We just did a little head to head test of the BRICK by Western Technologies vs the Dialight.
CDI rebuilt 126 portable light carts for the Everett Flightline a couple of years ago with Dialights as the replacement for the HID fixtures that failed.
On a per cart basis with QTY of 2 fixtures per cart, this is what the power consumption is for an 8 hour shift using both lights.
Watts to KWH Calculation:
E(kWh) = P(W) x t(hr) / 1,000
DIALIGHT FIXTURE: 8 hours
1.368 kWh = 171W x 8hr / 1,000
Use for 2080 hrs = 355.68 kWh @ $0.10 per kWh = $35.37 per year per light x 2 lights per cart = $70.74 cost per cart *
*Carts are wired in parallel so one switch always runs two lights.
$70.74 x 126 carts = $8,913.24 per year in electricity
BRICK FIXTURE: 8 hours
0.712 kWh = 89W x 8hr / 1,000
Use for 2,080 hrs = 185.12 kWh @ $0.10 per kWh = $18.51 per year per light x 2 lights per cart = $37.02 cost per cart *
*Carts are wired in parallel so one switch always runs two lights.
$37.02 x 126 carts = $4,664.52 per year in electricity
It looks like we could save the Boeing Company 52% in energy costs in just this one area of light use, and have a longer life cycle with portability if we use the BRICK vs Dialight.
PS; 3 additional purposeful features/certification catagories to contrast BRICK over Dialight:
Portable-can be removed from cart
Wet Location-
Low Voltage-
