Is anyone aware of a zwave 450W LED dimmer? most I see are 300W or less. Looks like Leviton had one but it is now discontinued. All my stuff is currently zwave but I guess it doesn't have to be zwave as long as I can control with Hubitat. I have dimmable hex lights that this will be used with in my garage.
Is a single light 450w or is that combined across multiple lights?
Could maybe do some dimmer modules at each fixture and then control them from a switch on the wall that is not wired to the load. Not ideal but might be only way.
There will be two separate groups of lights, one over my one car area and a larger set over my 2 car area but they are all controlled from the same switch. Each light bar snaps together to create the Hexagons as one big fixture. I have a 5 Hex and 18 Hex pack.
For the dimmer modules, could you give me a manufacture/model number that I could look up? Want to see what LED wattage they can handle. I could potentially break them up into smaller groups.
Or might just have to use less Hexagons, Mainly need the 2 car side to dim, so may just plug the 1 car side into a smart outlet so its just on/off. But wanted to see if there were any other options out there.
The manufacturer shows a 300W LED dimmer can handle up to 11 hexagons and a 450w LED dimmer can handle up to 18 hexagons.
Thanks and appreciate the help.
Oh you don't even have the lights yet. I am surprised they do not have a 0-10v dimming option available. I would look for 0-10v lighting.
If you can get a 0-10v light this module would work:
Zooz 700 Series Z-Wave Plus Long Range 0-10 V Dimmer ZEN54 LR
There is this Qubino mini dimmer but it says it only does 200Watts: Mini Dimmer – Qubino
I think there might be some no-name Zigbee ones on Ali Express

ok thanks. I do have the lights just haven't installed them yet. But I will check those items out. Thanks again.
Legrand has a 450W dimmer. It's part of their Netatmo system, which is Zigbee based. It's not on the Hubitat compatibility list. Perhaps @mike.maxwell would be willing to add it if he had a device, I don't know if the dimmer is fully Zigbee compliant. There are a couple Legrand plugs on the compatible list.

You got me curious...
If by Dimmable Hex you mean these lights, read the details carefully, they say not to use a smart switch and it appears they have built-in 3 phase switched dimming.

- Are the lights dimmable?
No, our lights are not dimmable nor able to be placed on a dimmer switch.

@gatewoodgreen They are like those lights but the ones I have are actually dimmable from 10% to 100% and to be used with a dimmer. I will double check and see if it says anything about not using smart dimmers. If so I guess that solves my problem lol.
I was going to post a link to the lights I have but it says I cant post links. Is that because I don't have many posts yet?
Yes, to prevent spam from bot users but I think you can bypass it same as the image restriction:

Thanks that worked!
These are the lights I have.
These are a 450W LED "equivalent" intended to connect to a standard 15A outlet or wired to a dimmer switch. One of the reviews suggest that a Lutron Maestro dimmer is recommended in the instructions. Any quality z-wave or ZigBee LED compatible dimmer should work.
Did you see the suggested dimmers in the chart in the images? They only recommend the Maestro for the 5 hex kit.
But you could have a point, that 450w could be equivalent to incandescent and not actual watts. With how many lumens those are putting out I would not be surprised it’s actual draw. Need to check the specs in more detail.
EDIT: According to google you get about 75-110 lumens per watt for LED lights, so at that rate 450w would only give you 49,500 lumens. These lights are claiming to be 79200 which is probably exaggerated (and its also not that easy to measure precisely). I would not doubt that they could possibly draw up to 450w.
Found another source and it does scale up the higher you go, which I suspected:
Lumen to Watt Comparison - Energy vs Brightness
At 14,000 lumens you can get around 140 lumens/watt. So again, 79200 lumens at ~175 lumens/watt seems about right, if not maybe exaggerated a little bit.

FWIW, for comparison, searching for a 450w equivalent LED light comes up with about a 55 watt device. The specs for this light are seriously lacking.
Yes but a 55w led could never put out 79000 lumens. This is a seriously bright light. A normal led bulb ranges from 800-1200 lumens, so you are talking about the equivalent light output of 80 standard LED bulbs.

OP- did you figure out a solution? Your scenario is so similar to mine, I had to check that I didn't previously register with a weird username. I have the exact same hex segments as you linked (down to the manufacturer), but am using 66 segments in 3 groups in my garage.
I did not read the specs as carefully as you did, and I was using an UltraPro 700 Z-Wave dimmer. I was only looking at the 15A capacity, and missed the specific LED dimming capacity at 150W. I only recently noticed this was causing an alarming buzzing at the switch and my electrical panel when in use, and have swapped for a toggle until I find an alternative.
They rate the 5-hex, 25 segment kit at 250W, which (check my math) would mean .083A per segment? But then in their listing, they recommend a 450W dimmer for between 51 and 70 segments. If their power ratings were correct, I believe my 66 segments that would come out to 657W.
This new switch may work, but it depends upon the accuracy of the specs of manufacturer of your lights.
Maximum Loads
- 600W LED
- 1800W Incandescent
- 15 A Resistive / Tungsten / Incandescent
- 10 A Inductive Ballast / Electronic Ballast / LED
- 1 HP at 120 VAC Motor / 3 HP at 240 VAC Motor
Excellent, thanks! I have a Kill-a-watt knockoff on the way this weekend, I'll get an actual read on the draw and go from there. That dimmer definitely gets me a lot closer. Worst case, I might move one segment of lights to a switched wall outlet to reduce the load on the switch.
Just note that the ZEN75 is a SWITCH not a DIMMER.
Might not matter, but as DIMMER was in the post title, I thought I would mention it.

Yeah, appreciate the distinction. I might go just a straight switch if there's no other option, but definitely seeking out a dimmer if one exists.

@SuicidalSmurf haven’t found a dimmer switch to support the load as the manufacturer recommends. Right now I just have one side of my garage hooked up to an ultra pro zwave dimmer 500 series which handles 300w LED. Currently the amount of hexagons I have connected is within the specs for a 300w dimmer and works good. I haven’t put up the hex’s on the other side of the garage yet. Hoping a new dimmer switch will come out that will support a higher led load. If you end up finding one post it here. Thanks!
