Author here, happy to answer any questions about the journey!

So just to confirm, the actual cause for the controls not working is still unknown to the reader but the reason the measurements didn't make sense was swapped labels?

>>sberen+(OP)
Do you have any recommendations for FCC/CE testing providers?

>>Neywin+dm
The controls weren't working because we had wired them up according to the labels which were wrong (which is also why the measurements didn't make sense to us).

>>sberen+kK
Ah. A lesson from somebody who's built hardware that I'm sure you've now learned: make sure connectors can't plug into eachother unless they're supposed to. Even if they're different connectors, different keying, whatever, sometimes they can still be forced together.

>>sberen+(OP)
What was your marketing strategy once you had the $10 deposit landing page setup?

>>Neywin+8L
I built a lot of Ikea last month. And I was just marveling how cleverly designed everything was so that it was quite difficult to put two wrong pieces together. Mostly, the only warnings in the manuals were to rotate a piece correctly.

>>sberen+(OP)
I definitely feel your pain. I own a company that makes custom process controls for industrial and commercial clients, and while we work from a large library of hardware and software designs from past jobs, every job has a lot of the same "start from the beginning" feel as what you went through. Especially, the one thing you didn't check is always the thing that is somehow screwed up, and the sleepless nights wondering halfway into the project if you're in deep trouble.

Got a discount code for the HN family? ;-)

Congrats on shipping. I'm living in the EU working California hours (4pm-1am) and will definitely be buying one.

>>sberen+(OP)
Just curious about the frequency of the diodes and do they pulse simultaneously? Quite often I can perceive flicker in moving objects indoors.

>>sberen+(OP)
Hello, nice write up. I'm curious about your deal with the factory and downstream suppliers.. did all these iterations and fixes cost more every time? Or it was a fixed contract? How does that all work

>>srtw+yK7
We use constant current reduction dimming so there's zero flicker!

>>Neywin+8L
This is good advice for robust design, but I swear, 9 times out of 10, you will be the one who keys it the wrong way during CAD layout.

>>sberen+KK7
That’s great to hear and a big plus, but I’m actually curious about the undimmed full brightness refresh rate of the LEDs.

>>srtw+mM7
If it’s constant current the “refresh rate” is infinite, or zero depending how you look at it.

>>dickfi+iJ7
Just made one - use HN100: https://getbrighter.com/discount/HN100 :)

>>drum55+XM7
Didn’t realize how they actually function, looks like I need some new lights.

>>sberen+(OP)
Being 6'5" myself, I am worried I'd be blinded by the lamp when I stand up: to avoid adding a base under (an already bulky) base, is there a way to separate the lamp itself and have it wall/ceiling mounted (still pointing upwards)?

>>sberen+(OP)
How did you figure out how to price your product?

>>necove+IW7
Because the lamp is 6'3" it's only below eye level for people who are 6'7-8.

We had another 6'5" customer who was worried about the height but they said it was totally fine even with shoes on.

>>Neywin+8L
I've seen datacenter techs successfully force an SFP optic in an RJ45 port. So yeah, the shape needs to be very different.

>>sberen+(OP)
Which NRTL did you end up using for certifications? Can you say more about that process?

>>sberen+KK7
Isn’t that less efficient in power and can have different color?

>>fxtent+Eu
I'm really curious how they handled certification of a design that was changing apaprently up to the minute it was delivered...

>>rxt_ia+AZ8
My first guess was that they used an external brick for the power supply with a relatively low output voltage--that would eliminate a lot of the CE test load. However, a cursory glance at the product photos suggests the power supply sits within the base of the lamp. Maybe the product developer can shed some more light on this. ;-)

>>XRG+la9
That would certainly make certification easier, but as I suspect you understand, wouldnt achieve it alone.

Even if every component was CE qualified, the combination would have to pass its own testing, plus there are a lot more to the standards than just not electrocuting you immediately upon contact.

I can't see any of the energy efficiency labelling that would be required in the UK or EU for example...

>>sberen+7N7
Is this coupon still valid? I don't see any price difference...

>>yoavm+xC9
It works but only when you put it in the basket ;)

>>fxtent+Eu
FWIW I've had good luck with Intertek https://www.intertek.com/ for most testing and certification processes across a variety of products.

>>rxt_ia+zi9
1. there's no official mention of any CE / FCC certification

2. I asked shortly after the author offered to answer questions, but there was no response

I'm starting to wonder if this project maybe just shipped without CE / FCC certification because they didn't know it would be required.

>>sberen+MY7
Thanks for confirmation, but anatomies of people, especially at the p5/p95 extremes, can be widely different: maybe I've got a very small head with a short forehead :)

So in a sense, I'd still like an option to mount it differently and more out of the way before splurging €1.2k + ~30% customs/VAT on something like this.

This even prompted me to check out comparable video fill lights on Aliexpress, and they also run around $1k (some at $500 with possibly a few gotchas about actual light output) for comparable luminosity/wattage, so your price is actually not too shabby.

>>fxtent+DU9
In the absence of any evidence to the contrary it certainly seems likely.

Pretty concerning for such a high power device.

>>sberen+(OP)
Did you find your CM through your own network? Tradeshows? Cold calling?

>>shadow+gD8
It has to be an SMPSU in constant current mode, not a linear power supply. I'm sure it does still affect the colour, though.

>>sberen+KK7
Have you measured the ripple on the SMPSU output when dimming?
