isolated, low-voltage, LED power supply that is CE, UL, Canadian UL, and
FCC approved. One power supply can power 1, 2, 3 or 4 of these GEM5 lights, using the 4-plug connector included. Any
of the 4 plugs that are not used are to be capped off with the included caps. With 4 lights, you are getting a full
20 watts of illumination output, which is the "equivalent" of 40 watts of regular (especially Chinese) grow lights,
or 80 watts of CFL bulbs. And it's heating the water at 20 watts too, if it's in the water.
The real beauty of a GEM5 light, however, is it's all-environment capability. It's patent-pending case is a solid
(not hollow) high-tech material which not only completely seals the LEDs when under water, but also removes heat
from the LEDs when above the water. This is very unique because normal resin or silicone would trap so much heat
inside that the LEDs would burn up. The high-tech material used in the GEM5 means the light requires no cooling fans
or heat sinks when operated in the air, and requires no waterproofing when operated under water. Matter of fact, if
you have 4 of the GEM5 lights (with one power supply) you can put 2 of the lights on one side of your refugium in the
air shining down, and the other 2 lights on the other side of your growth in the refugium shining up. And this includes setting the lights on
the bottom of your sump so they shine up from below! Don't try that with your Chinese grow lights.Also know that other brands of refugium lights have to reduce their power when out of the water so they don't burn up.
The GEM5 lights are the standard lights for our RAIN, SLIP, and largest DROP model scrubbers.
Lastly, since each GEM5 light consumes 5 real watts just for illumination, it can be used as a heater when placed
under water; so you can heat and filter at the same time. Using four lights (with one power supply) will act as a
real 20 watt heater.
These GEM5 lights and power supply come with a 1 year warranty.
Can be shipped to any country; you can find shipping costs by using the
shopping cart; be sure to click "display rates". If you don't have a zip code, enter "zip code"
instead. Note that shipping outside of the USA will probably require you to also pay an import charge when
it arrives. We cannot mark it as "gift". The lowest cost (but slowest) foreign shipping is generally USPS
First Class Package International, but USPS Priority Mail International is faster and has tracking and
insurance. The size of the shipping box is 11 x 7.5 x 5 inches, (28 x 19 x 10 cm).
