No idea about lights but you should be saying whichdirection you want to expand your collection. More Phals? or other Genera orchids?

Thanks for your response. I'd like to have some paphs as well. Mainly, for this space, the floodlight concept works really well, so I would use non-fussy orchids that are compatible with space and light restraints without pushing the envelope. The specific bulb I planned on using is the the 120-watt Phillips Agro. I thought I'd suspend three of those over an 87" ledge, but two may be enough. If I learn that the "Agro" isn't that great, even as a supplement, I could go to a full-spectrum LED flood. I just wondered if anyone was using or had used the Phillips and had results to report. Thanks.

I would suggest using LED flood lights. Initially cost more to purchase(@ $20 ea), but they are cheaper to run, they last longer and they don't produce much heat. I use the 23-27 watt variants, which are equal to 200-250 standard watt floods (I believe). Three across an 87" window would be a good supplement, I would be sure to get ones with a wider beam/cone of light to cover the entire area. As far as full spectrum, I usually look for something in the 3000-5000 Kelvin range.

I generally purchase mine from a big box store/Lowes.

Good luck,

Bob

Thanks for the tip, Bob. I'll look into them.

Bob, I found these on Amazon. Having no luck locating LED floods on Lowes online. Are they the ones you suggested?

Two-pack for $50, 5000K. They seem pretty neat. Thanks.

John,

I would think those bulbs would cast too much light sideways and upwards, thus not being too useful for the plants below. The ones I use are more along these lines: LED Floods at Lowes. I usually can find 27 watt LED floods for less money than the $35 shown for these 32 waters.

Here's some more from where I occasionally buy on-line, 1000 Bulbs LED Floods. Be sure to notice the beam angles listed.

Yep. I noticed that the ones I found at were "multidirectional". Thinking that they might be the ones you used, I figured the shop reflector would compensate, and hopefully it will. Thank you for linking me to the GE ones. I can try both. Mainly, it's great to know a little more about LED development during the period I haven't been growing. Thanks Bob. (I think I recognize your moniker - aren't you a GardenWeb "old-timer."?)

Update on the multidirectional LEDs. As you predicted, Bob, fairly useless. I didn't realize that ALL of the light comes out from the sides and none of it is directed down. They're now in my utility closet with the rest of my extra bulbs hoping for use some day. Also, the 5000K color, offputting for an inhabited room. I've located some of the 3000K 250 watt floods that you describe, Bob. One maker seems to be replacing them with 5000K bulbs. The 3000 were comparatively rare. The other maker's version are a bit more expensive. I've ordered three to start. None were on-hand at my local Lowes or HD.
