This was a replacement bulb for one that broke in the original order. This bulb has no problem. Works great! Thanks for replacing!

One of the bulbs was dim, so I ended up using an old bulb and a new one. The one that it bright is great. Fast shipping and careful packing and shipping.

I bought these for my grow light setup, and am happy with the lights. They shipped quickly, arrived unscathed and the long 4 foot deep box they came in is now my parrot's favorite play toy.

These bulbs are working very well as replacements for old fluorescent tubes in our garage. The color temperature is a good match for bulbs we had before.

This product was exactly what I needed for my kitchen but was unable to find anywhere locally. No one could beat this price online, and they came so quickly! Will most definitely purchase from here again!

I was not able to find this particular bulb at local stores. Fortunately, eLightBulbs was able to quickly send the right bulbs to me.
