Another shop light question

[Industrial Toys]

Any issues with RFI on LED fixtures/retrofit lamps and any issues with tripping ARC Fault breakers?

 

[grsthegreat]

Not that i have heard of, and ive installed alot of them on gfci circuits. I dont believe ive done a retrofit on an ark fault that i remember. But i dont see how it would affect an ark fault.

I have a few questions in regards to switching over my shop lights to LED and being able to see lol. My shop is 40x70 with 12' to the trusses with pre existing lights 16 total. They are situated in two rows, every 4th truss. I'm assuming the height of the lights/fixture makes a difference on what style. Everything is already wired so it won't be hard at all and I'm trying to decide or figure out my lighting options. I'm not wanting to put up gold fixtures but I also don't want the cheapest either. I just don't have any idea when it comes to this besides the fact that I want plenty of light. I will also put in a couple extra around the main bench/work area. For those that have did went to LED, please share your experience with different light set ups and what you would do differently if you started over. Also I'm just starting to figure this out so any links or pictures would greatly help. Thanks

1. High loft vs rectangular vs strips---would rather go high loft or rectangular
2. Is a high loft what is called a UFO style
2. Best to hang or fix to the truss
3. When it comes to lumens or watts, what should I be looking at or for

Any other suggestions are welcomed.

I have a similar sized shop but 18 feet to the eaves. I originally had 4 high bay sodium lights mounted about 15 feet from each wall. The electrical utility had a conservation program and they changed them for me to four T8 high bay fluorescent fixtures that use six T8 bulbs each fixture. Last year I changed the bulbs to T8 LED Luminous brand similar to these
https://www.costco.com/feit-electric-led-4'-replacement-glass-tubes,-4-pack.product.100482236.html

The LED bulbs are instant on, very bright, no buzzing, natural daylight coloured light, and use a quarter of the energy of the fluorescent bulbs. The fluorescent bulbs were a quarter the energy of the sodium lights, took about a minute to warm up, white light, and tended to flicker and buzz, especially during warm up. The sodium lights took several minutes to warm up to full brightness, were very buzzy, and had a very yellow light.

I have no regrets switching to the T8 LEDs, no RFI issues. I have a mezzanine with the same LED bulbs and a motion sensor switch. I had to change the motion sensor switch to one that used a mechanical relay switch. The original switch had a MOFSET and bleed off voltage/current causing the LED to never turn fully off and flicker in the OFF condition. I had to leave one bulb as T8 fluorescent to sink the bleed off until I found a better motion switch.

I definitely like the LED conversations for florescent fixtures, however if you don't already have the fixtutes I prefer the LED high bays (UFO style).

I've still a lot of T8's and T12's sucking up electricity so your statement of

a quarter of the energy

made me look it up.
The link you provided has bulbs that

Features:
4100K Cool White
1750 Lumens
Actual Watts Used 14

That's about 125 lumens/watt at $11.25@/TUBE
For reference T8's like I've been using are like 2400 lumens for 32 watts (75 lumens/watt) at < $2@/TUBE

And the AmazonBasics twin "tube" fixtures I've been hanging are rated at 4000 lumens for 40watts (100 lumens/watt) at about $6.25@ FIXTURE.

I'd love to see inexpensive LED's that use "use a quarter of the energy of the fluorescent bulbs" but they just are not there yet.

they are definitely not There yet. I only changed mine because i got the lamps for free....left over from multiple commercial relamping jobs. I would never have swapped out existing lights for leds because the payback time is still too long. The only rime i install leds now on my own place is when i install new light fixtures.

To me, that would add insult to injury. Replacing good old lamps for LED, thinking to save money and then the LEDs fail.

BIG difference from large and commercial installations to the little guys house or shop. For one, if you are that cost conscious, you turn off lighting whenever practical. A switched off circuit costs nothing! I feel just terrible, if I find out I left lights "burning" unecessarily.

I have (4) of these in my 36*48*14. They light it up PLENTY. Really don't need the under loft lights, or upper loft lights unless you really want it bright.

NICE.. I love your bright wall coverings. OH, to build a shop from new!

Staircase reminds me of that on the TITANIC.
