Led light panels

I had three, all three failed quite quickly.

I'm lost now, I may just buy a couple and see what I think of the colour before splashing out on 8-10 of them

I think the colour we see will vary person to person as we are not all the same. The colour charts are a guide to what is expected.

For workshop use I prefere cool lighting around 6000k which is more like working in daylight. I don't see 6000k as "blue" in itself but it can enhance the blue items. It depends upon what feels comfortable to each of us, when I was younger I could easily work at 3000k but my eyes have changed over the years and 6000k seems better for me to work in now when possible.

My little 8ft x 10ft workshop has a pitched roof, and was lit with two twin tube fluorescents.

In 2020, a friend installed eight 600 x 600 LED panels in his workshop which had a flat ceiling. I was really impressed with them so decided to replace my fluorescents with a couple of panels. I fixed them beneath the rafters in wooden 'boxes' that I made. What I hadn't appreciated was that the LED panels wouldn't 'flood' the room with light in quite the same way as the fluorescents, so no light was radiated above the level of the panels. Hence, anything stored in the rafters or on top shelves was in complete darkness. The net result was that I left the panels in place, but re-installed the fluorescents, so the LED panels ended up being in addition to, rather than in place of, the fluorescents.

I've attached some rather poor quality pics of one of the panels.

First pic: The panel housing 'box'.
Second pic: The hinged LED panel in situ.
Third pic: The panel ready for use.
Fourth pic: The workshop I built from scratch in 2003, and roofed with felt shingles, which are as good today as when fitted.

Hope that's of interest.

I've noticed some say they are edge lit, is this to be avoided?

Our previous QLED tv was edge lit and the screen worked perfectly for over 5 years of heavy usage. Then the LEDS on one edge failed and only half the screen was illuminated. there are light diffusuing materials that spread the led output across the screen to give effective and even lighting.

With an LED panel it relies on the quality of the components used and how the driver circuit is rated - if components are run at maximum rating (or even over-run the life to failure will make it likely fail in short order.

How are you guys mounting the recess panels? Do you have the full grid ceiling, or are you just sticking single panels up?

I made some wooden 'brackets', a simple wooden block as a stand off from the ceiling with a slot on the side for the edge of the panel. They weigh next to nothing.

Yep, two bits of scrap with a rebate down one side.

A bit cheap and passé tech these days, the non-edge lit ones are better.

That doesn't make a lot of sense as 6500k is much bluer than 4000k.

Or this is a more practical illustration (but doesn't go as blue as 6500)

Was just about to post the same!.
