http://www.ebay.com/itm/221461932701 - this is the 2pc from MarsHydro
http://www.ebay.com/itm/2PC-300w-IR...335?pt=LH_DefaultDomain_0&hash=item2c888160d7 - and this is the GalaxyHydro version.
Price is basically the same. 2 differences I noted were that Mars offers a 1year warranty, and the Galaxy offers 2 years. Also Mars is 5w led's, whereas the Galaxy is 3w. So I'm concluding that Mars is more powerful since it can support more wattage? I will go with the MarsHydro as long as they get the stamp of approval from those experienced with their product.
Jack,
Give the GalaxyHydro units try. Here is what I learned about the MarsHydro units today. The MarsHydro 300w old model LED is a great little grow light for autos. I have 2 of them myself. From the Mars website they had a 2 yr warranty but they cost $100. On eBay the same light was $78 with a 1 yr warranty. They were 180 watts actual power. It seems MarsHydro was fighting a battle with a couple of other companies that were making knockoffs of this fixture. Maybe 3 weeks ago I noticed that Mars took the 300w old model off their website. This was about the same time I bought my second unit off eBay. By now the price had dropped to $67.00 shipped to my door. While my second fixture was in route to me all of the MarsHydro resellers on eBay switched to a different model of the mars 300w LED. The "new" 300w model is only 125-130 real watts and only has 1 cooling fan now. I was worried about what I was going to receive in the mail and luckily it was the 180 real watt version. On one of the other growing forums I have been told by a MarsHydro rep that the 300w "old model" has become their eBay price wars model and they made changes to be able to drop costs. So with that said give the Galaxy a go and let's see how they do for you.
I received an order from Mitch for Sour Crack and Deep Blue C's a few weeks ago. It took 7 days to get to me on the east coast. I used their regular 'free" shipping method and it was more than enough and would see no need for the "super stealth" method. I love the 10% AFN discount and the number of freebies they send is GREAT!
