I found this using google:
Near the bottom it says: "The new store also features many green
initiatives including LED lighting throughout the first Sainsburys
in the country to be built with such a feature."
If it doesn't open until next week, how did you get in to take the
Doing some IT work.
If it is LED it's very good, I had no issues with the lighting level,
uniformity, or colour temperature. Andrew Gabriel has just responded
to a post of mine in another group, I'll ask him to come here and give
his expert comments.

Yes, exactly like that and I doubt if they will resist the temptation
to use some them as signage.
Here is another angle
What the camera can't show is just how much brighter they look from
directly underneath. The distent ones are very easy on the eye.

don't think a T8 would fit at least not without the box being very snug
and you need space around a tube to bounce the light that is being

thinner tubes would fit with space. With such a distant view its hard to tell much detail, but there are certainly ways to redirect the light from T8s or T12s without space by the side, such as by reflecting light above down into the edge of the sheet glass.
Wondering if, regardless of the actual light source, they are really an
improved diffuser? In our JS the lights initially appear to be good and
(other than the hanging down bit) similarly fitted to yours and at a
similar height, etc. The light down the aisles quite well, but the
ceiling has a much less even effect than yours.
Also, it would be a damn site easier to wipe down a bit of plastic than
to try to clean a classic diffuser.
Maybe the same fitting can take fluorescent or strip LED? That might
need an improved diffuser.

I've been very impressed with some of the LED replacements for fluoro
tubes that I've seen. In fittings with a shiny reflector, they've been
fitted pointing down, and I wondered if they would be better fitted
pointing upwards to reduce direct glare (they're *bright*).
I think that the optics of LEDs lead us to think they are brighter that
they really are. We are trying to compare a bright small source (LEDS) with
a larger and more diffused source (Others). The real test I guess is to
compare the light reflected off the illuminated surfaces over the
