Failing after only a few months use.

I want very much to like this light, however the unit appears to be very flawed. After only a few months of use the lenses are starting to turn brown due to the UV emissions of the light. This having been said the fixture is otherwise well made and I am able to measure ~1000 umol before plants start showing stress. Plants are growing well, however the UV compatibility of the lenses will need to be addressed before I can give it a better rating.

Edit: Jan, 31 2016. Email contact has been made, pictures provided.

Edit Feb, 1 2016. I have been assured the issue is being resolved.

Edit Feb, 10 2016. Just received news, a special order of P150's I purchased in order to compensate (overkill but needed otherwise) has shipped. No news on R/R for the lenses yet.

Edit Apr, 23 2016 Problem has NOT been resolved. Fixture has been returned at near a $100 out of pocket expense and am awaiting refund.

Edit May, 1 2016 Tracking: Delivered On:Tuesday,  04/19/2016 at 11:28 A.M. Still awaiting refund....

Edit May, 16 2016 STILL NO REFUND!

Edit May, 18 2016 I Have sent emails requesting refund. Amazon Customer Service has sent emails requesting refund. NO RESPONSE!

Edit May, 20 2016 Still no response, an A-to-Z case has been opened with Amazon.

Edit Feb, 5 2017 This was without a doubt the worst purchase I have made in many years. I did eventually return the unit only to have them "lose" the unit for months and not refund. They only way I secured a refund was to post this review to every product this guy has posted on Amazon. He negotiated; I received my refund and the negative review was confined to this product. He did say he was going to send a second unit so that I could give him a chance to redeem himself, however he did not follow through.

Died after just under 2 months of use. Started receiving SD card errors on my cell phone a few days ago and now the phone doesn't recognize it at all and can only read some of the files off of it using a card reader.

Not very well made. This is what happens after a couple of month use.

After only using this device for about month, it stopped working and is being returned.

Sadly, this product failed after only 4 months of very light use. It worked great while it worked but now it's dead. Will try to get a replacement under the manufacturer's one year warranty.

Worked great with light use for a few months, then stopped working yesterday.

I originally gave this product a 5 star review but after it failed today, after less than 2 months use, I'm downgrading the grade to 2 stars and that's probably too many!

It's only been a few months -- I probably used it a few times a week and now the bluetooth connection is faulty; my phone / device will connect with the speakers, start playing the music, and then the signal will be dropped.

Worked fine for a couple of months. It will no longer take a charge.

My cables lost their ability to stay connected rather quickly.  Doesn't "click" when inserted anymore after only a few months.

My unit worked fine for about 3 months and then failed.  I'll return on factory warranty if I can find out where to sent it.

Worked great for a few months. Recent development is that it stopped working and I need to figure out why.

Worked for a couple of months and then would not hold a charge.

I bought them just a few months ago and one of them have already failed. The white completely failed. I'm very disapounted! I expect it after a couple of years not 2 months.
