    I recommend this product


    I was looking for full spectrum bulbs that fit a standard lamp socket. I was able to find a lamp store that sold adapters. So it is all good. I didn't realize that light bulbs could be so complicated. The store I found them at discontinued your line of bulbs due to California laws, The only place to get the bulbs is at specialty stores. Thank you on behalf of the current set of tomato starts.

    Thank you

    Ordering and shipping were on the money. It was probably one of the easiet item I have ever ordered on line. The bulb was shipped and packed very well. It truly is an asset on my desk at home where I spend quite a bit of time. I highly recommend these products Veralux sells and the stand behind their product Kudos to you Veralux!!

    The extra light bulb I haven't used for the new desk lamp, of course, but it looks fine and good quality.
