I've worked around 3 yrs to develop the darker blue in the DBVs. Yes, they are a darker blue, however they do throw a lighter blue maybe 5% of the time or so. The DBV lights are still darker than the BVs I've had though. DBV are 4.95 ea.
I usually mail on Sat morn to have minimum amount of time on trucks and rush the package priority through the system for best live arrival.
If you need more info, or want to order- feel free to pm me for more privacy.
