I purchased a Lalizas Classic
LED 20 All-around & tri-colour light to replace a very old one that was disintegrating. My old one was a Lalizas and externally looks just like the new one. I expected changing the fitting would be straight forward. But I cannot unscrew the new casing from the base. It is just too tight.
Iíve tried letting the base heat up by direct sunlight hoping it might expand a bit. Iíve also tried heating
the base carefully in hot water
, neither has be3n effective. I havenít tried to apply any lubricant because Iím not sure what that might do to the plastic.
Also, Iíve only tried to unscrew it by hands. No tools.
