Giesemann verrve

Anyone using this light? Any thoughts on how I have them mounted? Should they be end to end?It's not easy to fine tune with the app should I use reef 1 or 2?

Lets get you some help

I’m still curious how people run the lighting schedule with this light? I’ve been running it on preset reef 1 for over a year now. I feel lighting is the one parameter I can keep constant but maybe this is too much light hours for my tank? I’ve been looking at the 4-8-4-8 light cycle but I would like to here more thoughts before I change too much.

So I’ve had both lights in for repair twice now for LED’s burning out. CoralVue has been nice enough to fix them under warranty. I just got the master back today and the face plate is bent out and the toggle switch isn’t working. I’m sure they will fix it again but I want to know if anyone else is having problems with this light or is it just me?

Anyone have recommendations for new lights if I can’t get this working? 120 gallon fat boy with a canopy just for looks? I definitely like the full spectrum and the white looking lights and I like the idea of two separate lights so one can be sent in for repair.

Mixed reef but I want more Acropora.

I have two brand new mounts for this lights. I bought them to mount a couple of mitras, but went a different way. I'll let them go cheap if your interested. I don't think they make them anymore.

I’m happy with the way I have them mounted just not happy having to send them in for repair so often and then getting them back broken. One time they repaired the slave and didn’t put all of the mounting nuts inside the light. I’ve never got the storm features to work properly. Just not happy with the lights in general. They look nice and grow corals ok but to many problems.

Ok. Figured I'd ask.

I’ve been very pleased with my ReeFi lights. https://www.reefi-lab.com/product/reefi-led-duo-extreme/

The Phillips CoralCare looks promising but it’s not coming out until August or so. ReefBreeders are a good choice as well.

That extreme looks nice how long have you had it?

I think I installed them around the beginning of February. Haven’t had any issues and @danlu_gt does a great job supporting his product. If you have any questions about them, I’m sure he’d be happy to answer.

Interesting 'New' LED Light

I just received two ReeFi LED lights for testing purposes. This company has been around for a while, but it is new to me, and I'm impressed with the thoughtful design. There are 72 LEDs in the array including cool white, warm white, amber, lime, blue, royal blue, violet, 420nm and 400nm, each on...

ReeFi Duo Extreme LED unboxing and first impressions

Last weekend I hosted my local aquarium club (PNWMAS) monthly meeting at my house to show off my Reefer XL 425 and all my Apex automation. It was a great turnout with about 30 people, and I also spent some quality time grilling up chicken, burgers, and bratwurst on my BBQ for the crowd. Fun...

So I took some par readings and found under the slave I got 350 at the corals, under the master that just got repaired 190 at the corals. I can’t get ether light to respond to the toggle switch so I can’t get them to work together and I can’t adjust the slave at all. No response from CoralVue yet.

Check to see if master, in this case gets hot, or, warmer/hotter than other unit. Should this be the case, likely fan out, then LEDs won't max out and run lower percentage than set. This happened to me, I am back to good ole ATI t5.

Badilac · May 28, 2020

I have come to the conclusion those lights are trash! I had a pair that I could never get to work right.

slave would continually disconnect from the master. Got parts from Giesemann direct after continual run around from Coralvue had to install the parts myself.

Slave was 20% brighter than master and over heated 10-20 times a day because it was drawing 20% more power (fan worked but couldn't keep up and room was kept at 69-70f at all times). Giesemann would only repair it if I paid shipping to and from germany even though it was under warranty.

also the slave was super noisy unless it was running 100% if you dimmed the LED's it hummed like hell.

ABSOULTE TRASH! glad I got rid of them. I now run Reefbreeders and Im happy.

Both lights feel the same temp and fans are running about same. I did check the par within the first 5 minutes of running last night with the live controller all channels at 100% and thought it just might need to warm up so I let it run the schedule today and checked again same results.

Wow I thought I was having bad luck sounds like you had it worse.

Oh yeah and I wish you luck. I also had display issues.

I’m definitely looking at new lights hope I can keep the Giesemmans working till I can save up for some nice lights.

Perry · May 28, 2020

I had display issues, back light. Slave had burned out 4 diodes, and fan went out, so I got similar par results. All in all, when they worked, pretty decent light, but ZERO support in US. Coralvue shouldn't sell something they cannot properly support, bottom line! I used ti be in the industry and even know some of those guys, they wanted nothing to do with me. Also, bought Geissemann Stellar and couldn't get support on it, was actually going to use my one good verve in between, but brackets nowhere available for shortening unit, as my tank is 20". Light unit 22", with 10" gap between t5 banks. Shipped it back and replaced with ATI. I personally refuse to buy any products offered by Coralvue, very rude, and wanted nothing to do with me!
My rant, lol

You may have additional warranty or purchase protection if you purchased with a credit card. Everyone's terms are different, but here's the gist of it https://thepointsguy.com/guide/best-cards-for-extended-warranty/

If the lights don't work and you are not getting resolution from the manufacturer or reseller, it may be something to look into.
