I have 4 x RNG-100D panels and 40A Tracer MPPT.
My cabin is dual-wired (12v and 110v) so I don't have to use my inverter unless circumstances require. 12v is connected directly to battery bank.
Until recently I used 22W 12v flourescent lighting but have now replaced them with 8-10W 12v LED.
When the batteries bulk and then float at approx. 14.5v, the LEDs flicker or fail to come on, and one has already burned out. They seem to work fine overnight at 12.6v.
I need to somehow constantly regulate the voltage.
What do you recommend?
You should have your lights running from the CC not the batteries...... That voltage shouldn't change.... Change to 110v full time......

during absorption and float ya basicly have pwm, try differnt leds

Bird, You don't think he has it hooked up to the wrong place?? Shouldn't it be hooked up to the CC since he's running it like you are??
i had the same problem with my LED strips flickering. Now, I use these: eBoot 6 Pack LM2596 DC to DC Buck Converter 3.0-40V to 1.5-35V Power Supply Step Down Module
It keeps the voltage nice and stable at whatever voltage you set it at. Personally, I set mine at around 11.5VDC for the lights. I also use others set at 5VDC for charging USB devices (and for my VOIP device which runs at 5VDC.).
Each LM2596 can handle up to 3 Amps (36 Watts at 12VDC). So, you might be able to run THREE of those 10W bulbs on ONE LM2596 with a few watts of "breathing room."
Personally, I use LED strips for all my lighting instead of (singular) LED bulbs. Much less power needed for the same light coverage. Consequently, I'm currently lighting my entire home office space through ONE of those LM2596 modules.
