Popular Grow LED Modification

[Moronta12]

Hi Guys.... I have a question for the LED BARS GURUS.
I just bought 2 Popular Grow LED Bars to complement the 2 Radions XR15s that I have over my tank right now. I ordered the full spectrum because I don't like to see my tank super super blue. But It turns out that this full spectrum is too white. What combination of LEDS do you recommend to match the AB+ of my Radion lights.

Thanks in advance.

Here is a Picture of what I got.

First one can't decide on what to change without knowing what is there.
Second these models are waterproofed (???) unlike the old ones.
No idea how easy/hard it is to disassemble and how easy/hard it is to re-waterproof it..
Third what are the type of LEDs? If and it will be hard to replace. If those, as I like to call them egg type ( white LEDs have yellow centers ) then usually no problems.
Lastly, par losses which I will get to below


Now for a crazy yet relatively sound idea IF you can handle output losses.
First the bad.. What you will be "adding" is just the 450-ish royal blue part of the white.
Adding is a bad term since you will just filter out much of the "white" part of the led.

Rough calculation is the range of 500 and below is about 30% of the diodes output.
Soo if one is not using them for the major par provider a blue Roscolux filter over the whites is an option.

Sooo roughly if you have 50% whites and lose 70% of 50% you lose 35%...or something like that.

There will be some losses but can be minimized
.

.

Probably not what you had in mind though.
Btw estimates were based on 10000K white LEDs. Higher k have higher % blue,lower less.

Just noticed the above filter was a glass based. Should have a gel equivalent ..

Great!!!
Yes so, they are easy to take apart and put back, I just watch a video.
Original Diodes are as you say 3W egg type. PAR isn't a big deal for me, I have 2 Radios over the tank providing good par, my Main concern is try to reduce the shadows (and also match those 7 hours of full AB+ day light that I got from the Radions.

Now, if I understood well your recommendation. I will start replacing 70% of those white diodes for 450nm, Right?

If it is like that, it sounds pretty simple. Thanks brother @oreo54 for the advice.

Err.. not quite.
The filters were to eliminate any need for changing any diodes.
But obvious not what you would prefer.

Sooo brings us back to exactly how you want to modify the orig.
For that the best approach is to know what diodes are in it now. Then adjust accordingly.

Your above plan is fine btw but it has no specific spectrum you are matching.
Again would need to know what is there now.
I see it has violets, 9-ish royal blue, some regular blue and about 12 high k white.

Actually adding like 8 440-450 might just do it

Just a small follow up. I found the plastic equivalent has much lower transmission in the blue than the quoted glass filter above
.Instead of like 90's in the blue range it is more in the 50% transmission making it even less practical
Checking with Rosco out of curiosity.
