I like what I am reading about the Home Depot Cree bulbs. Can anyone post a picture of the package? Or just tell me the exact name, and what to look for. Thanks in advance.
Which Home Depot Crees?

what would you guys use, the cree 9.5 bulbs or the philips 19.5 reflector bulbs?
what about the cree 9.5 round bulbs or the cree 9.5 "flood" bulbs. aren't they the same on the inside? stick going around a center mount and not facing down?

Im kinda in a bind here. What is best for a 2.16'x3.6' (7.776SF) space? A bunch of cree 9.5's? or maybe the philips 19.5 floods? I have to pick them up by tomorrow and am scrambling my research like mad! give me some examples of how a man should light this area up! Bulbs and spectrums from home depot, then I can focus my research time before travel to the city.

the floods would have better penetration but would require more precise angles... the crees shoot light in all directions so a reflector would be useful
why not get 1 flood light for each plant for above the plant and then put a hanging cree inbetween each plant

9.5 cree / 19.5 philips better than a 42W CFL?!

The 9.5W are give you the most lumen output per watt. Followed by this bulb then the 65W flood light CREEs. Every light in my home is powered by one of the 3 now. LOL But I was liking the flood light style because the light spread was more directional. The way I saw it is what the hell does it matter if you get more lumens in gereral if you are spreading too much and wasting a lot of it. I would think you could get the most out of the 9.5Ws in some sort of reflector with the bulbs fixed horizontally since the diodes are arranged in a cylindrical fashion. Though again as far as the reflector/light spread, that's not proven just theory.
But for example the 9.5 regular versus the 9.5 floods in my kitchen the 9.5 regulars didn't light as well as the 14W CFLs they were replacing, swapped out for 9.5 floods and the kitchen was much brighter than both the 14W CFLS and the 9.5 standard A19. Even have before and after photos to show it.

i never saw 65W Cree flood, its directional? I thought all the cree lights including the 9.5 flood are cylendular

Sorry I should have been more clear. The light spread appears much more directional. I know the standards are for sure cylindrical, but I'm not positive about the floods. They could also be, sorry wasn't trying to imply the diodes are actually facing all the same direction. Though if you just plug the two in and look at the distribution you see the standards through most of the light out the the sides and the floods the light is beamed down at more of an overall 90* beam. I might have to pull one of those suckers down real quick to see if I can see anything inside, you can get a little glimpse on the standards but paid no attention to the floods.
Yea can't see shit inside those ones. But just looking at the bulb on there does seem to be a bit of a dark spot in the center so yeah most likely cylindrical too. Perhaps why they are both 9.5 but the standard has a high lumen rating because most all of the light in the flood is reflected. uh uh. Not sure if they are even the same internals though honestly.

The flood lights are your best choice. They come in all different wattage equiv., up to 120w. I think it was the phillips that has a lens that can be unscrewed for a wider light pattern. Homedepot has the 75w equiv. for under $20. 4 to 6 of these would work good. I've tried the round one and they are a waste of light.

That's not necessarily true, you need to look at what diode each lamp uses. With the home depot cree's they use XT-E and XB-E, the spectrums look close but the efficiency is not the same. You will need more of the XB-E's because they aren't as efficient as the XT-E plus the floods are more expensive. The Cree A19 with XT-E's is the best you can get for price,spectrum and efficiency. People have said that there are A19's with XB-E's too so you need to check which one is carried in your home depot. The XT-E has 20 dome shaped LED's and the XB-E LED's are cube shaped.
Here's a tear down that compares the two LED's
Flood BR30 with XB-E's $20 650 lm
Standard bulb A19 with XT-E's $13 800 lm
Look at the other tear down reviews on this site too.

There are no longer any of the 2700k Cree WW's with XT-E, you can find NOS with the older heatsinks. All of the xb-e's are the Soft White 2700k with a newer version of the heatsink. 6w and 9.5w versions. The new 13w's are all xb-e.
Photos in the my gallery to see the heatsinks. Yes, I have many of the bulbs and have take the covers off just about all of them.

Are you sure they just don't stock them in your area ? They have plenty of 2700k 9.5 watt A19's with the smaller heat sink by me. They make 3 different 2700k A19's,one is 9.5 at 800 lm one is 13.5 at 1100 lm and the third is 13.5 watts at 800 lm. If you compare the A19 and BR30 that both draw 9.5 watts at 2700k the A19 is XT-E 800 lm and the BR30 is XB-E 650 lm with a larger heat sink. I think the 13.5 1100 lm is probably XB-E with the larger heat sink,the BR30 9.5 has a larger heat sink at 650 lm.
I left out the A19 40 watt equivalent.
I'm going to buy a new one and crack it open.

^ Yes, what you have is new old stock, so buy them while you can. The Xt-e's are labeled as the Warm whites and the Soft whites are the 2700k Xb-e's as well as the new 13w versions. They have done a complete change over.
You can't get them online [the warm white 2700k's]. Everything has become soft-white. I stopped seeing the warm whites in Oct 2013. So its been awhile.
