Yes, the prices I have listed are WITH OUT the 25% discount available now. None of our systems currently come with dimmable switches. However, for a bump in price we can have them put in if it was something you really need/want. The drivers needed for the dimming feature are larger and we would require a different casing all together to fit them into the unit. Throw in the cost for the switches, new drivers, new aluminum cases, & the lazer engraving, your looking at about 48-50$ added on per panel just for the dimming feature.
Go ahead and send us an email and speak with Victor about your current situation and what it is your interested in product wise. I am sure he will be more than happy to help you out and answer any further questions you may have in regards to the modifications your inquiring about with the lights.
Hope all is well with you and yours! Happy growing!
Thanks man!
