Robert You are correct it is only 5W.I complained to Banggood and they said the following:We contacted the supplier of the product inside and they said the product was correct. It's just a mistake in packing.That is plain nonsense.With two 18650 batteries you have 7.4VdcIn order to drive a 30W LED you need 30W/7.4Vdc = 4.05AmpsThere is no way two 18650 batteries are delivering that much current.They would soon heat up and melt.
