2:1 of cool whites to blue... maybe. Any addition of neutral or warm whites needs at least 3:1 or even 4:1 for 20k at 100%. The whites from EG are extremely bright. 17 out of 55 leds in my IT2040 are a mix of neutral and warm white, and at 100% it is a 10-12k look.
Bhazard451 sorry for spamming you. I didnt understand if you ment that the IT 2040 from evergrow had resistive dimming? Thank you.
