Shop Lights

[kingscreen]

We discovered during our conversion that we really only needed a bulb for bulb replacement over the presses.  Because LEDs are so much brighter and cleaner light, in most of the common areas we only put up a single LED instead of two.  We noted that a single LED was brighter than two fluorescent!  The savings will be significant.  We chose 48W which replaces our old 75W fluorescent (per bulb).  This equates to 36% LESS electric use for double bulb fixtures and 68% LESS in the fixtures that we only put a single bulb in.  Pair that with brighter, BETTER light, it's been well worth the investment already.

So everybody likes the LED shop lighting then and feels like there is good ROI on converting?

Can you source LED retrofits that put out correct lighting?  Everything I have seen is good 'ol "cool white".

We do use D50 5000˚K lights in select areas but they are T8.  The rest of the shop lighting is good but not perfect, i.e., the little D50 swatches on the back of the pms book aren't exact like under the true D50 bulbs.

 We were just getting ready to replace all of our fluorescent bulbs throughout the whole shop we do this yearly, our power company supplier AEP send a contractor out and he is going to change out all of our fluorescent forefoot Bob's to 5000 Kelvin LED bulbs and remove all the ballast in all 54 fixtures  at a cost to me for $600 last year I paid $500 for bulbs and ballast replacement and I did all the work myself call your power supply company and ask them for the department to help you reduce your energy costs or consumptions if you can't find who to talk to give me a call I will give you our contractors phone number they work for power companies all over the country your bill is determined by the number of fixtures and number of Bulbs.

HAHA, I was thinking that man, that guy is rambling...but it makes sense.

When we did ours there wasn't much available.  Some power companies will only give you a rebate.  It's worth checking into though.  And yes, 5000k is what you want.  The pantone swatches aren't perfect, but they are pretty darn close.

So how close are the 5000k LED tubes to true D50?  I couldn't find any except on alibaba that advertise a D50 output.  The ones in our office, which is a big light box essentially are fluoro T8 and cost about 137 per fixture.   

Are there any Energy Star qualified tubes that are "close enough" for the shop floor?

dunno how close they are, but seem to work OK for us. Order a couple of bulbs and give them a try if you are that concerned.

I'm not super picky but my ink dude gets bummed out a lot matching colors on the shop floor and then bringing them into the giant light box we call an office.  There's a difference between 5000k and true D50 for sure, not that exact lighting is a necessity in all areas but extreme differences can frustrate things.

I have more fixtures to buy and will give them a shot via our state's rebate program.
