Basic Christmas lights. 200 green lights per strand. Installed 6 strands with no breakage and no problems. LED equals lower power draw. I've seen brighter bulbs, but when densley installed they are perfect. I use them to wrap tree trunks & branches. They are excellent for this. Ordered 2 boxes (4-strands) initially. Likes them so much I rush ordered 2 more boxes,Easy to hang. Looks fantastic! Very nice quality.I absolutely LOVE these lights. Perfect shade of red. (Sorry about the blanket in the pic) but with the light out from behind me it does them even more Justice. I highly recommend them.The word "TEAL" basically sold this product to me, but the 3 color string of mini-lights weren't anything like that. They came in a box that wasn't wrapped or sealed in any fashion. I bought the 200mini-light, so there were 2 strings(expected). Both strings work.However, the bulbs are painted, not like a transparent colored plastic mini-light bulb --- (think Christmas multicolored string lights).The purple was as I expected, a transparent darkened purple bulb. The orange is actually coated or painted orange and the 3rd color is GREEN--- bright(lime) green-- NOT a low key, ominous, darker TEAL. So the paint on the orange and green bulbs makes them so bright they completely drown out the darkness of the purple.I posted 3 pictures.. the 3rd has my own additional 'halloween purple' string against the multi string for referenceI used these to string over tables at my sons grad party. I alternated red and white. It gave the atmosphere a warm feeling. I was so happy with how these lights lit up the party.Very nice.XGreat light - there were more lights than I thought I was going to get.
