Yep, this info has been out there for a while. Despite this My city has converted a significant portion of street lights to these hideous blue/white Leds. They really are unpleasant. Every now and then i find myself in areas where they still have the old hps fixtures, and i cant help but miss that that orange reddish glow. Something almost kind of romantic about that spectrum at night, lol.
From poular mechanics mag from few years back. They test the spectrum from led , incandescent, and cfl. You can google it.
These are couple cfls.

I know exactly what you mean! I always I loved the warmth it gives off.
It creates a somehow homely feeling like the warm white we use at home. If you like it try Blux Vero decor in 2500°k for your living room. I'm using decor series, 2700°k/CRI97 for my living room(Vero10) and I really like it. Digikey has vero10 and 13 in stock the last time I ordered them.
I was hoping for confirmation on a driver I ordered as I likely have a few hours before it ships and will change it if I screwed up...anyways this the info

run on driver below in series of that is best

if it is not correct maybe someone can chime in before it ships.
these will be run with good heat sinks in series I understand would be best.
please feel free to post if you can help me confirm my math
I can't open the digikey link because they block my vpn server but if its a double row f- or H-influx strip (or a single row 4 footer) and has more like 42v but less like 48v then you have the right driver. Simply connect the strips in parallel to still have the same voltage and the driver current is divided evenly by the number of strips connected.
Ah, I remember now! It's q-series, 43,5v at 450mA. An HLG-240H-48A has around 5,5A so with 10 strips each strip gets ~550mA. At this drive current a q-strip maybe needs 44v so multiplied by 5,5A you should have at least 242w net and 255w at the wall, maybe 260.
So, yeah that driver works! There is also no need to change the driver voltage. Better use the current regulator for dimming its far more exactly.
You could use a multimeter to set the driver voltage limit to 45v and add some kind of extra protection. But to reach that voltage at least 5 of the strips have to fail and thats very unlikely.
You could also use the HLG-240H-48B modell. It has no built-in regulators but a set of dimmer wires. You can use a cheap B100k potentiometer from e3ay or the rapidled 6$ dimmer, which is the better solution IMO. Rapidled has maybe a better price for the HLG-drivers too. And with 10 q-strips you are still above 50 bucks so still free shipping/no extra fees.
Believe me you will love the dimming feature because it al!ows you to inspect the plants without switching the light off. The colors will look much brighter than they are under intense LED light. So its really a useful feature!
Dimming also allows you to suspend the light always with the same distance and adjust only the brightness level. With an HLG-240H-48A you are limited to 50-100% dimming and you always need a small screwdriver to adjust brightness.
No "damned, where is this shitty screwdriver again" anymore with B-type drivers. Much more confortable.
