LED workshop illumination

Hi

I'm moving house and have a double garage for my workshop. Need to improve the lighting/insulation etc and wondered if anyone has experience with using LED strips like this :-

 http://www.ebay.co.uk/itm/Epistar-Quality-12V-2835-120-LED-M-600-White-Flexible-LED-Strips-20LM-per-LED-AU-/221603537858?pt=LH_DefaultDomain_15&var=&hash=item339899a3c2

I reckon about 1000 lumens = 100W incandescent. I have never used strips like this and I'm hoping that I can attach them to the ceiling without heatsinks. Not even sure if I would need a diffuser. Possibly lower output strips over a larger area may be better.

Any advice or info from someone who has tried this most welcome.

Best Regards

I got a reel of a similar LED's (5630 or something like that) and have mounted them under some cabinets shining on my bench. I don't know if the ones you linked to are a lot brighter than mine, but the strip I've got would not be bright enough to illuminate my workshop on their own (especially attached to the ceiling). They are great for under-cabinet illumination though.

I'll go out to the workshop and snap a pic or two of my setup.

Here we go.

I've taken these from the door looking into the workshop in the hope that the camera (phone) will show the difference and not compensate for the difference!!


1st up is a view through the door with no workshop lights on





Next up is just the LED's under the cabinets switched on.





Next is the LED's off and the main lighting (6 x 4ft flourescent fittings in 2 rows) on





Then everything switched on





Then a close-up of the LED strip





Hope this helps

Hi Tim

Thanks for the pictures - most illuminating  :bugeye:. The ones I have looked at just seem to have a sticky back for attachment, and as your picture shows need no heatsink or other stuff. Whereas you have fluorescent tubes for the main lighting I am going to try to do it all with LED's. Prices seem very reasonable at £5 for 1 metre or £16 for a 5 Metre length. If they are 20 Lumen per LED (2835 type ~ approx 180mW spec'd at 120-150 lumens/watt) and 120 LED per Metre that should be equivalent of 1 -2 100W incandescents. With a 120 degree output they should make for a well lit workshop  :thumbup:. 

Will order some, do tests, and post results. As we have not moved yet will likely be some weeks.

Best Regards

Yea, mine came with sticky back, made it real handy for mounting and the adhesive holds even when the LED's have been on a while and are a little warm

No heatsink needed for them, even after 3-4 hours they are just warm to the touch. And they are easy to power, 12V DC, the ones I got came with their own PSU.


I look forward to seeing what your tests show

Tim
