Nice! BTW that's the perfect basement for a bunch of fluorescent lights. You'll get a lot of light. Smile

Yeah I could see a couple of 4' lights being installed here, or if you're feeling ambitious some streetlights to complement the signals.

I'm eventually swapping all lighting to the flourescent tube style LED units.

Just going to let you know now, those LED "fluorescent tubes" are terrible. If you insist on using LEDs, just installed LEDs in the existing incandescent fixtures. Those LED tubes sag and fall out of fixtures, they're glarey and have spotty light output, the cost a ton, and they look ridiculous like some redneck rigged them up lol. Plus, the fluorescent tubes are actually MORE efficient than the LED tubes. The LED tubes use less energy but if you look at the lumen equivalent, a 4ft F32T8 gives 2800 lumens on average. Most LED retrofit tubes I've seen give around 1800 lumens, which is about the same as a 100W incandescent. Absolutely shameful.

Stay clear of the crap at Lowe's and Home Depot too. Those are the worse fluorescent fixtures on the planet and they still charge top dollar for them (highway robbery right there!). They use crappy residential grade ballasts that drive the lamps at 60% of their potential (aka "energy-saver" ballasts) and have low power factor, which means they use more current for the same amount of power draw (you don't necessarily get billed for low power factor, but it means you can't use as many fixtures on the same circuit as you can with HPF). Commercial grade fluorescent fixtures have (slightly) higher quality ballasts that drive the lamps around 88% potential (considered the norm, though I always go for high ballast factor, which drives the lamps at around 118% potential) and they are high power factor, which means less current drawn.

To be honest, they don't really make rock-solid fluorescent lighting anymore. They made solid fixtures through the 90s but the ballasts have been crappy ever since they banned PCB capacitors around 1980. Pre-1980 fluorescent fixtures were excellent. Nice and bright lamps, rock-solid fixtures, and they would last FOREVER! Modern fixtures often fail before the first lamp change, which is asinine IMO. Just make sure you don't waste your money. I know you're not much into fluorescent lighting so you might be fooled by the LED crap. But that's all it is- crap.

It took me 3 years to find my good LEDs for the hall, the driver has to be external to work and last good. Then I used HO for some new areas. You see the building my dad owns was a AAA class sprinkler system so when the LEDs go up in flames we will just have a massive flood LOL
the average home with sprinklers is BBB+ class and I don't think you have one so yay no

Huh? Sprinklers? ...what are you talking about. As for LEDs I already have recessed and eyeball fixtures throughout the house with LEDs and they work great. I am not sure exactly what I will put in the basement. Now its a mix of incandescent and CFL. I know most here poopoo on LED. I think they work great and the technology improved greatly in the last 10 years. Just my opinion...I worked several years for a company that built LED lights.

The incandescent LED retrofit lamps that go in regular 120V medium base sockets are fine but the ones designed to retrofit into T8 fluorescent fixtures are crap. The fluorescent lamps achieve better LPW than the LED tubes! LEDs have improved over the past few years for sure but they are definitely not the "universal" light source that they're claimed to be.

I have several 1940s-1960s F40T12 preheat and rapid start magnetically ballasted fixtures and they far outperform any modern fixture. Sure, they use a little more energy but at the benefit of better reliability. Those lights will probably outlive me and I'm 17 and they're already my parents' ages and some of my fixtures are my grandparents' ages! LEDs will not last you 25 years. That's a flat-out lie and the manufacturers all know it is. It's just a gimmick to justify the higher cost (aka higher profit margin) of LEDs. It's all a big consumerism game.

My job is Sprinkler systems I only work on AAA (100% can be on) class systems, LPS-E is way better than LED
Mike: 100% RIGHT! LED is a lie oh,Did you know the providence place mall is a class BB- Shocked that is like 65 on a report card Only 1% of it can be ON at a time ! or massive presser drop
streetlight98   [Jun 25, 2015 at 09:50 PM]
Hmm I never go to the Providence Place Mall since I refuse to pay to park (plus Warwick Mall is closer to me) but it doesn't surprise me that they skimped on the fire sprinklers lol. The upper level of the Votech Building at my school doesn't even have sprinklers! The lower level does but I don't see any upstairs unless they're above the drop ceiling. Don't they have to be below the drop ceiling though?
traffic light1   [Jun 25, 2015 at 11:58 PM]
Oh no they are " melt a way " drop ceiling tiles, they melt at 155f the head pops at most likely for a school 155f, at my building they pop at 168f. Now it is possible to only have some parts of the building sprinkled and not others, School in Pawtucket only has heads in the basement here the class rooms only has one exit this means it has to be AAA class non air and it is. I have to put roof sprinklers in soon lol at this other location
