I've had these since January and they've been great -- my cattleyas are looking much nicer now. https://smile.amazon.com/gp/product/B09H6X5P9S/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

I clipped them on to my windowsill and they're just above the top of my tallest catt. After some research, set the built-in timer for 12 hours. They might not be bright enough if that was all the light the plants are getting, but they're in a windowsill and just need a boost, so they're fine. They're definitely bright enough to wake me out of a sound sleep if I miss the alarm.

I’m using this grow light: Grow Light for Indoor Plants Growing, 126LED 6000K Full Spectrum Gooseneck Dimmable Plant Lamp for Seedlings Succulents Bonsai Plants, Timing 4/8/12H https://www.amazon.com/dp/B09H6X5P9S/ref=cm_sw_r_cp_api_glt_i_3GMERBYCCEWFTZP671MP?_encoding=UTF8&psc=1 It seems healthy otherwise and is producing dew, just isn’t getting much color.
