National Tree 4 Low Voltage Dual LED Replacement Bulbs (RB-4LVD)

These bulbs are exactly as pictured. They have a long base and look exactly like the bulb I was replacing. They switch between color and white. I noticed after we put our tree up this year a branch was flickering and then a bulb went out. Went ahead and bought these after carefully comparing the two and it was a perfect fit. If you don't replace bad bulbs the life of your light set is reduced.

I have a 2019 National Christmas Tree Company tree with dual-color LED lights. When we set it up this year (second season) over FORTY bulbs were out. The manufacturer confirmed these are the replacement bulbs. What an absolutely ripe off price-wise. Additionally, as several other reviewers indicate, these do not fit. Even if you take pliers and trim the longer root off to make the bulbs the same length, the bulbs still do not work. From the side view, part of the base on one side of the new bulbs sticks down too long. I can confirm taking the guts out (as one other reviewer did) and putting them into the old bases works but is incredibly tedious and time-consuming. All around disappointed. Lesson learned, DO NOT BUY this brand tree.

I have this messed up outdoor led Christmas tree that I couldnt find replacement leds. These weren't the exact voltage I needed but as it turns out, they were close enough.....weeeeeee merry Christmas to all and to all a good nite

The bulbs didn’t fit so they had to be returned.

Like other reviewers, the bases of these replacement bulbs were too big to fit my Christmas lights. But they still provided exactly what I needed. I was able pull out the fresh LED bulbs from the longer bases and insert them into the (shorter) proper bases for my lights.Tips: you may need pliers to pull apart the light cover from the base. Make sure you orient your bulbs the proper way (otherwise the replacement bulb will be white when the rest of the lights are color and vice versa). If you have multiple light bulbs burned out next to each other, do NOT turn on the power until all burned-out bulbs have been replaced (if the power is unevenly distributed, you can burn out more LED bulbs - learned that lesson the hard way).

Very disappointed. These were pricey for what I received and They did not fit my light string. Waste of money. I couldn't return them since I bought them in October and the return window closed.

They all worked but the price seemed high. I used these to replace some that burned out. I ran into a few problems where u really had to push them in, to get them to activate.

I have a prelit Christmas tree from Costco. It has GE bulbs. Cannot find GE replacement bulbs so I got these.They do not work on this tree
