Almost all lights I purchased in the past two years are lights with RGB aux with only handful exceptions.
I guess I am attracted to the functionality of RGB aux and the looks. RGB aux can display useful information about the light (I can take a glance and check my battery level) and it looks quite nice on the desk.
However RGB lights can consume significant amount of battery. On my D4V2, it can consume up to 8mA on high aux setting. (The power consumption depends how many R, G, B leds are lit) At this level power consumption, it is not practical to leave them on 24/7. Here are some measurements ( Emisar D4V2 and D4SV2 auxillary LED current draw ) from a user which shows about half of my measurements, so it may be that Hank reduced the power consumption in later models. Nevertheless I think they are quite high.
This is why I think it is important to have an easy option to mechanical lock out the lights. All of Hank lights I own has this feature. I own D4v2, KR4, and D1v2. And the heads of the lights can be turned only slightly to mechanically lock out the lights. Moreover, the lights are designed so that heads can be turned easily: KR4 has small vertical slits, D4v2 has the switch bump, and D1v2 has large cut out. I hope the production version from Wurkkos has the similar features.
