Lithonia Lighting CPHB 12LM MVOLT 40K Compact PRO LED Bay Light, High Bay, 12000 Lumens, 4000K Light

This is a nice footprint at 14" long and really light sup the space of my 40x40 pole barn. At approximately 13' high and 13' spacing, 9 fixtures really do make it seem like daylight in the shop. I love that they are genuine Lithonia fixtures. Great price for exceptional product.

Good Light.

Love these lights. Installed in our open office warehouse with high ceilings and they’re perfect.

This are great lights , I bought 3 of them from Lowes and need three more so I ordered from here. The look was the same and the 18LM but these are 50k and the one from Lowes was 40k . I do like the 50k so much better.

Do not buy, waste of money and time…

You know those old 4' fluorescent fixtures you've seen in so many garages? The ones that flicker and hum when it's cold? That's what my buddy had in his garage when we replaced it with this. He was going to get new bulbs for the fluorescent, and I was like...why not go LED?So we yanked that old steel fluorescent fixture out and wired this up. When you look at it in the pictures, it almost looks like the led strips are adjustable, but they aren't. So if you look at these and go, hey, those look like they pivot...well they do have that appearance, but they do NOT pivot. But we wired it up and it didn't really matter that it's not adjustable, it's so bright. As in, if you come in from the dark and turn it on, it hurts your eyes if you look at it.If you were to ask me, how does it compare to the old fluorescent fixture? There IS no comparison, beyond to say it's 2-3 times as bright as that fluorescent fixture on it's best day with a 20% overvolt. Its so bright, it makes you want to take the old fluorescent light out of the dumpster you just threw it in just to hit it with a hammer and ask it "Why? Why were you so DIM???"We didn't do that, by the way.Trust me when I say, if you go into your workspace and turn on a set of old fluorescent fixtures, you need to invest in one of these babies. Throw those old fluorescent fixtures away. It's time to move on.

Look for my bedroom light I am more interested in a warmer color temperature but when I get in a work area like my woodworking shop or garage, I want all the brighter light I can get. So, for comparison a standard four-foot fluorescent bulb puts out 2850 lumens per bulb. This fixture puts out 12,000 and not only that it is at 5k on the brightness white balance scale.This fixture is designed to be put on a high ceiling, but I have another fixture at 20,000 lumens that is just like this one in my garage, and it illuminates the whole garage which is a 2 car in width. This one is way more compact than that. The fact that it is LED is huge because the amount of light it puts out compared to the electricity it uses blows the doors off of fluorescent bulbs. Plus, LED's have a usage life that is many times as well. I got so tired of replacing 4-foot fluorescents in my shop, garage, and attic I wound up throwing all of them out. Actually, I sold the shells as a pile.I'm going to be using this in my storage shed. It's a 10' x 14 foot. Just one of these fixtures provides a lot more light than is needed. It's going to be great to be able to see what I am doing even during the evening hours.

I am very picky about color temperature when it comes to LED lighting. 4500K to 5000K is my preferred sweet spot for general purpose lighting and especially for task lighting. A more comfortable color temperature for around the house is 3500K to perhaps 4000K. Anyways, I have seen a lot of manufacturers claim 5000K in particular but in reality it is around 7000K, which I find intolerable. I can happily report that this light delivers an excellent color temperature and seems very close to 5000K to my eyes.I have included a picture of my temporary installation in my workshop. After deciding that I liked the positioning of the light, I went ahead and installed proper conduit, wiring, and mounting. If you are considering mounting this unit up high (as it is intended), I would highly recommend you consider 15K Lumen, 18K Lumen, 24K Lumen, and 30K Lumen models. They will give you more flexibility and more light should you discover you need it. The 12K Lumen model I tested (as well as all of the other models I just mentioned) have the ability to dim, when simply wired up to a 0-10V DC dimmer! You can buy the big dog 30K Lumen model and dim it down to the same brightness level as the 12K Lumen model, all while increasing the life of the light fixture. Need more light that you originally thought? No problem!When it comes to build construction and design safety, it is better than I expected. I have very high standards, since my history when it comes to high bay lights are luminaries wholly manufactured by Cree. I was impressed what this $90 unit offers considering that the Cree units I have previously dealt with cost over $800 per unit!
