Much appreciated to both of you.
In direct response to Knytiri, I completely understand. I personally try not to be a huge hassle when it comes to online ordering, regardless of the source. I know it's very difficult to accommodate customers' requests so late in the production stage, which is why I made a (feeble) attempt to ensure that my order notes were received. I can also definitely see how hard you guys work to make your customers happy, you're working with such a high-end product to begin with that each component really can't be wasted over an indecisive customer.
In hindsight I should have probably specifically pointed out the portion of my notes which detailed my desire for 12w+, but there was a fine line between confirming and annoying which I really didn't want to cross.
At this point, I'm definitely more at ease and would ultimately be fine with the standard LEDs, although of course it would be hugely preferable to have exactly what I ordered, considering how much thought I put into this purchase before placing the order.
Thank you so much for contacting the production manager on my behalf, I certainly do understand where you're coming from and the lengths that you're going to both answer my queries and rectify the unfortunate miscommunication is greatly appreciated.
Have a great rest of the weekend to the both of you!
