Have you read that thread I linked to and watched my video?
That is a single panel in a 30sq m workshop (building site...) and its very bright. I’m planning on putting in 6 and I reckon that will be bordering on the brightness of a white supergiant!

Maybe just about but it is also about the effectiveness of the light ie the colour temperature and the directionality of the light.
The figures I put in the earlier post do not support a massive increase in efficiency for LED over fluorescent tubes but the life is better and the capital cost higher as is the replacement cost. I can find no data for the efficiency and life of the switch mode power supplies used by LEDs but generally speaking the high voltage capacitors used in SMPSUs, LED bulbs and compact fluorescents are the main source of failures.
I use led lighting in my bookcases and the Christmas lights and have had 3 SMPSUs fail in the last year and have resorted to a linear power supply dug out from the junk box ex NetGear router.
If you are keen on LEDS then why not buy one to try and compare alongside flu tubes?
You can buy an awful lot of flu tubes (£3 58w T8 x 5') for the cost of those LED panels though.

What the h... is that ?
Mark Hancock wrote:Thanks Bob. That's exactly the conclusion I've come to; try one out and see what the difference is.
I've been very wary of all these changes with lights over the years recalling all the hype about the energy saving bulbs when they were being given away by the utility companies and how they were so long lasting. I've had to replace more of them in the last 10 years than all of the filament bulbs over the previous 25 years.

Roger, tried using TLC Direct but they wouldn't ship to Worcester and picking up from them wasn't realistic so went with LYCO whose service was fantastic - ordered Saturday, delivered Monday....
Thanks again for all the advice and help.
