Bests & Worsts Reviews from Amazon

Purchased on Thursday and received on Sunday, Took only a half a hour to install on my deck cover using cup hooks. Great looking lights ,may get the dimmer in the future. All the lights work and have one back up. Only concern: Can not find back up bulbs, Anyone out there knows where to find ? Special type of LED bulb. Looked all over Amazon and the internet with no luck. Seller said they will provide some back up bulbs, will update once received. UPDATE: Seller has provide 2 more extra bulbs at no cost. but this bulb is nowhere to be found other then the seller. Being LED they may last years, time will tell. Update : Finding replacement bulbs is imposable , The bulbs that were recommended were totally defective, tried twice and the bulbs provided by the seller would flash for a split second and blow. Would be happy if working back up bulbs could be located. Have two blown now and I guess as they go out no working replacements will be available
