e27 socket = screws into an ordinary light bulb socket you have in your house
146 LED = it uses very low wattage LED's, not the best efficiency
Red/Blue spectrum = Probably ~450nm and ~660nm to hit photosynthetic efficiency peaks
would they work = Yes, but to what extent? I recommend saving your money and buying some 2700k LED bulbs from Home Depot. They've got Cree and Philips bulbs for $10-$14 that are a nice value.

Are we talking about the LED screw-ins that can be bought from Home Depot? If so, yes, they should perform as good, or better.

LED bulbs should handily outperform CFL bulbs of equal wattage. And to a degree, they should also outperform CFL bulbs with the same incandescent equivalent while consuming less energy.

I would steer clear of the e27 ebay leds. I have had a couple of these bulbs and they are just plain terrible. They dont like 18hr light cycles. After a couple of weeks to a month certain section on the panel just stop working. Bumping is on the right track, definitely get some cree/phillips bulbs. There is a thread on here about using the 9w cree bulbs.
