I'd have to agree with Magash on this even though LED is the future of indoor growing. Like Phrostbyte said, you'd need a a high wattage LED... to make any sort of difference. I'd say 3w is exceptional but you'd have to go higher if you want to see a difference better than HID.

Also, some things to know about LEDs: They still produce a lot of heat but it is efficiently directed to heatsinks on the back (an aluminum plate on the cheap one's from China). It's like having a cool tube built in from what I gather. I also read that blue LEDs fade significantly faster than the reds- I haven't come across any actual evidence of this other than people who say it takes more effort to produce blue wavelengths compared to red which seems plausible looking at the actual wavelengths. But the point here is that it's said replacing the diodes is not really user-friendly.

I recently read up on a test with 126w full-spectrum Hydrogrow Penetrator LED advertised as a 400w equivalent done by a trusted unbiased cultivator. Long story short- not only did it come up short with dry weight but also an extended flower time was insinuated.

-------------------

I'm not bashing LED, personally I can't wait for them to be marketed at a reasonable price with proven results. There are some kick ass proven LEDs out there and if you've got deep pockets, these I have found to be good sources:

http://www.gslindustries.com/default.aspx
http://www.cree.com/products/index.asp

One day, LEDs will outproduce HID but sellers are maiming their reputation by shafting us with these cheapos sold on hype not results. I was so mad I almost blew some money on some .5w crap because there's limited/mis-information.

---------------------

If you have to sacrifice yeild for stealth - LED
If you want closer to your plants potential - HID





Anyway, hope that clears some things up.
