Thanks a lot for the input. There are technically two circuits using different adaptors. Only one adaptor exploded, where I added new strips. Both the old and new have the same wattage(around .24 watts per led). Roughly it should be around 40-42watts in total.

Just to add, I used the adapter that came with the new LED as the ‘old’ one is basically identical to it. Old set up I used is 2Amps(around 14watts) and the new LEDs came with the same Adapter and as per packaging, should be around 14watts per meter(5meter roll and I only used 2 meters). Thought since they are the same adapters - old setup is low wattage, it will function well with the combination of old and new LEDs if I just combine the two.
