Battery pack
5200mAh lithium-ion, 3.7V. Fits both sizes. The battery is the part most likely to wear out — after a few years a full charge holds less, and the light runs shorter.
REPLACEMENT PARTS
Keep it running
for years.
The battery pack, the LED + MPPT module, and the remote are designed to be replaced. One module fits both the 12-inch and 15-inch light.

LED + MPPT module
The integrated light source and charge controller. Fits both sizes. If the light stops responding after a full day of sun and fresh remote batteries, this is usually the part to replace.
Display remote
The same remote controls either size, and can operate several lights within range. Requires 2 AAA batteries. A blank display is almost always the batteries, not the remote.
Mounting base & hardware
Size-specific. The 12-inch and 15-inch lights take different bases, so tell us which light you own before ordering.

Not sure which light you have?
Measure the top: 12 × 12 inches is the 12-inch model; 15 × 15 inches is the 15-inch model. If you bought on Amazon, your order history shows the listing.
It may be covered.
Warranty runs from the date of purchase: five years on the housing, solar panel, and the mainboard with the integrated MPPT module and LED; three years on the battery pack and the remote.
