I don't think those values are too bad at all, although I don't know how to calculate PAR from multiple fixtures. It looks like the PAR meter's values are 20% shy of the combined PAR rating from BML's webstite of the two fixtures.
I haven't tested PAR for a single fixture, but I may just to see. The distance to my substrate is 21" even with the 4" mount of the fixture above the tank.

When items are made to order prepayment is pretty standard. It's a royal pain in the ass to put in the time to build/make something only to have the interested party leave you high and dry. That's just part of the territory when you buy made to order products. I understand the frustration with having to pay for an item that is mass produced only to wait a couple weeks+ for it to ship. (Thanks Amazon!) Just be glad that your wait is for a hand made product, not something that is being mass produced in a prison work camp in some third world country.

My light arrived this morning. I was pleased with how everything was packaged and such, nothing fancy but it was all nice and secure. The light is currently hanging using my old t5's set up while I build another one specifically for the mounts on the BML. Just going off the little bit I've seen so far I'm sure glad I got the dimmer, full strength would've started an algae factory. Ha! I've not got a PAR meter so I will be adjusting the light strength based off plant growth and algae for now. Once I've got the light in it's actual mount I will figure out my starting point, probably 50-75%.

What it comes down to is this, when I pay a premium for something, I expect things to go well at all stages, not just most. Had I ordered a custom fixture, that might be one thing, but I ordered a "stock" unit that the are accustomed to making. I would expect that when I order, they would be ready and the unit production would begin and take 2-3 days to complete and ship. I understand it's good quality, and that I'll likely be thrilled with the light, but I think people are getting a little too defensive about this.

I've had a conversation with Cara about a question and she was fantastic, I will likely find the light to be fantastic, this is just one piece I find to be less than satisfactory, and as my money is gone and the light hasn't shipped yet, sadly it's the only thing about the light I really have to discuss at the moment!

And yeah, Amazon is amazing. Johnson, what size tank/fixture did you get? My call to Cara was actually about a dimmer, and she said that regular series on a 75g with pressurized CO2 would be fine without a dimmer. I suspected as much, but am interested to know how you work out.

TPT says I'm an algae grower... I'd like to think of myself as one hell of a Cabomba farmer.

I got a 36", 90* XB series, it will start out about 16-18" above the water/25-27" above substrate on my 20L riparium. I went with the 36" as I've got a planted hob that I would like to add more to but it never seemed to have enough light with the old 30". I'm hoping I will be able to still run the light fairly bright as I think the rip. plants will filter it pretty well. The plan is to upgrade the tank to a 40B which will probably be more appropriate for the light at 100%.

Here's a couple shots from unpacking and how it's currently hung.

The bagged plants next to everything are a couple Crypt. affinis 'Metallic Red'.





How do you think the PAR is at 42" above substrate. LOL!!

Luckily(HA!)I was dealing with kidney stones and I had surgery a few days after I ordered mine so I spent the first week doped up & passed out on the couch. This week, while I'm still recovering, I have spent most of my time trying to catch up on everything I put off for the last month while having to take excessive amounts of pain killers! So I haven't been too stressed about the light.

Just to add to it, for those anxiously awaiting the arrival of their light, you may want to call BML and tell them to deliver without a signature. I would hate for you to not be there and have to wait another day. For some reason they want a signature for everything.

When I got the email with tracking number, once you pull up the fedex tracking you have the option to change any of your delivery preferences. I didn't look too deeply into it but I would guess that might be an option you can adjust.

Edit: Mine didn't require a signature this morning.

For reference for others I ordered on 3/10 and Cara told me today mine should ship Monday. It was being finished today. So two full weeks from order date to shipment.

I tend to agree that i do not like being charged for something before it is shipped. However it is easy to get around this. Order a product on the first billing day of your credit card not the last. Product gets delivered in two weeks but you will have it up and running two weeks before your bill arrives. You are playing with house money.

I hung my BML over my 75g. Still have it set at about 75%.

Looks like a nice light, just wish my 75g looks as nice!

I bought the mounting kit with mine, we'll see if I end up using it long once it comes in. Might have to raise it.

Front of glass say 3-6 inches from 10000k say 70 par plus 9-12 inches from 7000k say 40 par equals 110 par.
Haha, oops. Totally forgot to take account the 4" above water's surface, I did the figuring and just shared cause, well, I already did it. Of course, 4" to 6" is not penetrating through water.

So, is this your 3rd fixture? Lucky you if it is. Or did you 'borrow' one from your 125g? What is the length of your 125g?

Yes, I have 3. One on the 75 and two are on one of my 125s. My 125 is 72".

I have both setups adjusted down quite a bit. I don't need or want 120+ PAR anywhere. Hanging them spreads the light quite a bit and mostly removes the issue with LEDs being so focused.
