Growing Cattleyas under PAR38

[Mor]

Hello!

I am growing few orchids which required high light such as Cattleyas, Brassovola Nodosa and similar. Because I have only northern window my orchids didn't bloom.

I recently purchased the ALT PAR38 LED 60 degree 30 Walt bulb for my Cattleyas.

The salesman told me that this bulb is "perfect" for cattleya's growing. Unfortunately when I measure the light it's seems that my orchids gets 17,000 LUX ~ (1200 FC ~).

Do you think it's enough? What do you recommend me to do? I have no sun at my flat and I really want them to bloom. I'll appreciate any kind advice!

Do you think I should buy more bulbs?

I attached photo of the bulb package and photo of my growing shelf.

Thanks!!!!
