Back in the late 70s/early 80s, we had a huge supermarket here called Fine Fare, (for our older UK members:, remember Fine Fare)?
Anywho, the whole store was lit with 1 KW mercury lamps, there must have been a hundred of them!!
This exact store is still here today, (now ASDA), but obviously without it’s mercs)!, but my point is here, can you imagine running a supermarket today, 7 days a week with a 100,000 watts lighting load!!!!, especially with today’s rip off energy prices!
It’s little wonder everyone is changing to LED, even if they don’t particularly like them, back in the 70s we weren’t paying ridiculous prices for electricity like we’re doing now, new installs of HID just don’t make financial sense today.
