No no... I'm open to that if it makes comparative sense.

How bout this - Please point me to a specific fixture/ lamp combo to purchase as a test, I will order that, and THEN comment back after visual comparison.

That makes it easier for me, cause so far too many options in your approved list.

OK ?

Yes. I see the WEN-T8-4FT-18WF is out of stock.

I've been playing with DIALux… when I first imported the IES of the CLX L48 it asked me to verify certain parameters. Do I need to make any changes?

I tried the .LDT file and it didn't ask for anything.

I asked ProLighting to send an IES of their 3 lamp TechBrite and they mentioned they can manipulate the lamp and lumen count.

What's the best way to model the 3 lamp Techbrite fixture?

bmwpowere36m3 - This is a light fixture thread, not a Dialux training thread. Just accept the defaults. I'm not getting involved in training as Dialux has tons of videos covering everything you could possibly want to know.

Wow, Seriously? :wtf: Considering the massive amount of free work I've done on this forum, that is so not justified. No good deed goes unpunished.

Thanks Platonic, I appreciate your lighting knowledge when I needed fixture and tube help. It is bright in my garage both downstairs an upstairs. Thanks again for the free information.........

Platonic - I would be breaking up these in switched lighting zones, but asking how many of these double lamp fixtures can be put on a 20 a #12 wire breaker ?

I did work as Electrician, but retired 20 yr ago from that, and hear that LED fixture load needs to be figured "Different" than what I knew.

Thank You again, Marc

Marctrees - You don't need 20A #12 wire. 15A #14 is more than enough for the whole setup. 15A x 120V = 1800W. 60 Bulbs x 18W = 1080W.

I think I will order two of the fixtures / lamps you spec'ed for comparative test to my in house CFL's.

At the very least, I will use them on my two head doors when open, if not the whole job

Any recommendations on some low profile fixtures/bulbs with CRI 90+ and wide beam angles? I have a 18 x 20 garage with an 8 foot ceiling that I would like to light up and do some air brushing in one corner with a booth and other projects on my bench against the back wall. I have a single 4 ft fixture in the center right now and it is just not cutting it.

Thanks. That is helpful for sure. I actually use some LED strips from waveform. I didn't realize they came out with LED tubes. Do you think running these in an open fixture would better best? I could try and find a low profile fixture with a diffuser but I'm not sure if that would adversely affect the color or output.

PCMusicGuy - Unless you're averse to the appearance of a basic 2-lamp 4ft strip light, I would not install the lamps in a fixture with a diffuser as it will only reduce the light output. For even light output, use only frosted lensed lamps. To answer your question - typical acrylic wrap fixture lenses will not affect CRI.

Max fixture center to center spacing = (Ceiling Height - workplane) x Spacing Criteria
(15' - 2.5') x 1.25 = 12.5' x 1.25 = 15.6' max

≤ 15.6' is acceptable.

OK let's try to smarten me up. I have these hanging down from my ceiling about 2'. Honestly I think my coverage is a little spotty. I'm not sure exactly what my spacing is, as I am at work now.(it's less than 15.6') But maybe it would make sense to raise them a little?

What is the definition of the workplane? How far off the deck typically work would be performed?

Thank you very much for your expertise!

Dragster Racer - Yes, your description of workplane is accurate.
I selected a Lithonia fixture with similar output here (link to Visual Photometric Tool preloaded with 20,000 lumen linear highbay IES file).
After clicking that link, follow instructions here (link).

greasyfingers01 - Sorry, can't recommend any bulb or fixture from any company that can't be bothered to invest in NRTL certification (UL, ETL, CSA). None of their specs mean anything since they can't be verified.

Edit: FYI, it wouldn't pass UL as it's missing the reflector which segregates the wiring comparmtent from the lamps. Similar UL Listed fixtures are slighter higher priced, but you get all the components.

CJseven - DOB? No idea. All I can think of is Date Of Birth, which makes no sense.

Plus, this is another no UL, ETL, or CSA Listing fixture.

Sorry, I wasn’t really interested in the lights I know they are cheap junk. It was the DOB that I had not seen before that really caught my attention.

Platonic, I didn't think of looking for their certs. Thanks for pointing that out. When they come in, I'll check them out for a UL certification if none, they're going back.

I've been wanting to go with a vapor tight fixture due to my relatively low ceiling height for bulb protection, and keeping the fixtures clean more easily. I've busted a couple bulbs over the years. Will I loose lumens with a clear lens over them? Fyi, my shop is used for automotive, general fabrication, and machining.

Guys, I ordered nearly 40 of the Maxlite housings for my new construction garage and basement. Electrician is coming this week to do the final electrical work for the house, which includes mounting these fixtures. All locations have 4” round boxes in the drywalled ceiling and I just realized these housings are narrower than the light boxes. What are you guys doing to hide / cover the ceiling boxes so there’s no exposed gaps on either side of the housing?

A 4" round box cover with a 1/2" knock-out should work fine.

Confirm with your electrician for code requirements otherwise.

https://www.homedepot.com/p/Slater-4-in-Plastic-White-Round-Ceiling-Box-Cover-4RBCW/304271231

I talked to him about it today. He's told me numerous times in the past that my county's inspector is beyond ridiculous to deal with. He said worst case, for the inspection we can just mount a cheapo standard light fixture in each space and put plastic covers over all the other light boxes. Then after inspection, I can put them up however I want / need to.

I did find some 4-3/4" dia metal, thin (flush) covers at Lowes today that would cover the entire cutout. I'd need to drill a hole in the center for the romex to pass thru tho, not a big deal.

I like the plate you linked. It would likely recess into the drywall cut out. Most of the boxes are 1/8" to 1/4" recessed into the drywall hole. I guess if I did use those, I could fill that gap with drywall mud and end up with a clean, flush look. Additional work.

I like these housings, but if I'd known this beforehand, I'd not have ordered them. :(
