Flowering with Cree bulbs

According to Cree the 75 w equivalent bulbs have x-bd and the 60w equivalent have x-te.


that pic shows nothing and doesn't prove anything by showing the casing. You have to zoom in or magnify the led's themselves and see the bin numbers.

I couldn't find anything about Cree using x-be on the house hold crees. The flood lights may have them. We have been talking about the globes. According to Cree and the ones every one has picked up even me have the x-te. I'd rather have x-te over any other Cree.

That's a tear down of the flood light and compared to the globe. Who ever told you the globes and flood lights look the same now lied to you. I was at home depot earlier they had alot both.. Cree makes 2700k, 5000k, 6.5w, 9.5w, 13.5w globs and 2700k, 5000k , 19.5w flood lights

You said they look exactly the same even the boards. Use your words better.

Who gives a damn!!! This WAS an informative thread. Anyone have a link or tutorial on bending the lights in a more forward direction?! I don't mind the socket and cord...I do mind reflectors UGH!!! If not I can easily prop a y split in the mid sections. I used stripped 60w A19s, exactly 2" away from 2-3 day old seedlings for 18 hours, and they LOVED it. That was enough proof for me. Thinking about a 4 x 4 with my two SG-160s spaced apart, and the A19s surrounded under canopy. I'd like to forward face ones for the corners.

This would be so great if someone could remove the bulb, face all LEDs one way, attach heat sink and stull use the screw in lamp component. Not thinking this is straightforward, and you'd likely be further ahead to build small maybe 25W panels, and place them around.

By the way...Area 51s are everything they're hyped up to be. 15 min on after dark and leaves had to be at a 45* angle!

We all owe CaptainM for planting the idea seed! I had no qlue about house LEDs until I came here. If he had forward facing light, he could have used half the bulbs or maybe even got 2gs'/w.

Agreed. The Bulb LEDs are great for a home (I have them) but could be more efficient for growing the Canna.

HD wouldn't let me keep my half melted broken diode bulb when I exchanged it. Lady asked why would I want that lol. I didn't tell her I wanted to do a repositioning experiment.

This looks like a fun project

Very Cool! I am really moving away from the single light source concept. This opens up a whole new ballgame.

I'm really digging the wealth of LED knowledge here. I wouldn't mind a warm heat sink to combat this Midwestern weather. If I had my choice I would go vert with this 900w beast (thanks Hyroot) and supplement with LEDs.

The inefficiency of HID, in contrast to LED had me very interested initially.

Then I looked at if it could grow. My buddy's second grow ever. My LED panel:





This is simply a matter of dialing in the red and the intensity. This 300W panel I'm convinced kept Round I plants from stretching. That and the need for more red. No prob. We're used the Halogen for the red supplementation, and raised the lights. BOING! Round 2 shown here has the lights raised and red added 10 days ago

So the LED is efficient and can clearly grow great weed. Little more near UV and UV?- yep, probably. More red above 630? Sure. But these are easy

You should care. The bulbs Cree are making now aren't the same bulbs captain morgan used, probably cutting corners. The 2700k are worse on paper.

Do you work for Philips?

Yeah I work for philips, that's why I'm putting 20 flattened Crees on heatsinks to make a massive Cree directional hood. You're a moron.

I just got off the phone with Cree customer service. They offer the a19's with both x-te or x-be now. Just read the serial number on the packaging. They are going to email me with more info. Depending on the home depot. Some locations do not honor the warranty. You have to deal with Cree directly. The x-be has more yellow and green with the 2700k but less with the 5000k compared to x-te. Bothe have same amount of blue and red. Spectrum charts are on the data sheet pdf's on crees site

waiting for the apology now. So now the question is are the xb-e worse than the xt-e, which morgan proved worked very well. On the Cree papers the 2700k looks worse for the new LED.

You need to quit working on panels and start working on your people skills. Your project sounds interesting...keep us posted in a civilized manner k.
