For the price this light is actually pretty good for seedlings,lettuce and other medium/low light plants however I'd like to see a spec sheet about specifically what wavelengths the bulbs are rated for.

For those complaining about the red/violet color; Target absorption wavelengths for efficient Photosynthesis (chlorophyll A & B) in is around the 600-700nm(red) and 400-500nm(Blue) anything outside of these bands are typically of little use for green plants.

Individual LED's are manufactured and tested for specific wavelength,Light angle, and power outputs

Any Led light that expresses almost all white may be good for general indoor lighting but really inefficient for plant lighting.

I've been working on an indoor garden w/ a baseline of variety of plants & since my apt. doesn't face South I've been making do w/ the little sunlight that comes in. Hence I chose to get these grow lights. I'm not sure what anybody else means about these not being bright enough but there is always a way around issues like that. I got small portable lamps w/ can-like tunnel openings that can channel the light directly onto the plant (s) you want for just under 13 dollars. This helps maximize the amount of light emitted from these LED garden bulbs by way of channeling. Plus, the 2 wattage is great for the electric bill. I'm happy w/ thees light bulbs. The seller always comes through w/ terrific results. If you're starting out w/ an indoor garden then these are the light bulbs for you.

One of the reasons people get such wide results from this light are that people don't have a light meter to measure the output of these lights. I do. When they are new, they put out a lot of light. Yes, it's red/blue and your eye is weighted toward yellow, so you don't see it, but the plants do. However, after several months I have tested the same lights with the same Digital Light Meter and on about half of them, the output is way, way down. So if you are okay with paying $20 for bulb that only lasts 3-6 months, this is a very good bulb. But if you expect a $20 light to last longer than 6 months, then this is not the light for you. Sometimes you get one that lasts for a long time, but it's rare.

Honest reviews on Miracle LED 605020 Grow Bulb, Red and Blue

I am pleased with the performance of the light. I have had it since Christmas 2009, BUT it only works for ONE plant at a time. Not well explained--and very pricey to just light a single plant. I am an avid indoor gardener. No way could I afford to light my entire collection with these.

I really wanted to like this light, but believe me when I say the output is minimal. I have orchids in a north window that needed extra light and I can honestly say that apart from a barely noticeable glow this bulb provides no increased lighting. The package and Amazon description claim equivalence to a fifty watt bulb, but the new packaging includes the note that the output is only 150 lumen, far less than the 650 lumen of a traditional fifty watt bulb. If that information had been included I would have bought a different bulb.

Update, April 2013: While I stand by my criticism of the package claim, I must admit that my Alocasia does in fact have darker looking leaves under this little light. I now give it two stars.
