Anyone know off hand what size screws the 132's take for mounting?

I was told that HLG make the quantum boards in China and the do not have their own pick and place and reflow oven to make these in the USA, is this true? I thought they were a made in the USA product and they conducted extensive research with different spectrums and chips to come up with the configurations they sell.

I don't see anything really off base in what you're saying but I'll just add this: Breakers are generally rated at 80% of stated amperage, so a 15A breaker can only safely handle 12A continuous loads...stupid yes, but also true. Upsizing your wiring is a great way to future proof your installation but also running an 'edison 3 wire' style circuit using 2 phases of 'hot' (like an oven receptacle) will give you the option to run 240V and drop your amperage.

They make some in house and some come directly from samsung. They have videos somewhere showing the fancy new machine so I think you can rest assured that they are either honest about it or great magicians. Either way, they are making a strong name for themselves for quality and backing up their products.

Did the person who told you that, recently have part of their brain surgically removed?

So what you are saying is HLG boards are not made in China? Everything is done in house in the USA? It was just something I was told and wanted to ask if it was true.

They have their own pick and place and reflow oven etc in their factory in USA (Tennessee? hillbilly redneck country?)
Some of the early QB`s may have been contracted out & made in China, where they learnt how to blatantly copy them & sell them as their own idea (arsewipes)

OK thank you for clearing that up, so all boards HLG produce are made in the USA. I am not sure why the do not promote themselves as a made in USA product it seems strange. Anyway thank you, I am not sure why one of the guys from HLG didn't answer the question but thanks.

Nice to finally meet you Stephen. Looks like you guys are still setting up and very busy. Stephen did you read about what I am doing regarding IES files, I want HLG to be part of what I am doing, I believe it's the next step for DIY

I haven't seen but do understand. Honestly we have been waiting on the upcoming near field testing to be finalized. It uses a Gantry and generates a way more accurate depiction of light spread vs far field goniometer measurements. As you already know a goniometer treats each light as a point source which is ok in far field but is inaccurate at distances closer than under 3X the largest side of the fixture/light source being measured. These pictures are from last year. We have been up and running since DEC . I'll be sure to post more pics here that aren't in my phone. We have videos and pictures on our Instagram as well .

I find that my goniometer is actually very accurate and quite good for IES files, the results are more than accurate enough for horticultural purposes. I want to get all the data together as soon as I can so people can see everything clearly before making a purchase. Please Pm me if you want to be involved as I would hate for HLG to not be on the database, it is much easier for me to do tests when the manufacturer is helping me by sending me the products to be tested.

This is the equipment I use, it's far field measurement and I measure it from 8X the largest diameter of what I am testing.

Why would that measurement even be useful in a light built to be able to be kept extremely close to the canopy? I'm not being snarky, I'm just not seeing the point of far field measurements when I'm running QBs at 18 inches or less from the tops of the of the plants for almost the entire cycle. I understand it works well with the file type you're working with, but as Stephen stated, the ability to get more accurate data about a lights performance within its intended usage parameters is ultimately far more valuable to me.

Regarding how far field measurements work it is just how the machine works and isn't really relevant to what you guys want to see, it's more of a technical thing about accuracy in a goniometer test. My machine makes it very accurate.
Reports that the machine generates is accurate and more accurate than a sphere test and separate goniometer test. The reason the IES files are going to work for you guys is because you can mount the light at 18 inches and see exactly how it will spread and the par levels at the canopy on a very easy to use free to download program before you have made a purchase. You would be very surprised how some lights spread at different heights. Basically if I do a test then it eliminates the need to use a hand held par meter as it can all be done on a computer.
