DiCUNO ProOE E12 Candelabra Bulb 40W, CRI 98, Daylight White 5000K, 6-Pack

Good lights, but you probably need all 6 bulbs to make your room bright enough. For the lifespan, I only use them for a month. So need more time to prove. However, regarding to the CRI or Full Spectrum, I actually got a chance to review it. I have a x-rite i1pro2 spectrophotometer, which can cover 380nm-730nm range with a 10nm steps. I use a 95 Bright printer paper to measure the reflected spectrum during night. Please note that I measured it by hand, and my measurement cannot avoid all the interference or error (i.e. room light reflection), but the overall trends should be accurate enough. Here is the result for the spectrum of E12 5000k daylight: 1. The measured color temperature is around 5140k, very close to the advertised 5000k, I will say the difference could very likely come from the measuring error. 2. From cyan(500nm) to red(650nm), the spectrum is VERY VERY flat, which indicate a balanced color reproduction. I didn't calculate the exact R1-R15, but based on my knowledge, this is really good. If you are the colorist or photographer and know color science, I hope my measurement and graph help you when evaluating this product. If you would like to search for good lights for work or for life, or just want to enjoy the true-to-life color, you should consider getting high CRI lights. There are many other good and well-known brands providing high CRI lights, but this one is definitely a good choice to consider too.

Great buy for 220 voltage bulbs

These lights fit perfectly in my chandelier. They were super easy to install and create great light.

These light bulbs are great. They provide much needed brightness to dark rooms. We will be changing all of our ceiling light fixtures to these bulbs.
