LED vs fluorescent lighting in a supermarket

LED vs fluorescent lighting in a supermarket

Click to view full size image

This supermarket, at the time of the photo, converted some of the fluorescent strips to LED. You can see the LEDized fixtures have the lamps in the center, while the fluorescents look "off centered" because they are delamped on one side in the aisle areas to save electricity. Note the floor looks much brighter under the LEDs than the fluorescents. They however are much more glary than the fluorescents. I believe the strips are Cree models. Sorry for the sideways pic btw.

I don't like LEDs for general lighting. They look weird to me.

Aw man... I was hoping that T5s were as far as it was going to go but apparently LEDs aren't just replacing fluorescents in freezers... LED tubes are HIRL (high-intensity rope light) lol

Please check out my newly-updated website! McCann Lighting Company is where my street light collection is displayed in detail.

I heard that this store tested some T5s when the others were still T12 before doing a full change to T8 about 12 years ago or so.

May all the great lighting technologies have their place in history.

Yuck! A couple stores in my area are "testing" LED replacements for their 8 foot T12 fluorescents. Very glary and boring. Probably wont last a year.

Preheat Fluorescents forever!

One of our big department "stores" here in Moonah, Hariss Scarfe's has just done a total re-fitout with L.E.D. tubes and luminiares. I should get some pictures. They look very similar to the old 840 tubes there before except they fire the light downwards while the top half of the "tube" remains dark. The Lux levels on the floor look similar as does the CCT and CRI, so the L.E.D.s are getting better at mimicking these things.
I'm interested to see what the long term reliability will be though. I have already seen one led shoplighter, the sort that replaces a HQI-TS 150, dead in a battery shop here. It apparently failed two weeks after install, when they installed eight of the things. I assume it was redeemed for a new one and it has been replaced. Would have loved to strip the failed one down to see why it died after such a short time though.
Hobart city and Glenorchy councils have been "banging on" in the media about total conversion to L.E.D. streetlighting in two years...what about all those HPS Roadsters they have been installing for the last ten years or so and still not quite completed yet....what makes 'em think they can fit the L.E.D. Lanterns/Luminiares any faster than the Roadsters! Geez, pencil pushers think we a patsies!

If you want HALF the light of fluorescent, with the glare giving the illusion of the "same brightness" as fluorescents, then go to LED. There are a few stores with them here, and I now refuse to patronize them because they are harsh, even the "white" ones that look like fluorescent tubes and not the clear ones which are HORRIBLE, and they make me queasy and s dizzy---the high frequencies are even worse with LED's! My MS and LED's don't like each other. I am afraid LED's will end up KILLING me---literally, as I patronize fewer stores because of LED's w either in the store, the parking lot or BOTH, I stop going because of principal. Eventually I will literally starve to death because I won't be able to get any food dud to my refusal to patronize LEd lit stores! Thus, they are gonna kill me I fear! and now they are going to mostly retrofit LED tubes that run on existing electronic T-8 ballasts, further making the high frequency agony I go through even worse---my sister actually replaced 8 foot T-12 2 lamp strips in a local parking garage with 8 foot 4 lamp tandem T-8 ballasted strips with those crappy CREE or Philips (ugh!) retrofit to existing ballast tubes, as she can't even get the ones that connect directly yo mains power anymore---which means an already far less efficient than fluorescent lights source is not even LESS efficient due to ballast losses, as well as maintenance issues because of ballasts that are there for no reason at all! Give me a pitch fork, as the SH#T is getting DEEPER and DEEPER, folks! Basically they replaced working good fixtures with fixtures they don't NEED but since they now only make LED tubes to run on existing electronic ballasts HAD to be purchased---of course the owner of the building got it shoved up his A$$, but that is GOOD---he is a PR#CK anyway and a tightwad, and YES these POS lights were subsidized by good ol' "NYSERDA"--New York Energy Research and Development Authority---YUP a big bureaucracy! I hope the LED's puke and take out the electronic ballasts and the people have to use their headlights and flashlights! That would make my DAY! JUNK!

This store has since converted entire store to LED.
