That used to be the case in general.
Advances in LED development eventually led to the 'broad-spectrum/full-spectrum' ones, which can be used for growing orchids.
Most old-school regular LEDs from years back couldn't be used successfully for orchid or plant growing.
The ones that should do the trick are known as "LED grow lights".
