This is a question we often get asked by our customers–how much electricity is being used by Spectrum King LED grow lights? With state and municipal governments cracking down on energy consumption, it’s not inconsequential that our lights are pulling very little at the wall and are, in fact, acting as part of the solution to an ever-growing problem.

A simple calculation can determine what amps are being used at the wall:

DC Watts to Amps calculation:

The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V): I(A) = P(W) / V(V)

So let’s say you find out that you only have 208V.  How do we calculate this?

W(SK600 = 650Watts) / 208V = 3.125 Amps (Always best to round up for safety, call it 3.2 Amps)

Spectrum King LED power consumption:

Mother’s Lil’ Helper 100 Watt Veg Light
@ 110V – 0.83 A
@240V – 0.45 A

Coset Case 100 Watt Veg and Flower Light
@ 110V – 0.83 A
@240V – 0.45 A

@ 110V – 3.6 A
@240V – 2.0 A
@480V – 0.91 A

@ 110V – 5.3 A
@240V – 2.9 A
@480v 3 Phase = .79 A

Taking an active role in knowing how much power you use in your garden is the first step in reducing your carbon footprint.
