DC LED Lights While Equalizing

I'm noticing that some 12 and 14 VDC LED lights out there have a voltage limit below the equalizing voltage, and pretty maybe a bit too close to the absorption charge for comfort... My goal is to be able to not rely on a DC to DC rectifier or AC inverter for most of my needs, other than a 13.8 volt regulated supply for my radio gear and other DC electronics, and an inverter for short term AC loads, so I want the DC lighting to be directly from the battery bank...
Anyone have any hands on experience with this?

Re: DC LED Lights While Equalizing
paul..,
I have NO hands-on experience, but a friend blew up some LED under-counter lights by using an unregulated wall wart to power them.
You may want to run LED lighting from a regulated power supply. THis may be a pain if the LEDs are distributed around a room or in a number of rooms.
This high-ish voltage charging cold batts, and EQing them (particularly using 12 V), is one of the main drawbacks of direct DC loads on batteries -- the voltage variation on battery systems is often just too great for the direct loads. Many 12 V inverters shut down at around 15 V DC, which can also be a bit of a pain.
