The Bridgelux Vesta LED strip are a good inexpensive introduction into Variable tuning, adjusting the Spectral Wavelength Percentage distribution...

IMO, using 3000K to 4000K LED of the same CRI almost defeats the purpose of tuning which is to change the "Spectral Wavelength Percentage Distribution". Depending on the application you should use a High CRI "Base" (High % Red) and add Blue, Red or an High CCT / Low CRI "Supplements",e.g.;

2700K : 5000K @ 3:1 Base Ratio;
2700K 90 CRI (75%) : 5000K 80 CRI (25%) Base = 3275K
2700K 90 CRI (25%) : 5000K 80 CRI (25%) Veg = 3850K

2700K : 5700K @ 3:1 Base Ratio;
2700K 90 CRI (75%) : 5700K 80 CRI (25%) Base = 3450K
2700K 90 CRI (25%) : 5700K 80 CRI (25%) Veg = 4200K

2700K : 6500K @ 3:1 Base Ratio;
2700K 90 CRI (75%) : 6500K 80 CRI (25%) Base = 3650K
2700K 90 CRI (25%) : 6500K 80 CRI (25%) Veg = 4600K

3000K : 5000K @ 3:1 Base Ratio;
3000K 90 CRI (75%) : 5000K 80 CRI (25%) Base = 3500K
3000K 90 CRI (25%) : 5000K 80 CRI (25%) Veg = 4000K

Good Luck.

BTW, Full Disclosure, I'm also a noob currently making a PC Red 560mm supplemental strip ... download/file.php?id=4509&mode=view

Im not trying to sell you a PC red Buddies strip but just wanted to explain that a strip of Buddies has 160 leds. There are 8 chips in each PC red Buddy.
This is why the efficiency is higher on the Buddies than it will be on the lumileds PC red.

The chips used in Buddies are slightly more efficient than the ones lumileds do also. Im just not sure its worth the effort you are going through when there is already a product available that is better than what you plan to produce and price isn't too bad either.

You math is also based on the lumileds data sheet which will be about 8% lower in real life tests. There is a big difference between data sheets and proper testing.

I still have the PC RED Buddies bookmarked, but had already been looking at the SunPlus 2835 LEDs. The cost for three (3) prototype strips is just under $15.00 (US), all parts are already on hand, just need an hour or two of "quiet time" for assembly.

When used as a Supplement at 10% (25 Watts) of total Watts the math is; there is only a 5 Watt difference between the efficiency of PC Red Buddies @ PPE 2.0 (umol/J) and SunPlus Purple 2.5% @ PPE 1.65 (umol/J) . Also the PC Red Top Light Supplement (600 - 750 nm "wideband") would be unnecessary if the "Base" Light was a good 90 CRI spectrum...

[TEKNIK]

You are right, a good CRI90 means there is no need for PC red. This is why you will often see me suggest to people to go for 2700K CRI90

PC red does have its role but alot of the time things can be changed so it is not needed especially for top lights.

Under canopy and side lighting is very different and PC red is better in many cases for that purpose.

I agree with and used several of your recommendations, thanks. Had already planned on trialing the Lumileds due to the efficacy, low cost and availability of both the SunPlus Purple LEDs and Samsung V562B, 560mm, 2835 CEM-3 Copper Double Layer PCBs, it takes less than 5 minutes to set up and remove the thirty two (32) 4000K LEDs from each strip (Flux plus 400° Hot Air, "Trial and Error", very fast and clean). Still looking for some 420 - 430 nm Violet LEDs, if available in 2835 they could possibly be added to these strips...

They look great! are you assembling them yourself or having it done by someone?

Thanks, DIYing them myself, IMO they actually look very professional , even compared side by side with the Samsung and Bridgelux LED Strips...
Much easier that I thought they would be, but have lots of soldering and some welding experience. An inexpensive Hot Air Rework Station is the Key to the whole project, 5 minutes to remove the White LEDs from each PCB (400°C Hot Air with Flux Paste), 15 minutes to place Solder Paste and LEDs then 5 minutes Reflow with Hot Air (300°C Hot Air)...

Wow! So you have done the whole process yourself? I've got lots of welding and a little soldering experience that's about it haha.
That's so great I love the DIY nothing like doing it yoursef and of course learning something new. I just want to build some lights for myself and my mates to what we want.

There is nothing wrong with using existing LED Strips in combinations, preferably with a 90 CRI "Base Light"...

I totally agree there is nothing wrong with it at all, just not the direction I wish go
How have you learnt so much so fast? Haha it's impressive your only a noob I appreciate the help!
