Yeah I'm out of weed, and have to take samples for monitoring & evaluation on daily basis
for all.

I've seen a couple of threads mention the led corn bulbs as a micro vert alternative, I was just wondering if anyone has seen these and the versatility they would provide in a micro grow.
They come in 30, 40, 60 and 75 watts. The 30's are medium base, and I think the rest are mogul base, but self ballasted of course. 5000k on every wattage, and 2700k at least in the lower ones. They are probably not as cheap initially as an array of lower watt bulbs, but it's not my main concern.

I think using one of those bulbs for vertical defeats the purpose. They are not a true 360°, like a HID bulb, so you don't get the full effect of vertical. LED lights are directional and most of the efficiency is gained by not bouncing light around in a reflector. My two pennies worth anyway.

I think you got me all wrong, I'm not talking about the ones blynx was so friendly to examine here, I mean this general type of light
Oh overlap, I hadn't seen the post by Bmeupscotty before posting mine...

They may not be a true 360° but the cob leds do have a rather wide angle. That lamp may be perfectly suitable for some smaller vert setups.I think using one of those bulbs for vertical defeats the purpose.

Chevy cHaze found one which looks even more suitable. This aspect of growing is getting a little crazy.
I had some dude hatin.
I was using a 16.5 watt 1230 lumen, a 14 watt 1500 lumen and an 11 watt 800 lumen for the first three weeks and someone said "you can't do this! this is a waste of time!"
I was like no, I could be waiting to get another light or anything. Plus now anytime I see any shade on my leaves I just direct my supplemental LED's onto them.

Coffee smelling weed? That's something I'd love to have. Anyone coming round would think I just made a pot of coffee. Cheaper than ona gel or a carbon scrubber
Early Bubba Hash from Ace. The one I had this spring smelled like black coffee. Turned gorgeous fall colors too. It's a low THC high CBD strain according to analysis and that matches my experience. Very little head, clear and more of a body relaxing effect.
Man, this is for micro growers, but with these 100 LPW screw-ins, you can just expand!
You can control color temp. You can direct warm on the tops and cool on the fans.
I now have 17 watt 1500 lumen Cree COBS.
Yes, screw-in Cree COBS! 45 degree and 25 degree. I heat up the soil of seedlings with it! Hahahahaha!
Also good for tomato plants and the pure white light man. Can't beat if for signaling and all around cartenoid..activity.
Did you all know that after harvesting a tomato, if you put UVB on it for like an hour, in a couple of days it's lycopene and other things increases by 1.6 times? Imagine for weed now.
Is there a UVB led screw in avail?

Not sure about UVB LED Spots, but I have a 25w UVB reptile CFL as the middle bulb in my 5-in-1 socket adapter. Works great, but I'm starting to think it might not even be necessary to add UVB.

Bought a 16 pack of 9'ish watt Great Value 2700K lamps. I now have a new bulb for the house, since one of the boogers has the dome glued on SOooooo tight, all I did was munge the plastic a lot. lol
The rest came off great. I'm seriously loving these.
@psyphish Do you have a link to the 17watt lamps?
