What are the right lights for me?

[marcoeverard]

I have a 10ft x 10ft orchid house but due to the design it really only has sufficient light for lower light plants. However i am very fond of cattleyas and would like to make one end of it much brighter to supplement the natural daylight that they receive through a glass block window.
The area I would like to light is 10ft long by 3ft wide and the orchids sit on a bench about 3ft from the ceiling. I would like to mount the light on the ceiling (although I know that closer is better) and wonder what kind of lighting would be most suitable and would appreciate any suggestions.so any thoughts on whether the LED floodlights like these are any use Would LED flood lights be suitable at all. These ones use only 60w and give out 5500 lumens? If so what would be best the cool white or warm white? https://www.ledhut.co.uk/led-flood-l...avaliable.html as they only use 60w but give out 5500 lumens
