High bay light positioning?

[wantacoe]

I ordered my High Bay lights about two months ago. I was told they are floating around in the Pacific but they hope to ship them by Mid January. I know the lights "spread" with the reflectors from side to side but do the ends basically just shoot straight down? Do the have to be at the end of the ceiling to get light against the walls? I know my wording *****! lol

High Bay lights should spread at a narrower angle than other fixtures. That being said, different companies define "high" differently, some high bay fixtures are not really high, and many people mistakenly thing their 10' ceilings are high... (A good representation of a high bay installation would be at your local Home Depot or Lowes.)

The best thing to do would be to check your manufacturer's web site. They should give you specifications for the mounting height for the fixutres and how to lay them out. If your ceiling height is off from their spec, you should be able to extrapolate the placements.

This is the lights I ordered. I bought these on a recommendation from Platonic Sound a couple years ago. That is how far behind I am. My ceilings are 15'. Shop is 40x50'. 16 lights. https://www.ledlightingwholesaleinc.com/DM-HB2-110W-50K-p/dm-hb2-110w-50k.htm

Wantacoe, the light is delivered from that fixture from side to side at 120 degrees. Yes, it also delivers light outward at either end, but the beam is technically not measured that way. (Well, it is, but the information isn't commonly reported). The beam will be about the same in this direction, although not as powerful.

cybrdyke, So if I spaced them 4' from the end I would probably have sufficient light say at a work bench that is against the wall?

I had those lights in my garage.
The pattern doesn't have a hard cutoff.
At 12 feet height, and 1650 ft2 I had twelve of them. Used 3/4" conduit off the boxes for mounting.

Ended up removing them after about a two years. I just couldn't live with the loss of overhead clearance.
Here's the listing where I sold off all my stuff.

Lot of "like new" and "new" High Bay LED fixtures

***CONSIDERING ALL OFFERS*** I am offering the following LED fixtures as a Lot. They will be coming down from my new garage in the next 8 to 10 weeks due to clearance issues. I have them pendant mounted but need more overhead height in several places I am posting them ahead of time in order to...

And, BTW, the guys at the place you bought them are not people I would ever want to deal with again.

I wouldn't trust anything they're telling you for delivery times.

Yeah, you should have, but wont your shadow be in the way? That's why lots of folks get task lights or a lower hanging bench light.

Round highbays shouldn't have this problem. Looking at UFO type things eventually. Just have wall and task lights for now... 19.5' ceiling.

I would just evenly space them ( on your 40' dimension lights at 5', 15', 25' and 35') I think you'll have plenty of light and minimal shadow. But, you can always add some task lighting.
