for me is good flow of water and try to place it under shade.. then it will open up nicely. however if it not opening due to stress just give it sometime to get use first
Selling at only $40. Super dirt cheap
casing abit of rust just need to remove the tube and give it a good wipe will do..
however this light set does not have a on off switch.. u have to on it by power plug.
