So, I’ve been slowly putting together plans in my head on creative ways to replace some old fluorescent lights in a workshop. The space is a probably just over 300 sq ft, with a high ceiling. Lots of light is going to be necessary given some of the intricate work my father likes to do in there. At the moment, there are two 4ft fixtures overhead and some other fixtures strategically placed in other areas for more light - like over the secondary workbench and some tools. The issue is the main, open area of the shop is just lacking good lighting. We need more LUMENS!! J)
My Plan
I envision something like 15000 lumens to light the main part of the shop. I plan on using some of the larger chip LEDs similar to these…LEDs on Amazon
What I’m not sure of is how hot they get when running at full wattage (the above LED is rated for 12V 1A) and if an aluminum sheet would be sufficient to manage heat production - gauge to be determined…
If I use the LEDs above (or something similar) I plan on running 3 “banks” of 6 LEDs @ 12V/1A, with each “bank” being driven through it’s own converter. That should give me about 15-17000 lumens. (factoring in losses - LED crapshoot and true output #s)
I suppose the biggest concern I have is safety and reliability in the converter I select for the job. I’ve seen several “brands” and designs (mostly Chinese of course), but since I have no experience running these, I don’t know if they’re good for continuous use at/around their rated specs or if I need to be barking up another tree.
Here are the two designs I’m used to seeing:
and
I know this isn’t necessarily the most cost effective solution, but it’s a project I can do with my son and his grandfather. Something different I suppose.
I’m open to suggestions, comments, or thoughts.
