I am excited to get the new LED lamps this week.

I ran a power test on the old lights for 187 hours.

Here are my findings:

I used 28.84 KW

That is 150 watts per hour

or 3.7 KW per day

or 111 KW per months

At 8 cents per KW equals approx $9 per month for power

Now the LED use 40% less power

That is a saving $3.70 per month or $45 per year.

It will take 5.7 years to recover the cost of the new LED lamps.


If the new LED lamps help grow faster and better veggies then it is worth the cost.
