Viparspectra 165watt, Anyone using these?

Yeah, controlled with ReefPi.

I thought you might have done something like that. I not fussed about controlling mine just want the colour that I like really. Also beneficial to the corals

I may be a little late with my information but here goes.
I found a web site that tested par on several models and posted their findings.
They said at 24 inches depth directly under the unit at full intensity they read 350 par at 6 inches it was close to 1000. this was done with the unit 8 inches above the water. both channels on full. I hope this is helpful.

I've changed mine yet again, this is my new layout.

I'm not sure what settings I'm going to run it at yet. Currently its 45 blue 30 white.

Hello all, does any one have suggestions for heavy duty/ceiling hooks, anchors toggle bolts to use to hang the 300w light on ceiling drywall? I believe the weight is 20-15 lbs. I have a local ACE- HD and Lowe’s by me.
thanks

It's always best to find joists or studs though.

I just hung two of the 300 watt versions using these toggle anchors with hooks that have a matching thread size.. I agree that going into a joist is the best option but in my case they didn't line up so I would've had to mount a board to my ceiling. I watched videos showing these hold around 100 lbs from a ceiling so I just used them. They easily feel secure enough to hang the lights from.

Got a link to these? How long have you had them hung for? Any issues?

I bought them at lowes along with 1/4 20 eye bolts to thread into them. I have only had them hung for about a week, so I clearly can't attest to their longevity, but they seem plenty secure to hang the lights on.
I was about to mount a rail to my ceiling to hang my lights from but I watched multiple YouTube videos testing the load that these anchors can hold and decided the lights weren't even close to maxing out these toggles.

I agree that screwing directly into a joist is by far the best way to go, but I'd guess it's fairly rare that the joists line up with where they would need to be. Which only leaves the options of mounting a wood/metal bar to the ceiling to attach to (which in my case my wife didn't approve of) or using drywall anchors.

First, is the tank next to a wall?
Then I'd switch to wall brackets.


List 20# PER hook..

I think about 3 toggles will work fine.
People SAY drywall is stronger than one assumes but .. ??
