I've got a DIY LED question and this seems like the place to ask it. I hope this doesnt seem like hijacking.
I want a blue LED bar but I dont want to pay the (IMO 2- to 4-fold overpriced) Orphek bar price.
https://www.saltwateraquarium.com/48-blue-plus-light-bar-led-or2-120-orphek/
eBay has similar items for about $80-$90, but the 48" one is always out of stock. (They are in stock at Aliexpress, so I can always buy there instead)

That is still overpriced relative to black boxes (fewer components but the same price), so I know we can do better. My questions for the DIY community:
1. Has anyone made a bar-style DIY LED? I'd love to see details if so.
2. How much can we beat the $80-$90 price by going DIY?
Specifically, I want a 48" array of 3W blue/violet LEDs. No special dimming or controls required. I would prefer a design with a fan but if it's worked for others without a fan I'd be open to trying that too.
Thanks!

Okay, so what about purple? Well, if you mix red and blue light you excite red and blue cones and you experience purple. There’s no doubting that. But unlike yellow, if you look for light whose frequency is half way between red and blue to do the same job you are slap bang in the middle of the greens, and not surprisingly what you see is green, not purple at all.
So the only way we can experience purple is by seeing red and blue simultaneously. There is no such thing as purple light. No single frequency of electromagnetic radiation can give you that purple feeling. The experience of purple is an anomaly of the way we see colour and as such I would suggest that it is the most intimate and personal of colours, created purely in the depths of our perceptual system. This is not true of any other colour but regal, sensual purple.
That also, surely, gives purple a unique place in the artist’s palette. A purple pigment is not reflecting purple light into our eyes but red and blue without green. Purple is a kind of ungreen.
Just for fun...

So I added a Luxeon rebel 3-up cyan and removed the 3 hyper violets I added and I think this new look will do. Still has a hint of purple-ish(indigo?) but more like a MH.
I really need to get my hands on a par meter, or just breakdown and buy one to see if I'm going to stick with the DIY vs 2x viparspectras.

I'm reconfiguring my 6" MakersLED sink for reef use, and will be posting some pics soon. Life got funky for a while so most of my hobbies went on hold but I'm back
OH, by the way- Steve's LEDs carries cyan again!
Looks like I need to order a few 3-ups with them onboard for some projects. violet, cool blue, and cyan 3-ups are very useful for adding to k16 and white based builds.
