best light for 2x4 ?

best spectrum for flowering only? 3500k? mix of 3000k/5000k , only 5000k
basicly im looking at the migro light 3500k only , the chilled growcraft x330 with a mix 3k/5k or the growerchoice ROI 200 , also the raging kale but it advertise for veg and since i dont have the money for a alpha scynce or the scynce raging kush ...taught?
only for flower

3500 for flower.

3500k is a great all around spectrum and works great for flower and veg. 3000k would be a more flower centric spectrum. However if you may wanna go 3500k anyway, the extra bit of blue helps with transpiration which can be a problem with a led grow when you dont have good control of climate, especially if its hard to hit +81F at full power flower intensity. It should prove a bit easier to grow with.
Mixed 3000k/5000k: if half and half its the same as 4000k, not one bit of difference. These lights with mixed spectrums like that get marketed like "3000k for flower and 5000K for vegg" but this is really a load of shit, its just the same as 4000k which would be standard for vegg. I think companies do this in order to be able to get a large order of diodes in and then they can mix spectrums in Spain order to get anything between 3000k to 5000k; if they went with straight 4000k it would tie them to this spectrum with no possibility to vary.

yeah i would go lower then 3500k but i dont know any light that as it other then those more expensive light that you can control the spectrum like those scynce led but i dont have the money for that , any one know some that as just 3000k diode or lower ? ideally id take like 80% 3000k or even lower and with 10 % 4000k and 10% 5000k not counting the far and deep red diode,i found there a lot more option for the 4x4 and 5x5 compare to 4x2 for high performance light

Not a huge market for 2x4 stuff unfortunately. At least there is not much demand for hi end fancy stuff in that size.

Timber will sell a 3000k option of their lights.

I have a cypress 4. But it looks like they only do a cypress 3 now.

Personally I'd get the ChilLed. I've been wanting a couple X3's. You should get 5% more off though this link if you decide to go with ChilLed.

ChilLed has a separate veg model and flower model. You choose the spectrum at checkout.

i think you are giving 90% of the lighting companys too much credit, i think the reason they mix the diodes is because they honestly think they get the best of both worlds, veg + flower from a single light.

im convinced that the majority of lighting companys are ran by morons who are just playing copy cat...

You might be right, but even chilled do it; i dont expect Vasilij (or whats his name) and and GM5 to believe shit like that. It might also be that 4000k carries a premium price from Samsung. In any case mixing spectrums like that is just gives you the same as the average.

Its a bit unclear cause when you look up specs it says 140 leds each of 3000k and 5000k and doesnt indicate if its their flower or veg model. But mixxing spectrums would be for this exact purpose: you order both and can make any spectrum from warm to cold.
Also a bit surprised on chilleds diode count, 740 whites+ 45 reds for 330w light is not that great. Its less than hlg320 fixture. But hey they got that ultra version aswell. But still expected a bit more for the price premium.

Edit: bad counting, its 840 diodes.

i ask them and they told me the mix was 50/50 even for the flower version , i think the veg version got some deep red replace by some straight blue diode , it as to be with the cri ,if its 80 cri its a big difference compare to 90 cri ,chilled is probly 90 cri .

The engy that designed the mounting hardware for this timber i bought did not graduate first grade and does not know how triangles work.

id consider hlg but they dont have bars style led and i find the ppfd not even , i find it comparable to spiderfarmer , they just space their board a lil more in between to give a better coverage but thats it i believe

HLG started quantum boards. That's actually a trademark name. No one else is allowed to call theirs quantum boards. So basically everybody who makes boards is copying HLG. I love all mine. But my next light is gonna be a ChilLed Growcraft.

If you did decide on HLG make sure to use the RIU10 code.

so glad someone else is pointing this out. To be clear white phosphor led's, blend, so CCT is the average of what ever is used, Mono chromatics do not blend but have the capacity to shift CCT and CRI of white blends
cheers

hmmm i doubt mau5 had any real say at chilLed, and i doubt vasaline has grown anything other than his hair...

still it wouldnt supprise me if chilLed's use of 50/50 3000k + 5000k in their standard growcraft was just because when it was designed (a few years ago now) they honestly didnt know any better...

their new growcraft ultra uses all 5000k now, but i recon they just wanted to get over the 3umole/j barrier for advertising ect, without using 10,000+ diodes so they kind of had no choice...

im not bashing chilLed i like them, their gear is top quality and some of the stuff they have coming looks cool.

4000k (or this half an half mix) + decent amount of reds makes a lower K, usually about 3500k. Which makes sense, its fairly standard high efficiency spectrum. But adding extra 450nm blues to 4000k?? It doesnt do anything to your light which a straight 5000k spectrum dont. No sense. Maybe its another blue, 440/460/475? Who knows, no info on the web.
90cri? Yes maybe the resulting spectrum but the white diodes are 80cri. 80cri + red 660 boost gives something close to 90cri but its not the same as a white midpower 90cri diodes: they have a slightly different spectrum.

Which ones are you looking at? Comercial grade? Quite spendy$$$. The DIY version? Double check with chilled what warranty they come with, i believe its close to nothing from what i heard.
Maybe have a look at the HLG200 diablo aswell. You could hve 2 of those, dimmed down a bit, for about the same price as one chilled 330 diy, you could do 3 if youre looking at commercial grade.
It has superior diode count (by a lot! 666 diode for 200, versus 4and newer diodes (lm301h evo with 435nm photon pump), higher efficiency and better spectrum: their blue bump is wider and covers chloropeak at 440 much better. Your likely to be avle to run your 4x2 with less watts. RN it feels like a crazy good deal, 4x 200w diablos cost less than the 650r which is the same but with less watts and spread, but with about 150w less wattage. I dont think they will keep it like that for long since its going to hurt their bottom line. Also iirc, those hlg200 comes with standard warranty and not diy warranty.

yeah the chilled as 15 deep red per bar X3 so 45 ,the hlg 200 as 18 so if i run two id have less deep red but more white ,chilled is 140 of each 3k/5k per bar so x3 and hlg 648 per board so 1296 , hlg look like they have a mix of 3k/5k too but im not sure ,i havent ask them but good to know ill check out the 200hlg thamk you
