Copper Nickel Alloys

Those are alloys of chemical composition copper + nickel with addition of manganese with a low resistivity (from 231.5 to 23.6 Ohm. Mm2/ft).
The most known, CuNi 44 (also called Constantan) presents the advantage of a very low temperature coefficient.
Their advantages are the following:
Very good resistance to corrosion
Very good malleability
Very good solderability

High quality LED Aquarium Light good for coral growth

Help the coral reef grow 


Advantages:
Economical Long life,low power consumption,high efficiency and cool operating temperatures.
LED is a cost effective choice for your Coral reef/aquarium/fish tank needs.
 
Long Lifetime
Recommended useful lifetime of 50,000 hours for LED lights the equivalent of burning a light.
18 hours/day, 365 days/year for seven years and seven months.
 
Energy Efficient
To save 70~85% on power over HID lighting, plus reduce or eliminate power consumption.
No need extra blowers and air conditioning systems.
 
Coral Reef's Friend
98% of the light emitted from LED were absorbed by Coral and other water plants.
Only 10% of the power used and about 35% of the light generated by metal halide lamps is useful to plant growth.
 
Low Heat Output
LED lights produce very little heat. In most situations, no special ventilation or air conditioning is needed.
The temperature of our LED Lights are controlled by normal residential AC/heating and a ceiling fan.

Warranty:
Warranty: 3 years 
Safe Voltage: Low voltage output to ensure safety. 
one led burns out won't effect the other chips
we will always provide the Best Price and excellent quality, most important, service always for you. Any problems, we will solve it to you within 24 hours
