Review on 🌟 CRLight 6W Dimmable LED Candelabra Bulbs: 4000K Daylight White Illumination at Your Fingertips! by William Pacino

So here is my first 1 star review. I was happy to find 60W LED chandeliers with color temperatures above 2700K but not as blue as 5000K. When I first flicked the light switch, the light was as bright as expected. After working on the computer for a while, I noticed that the room was noticeably darker, which I thought at first because I was staring at the computer screen for too long. The next day the same thing happened, and a few days later I found out that the power outage was real. Then I ordered another version of the CRLight bulbs, same result. I am familiar with LED output efficiency and drive current. More current gives more light, but there comes a point where the LED will overheat and the physics of light conversion become less efficient, degrading light output. So I did a test. I ran a simple test comparing two versions of CRLight bulbs and a GE bulb from a major department store. - CRLight 4000K, equivalent to 70W, 700 lumens, transparent torpedo candelabra - CRLight 3200K, equivalent to 60W, 500 lumens. , Frosted Torpedo Chandelier-GE Relax 2700K, Equivalent to 60W, 500 Lumens, Transparent Torpedo Chandelier. The lamp is designed for 3 lamps (3 lamps were used in the lamp) and is open at the top. I placed the light meter about 2 meters from the light and didn't move its position. I'm not claiming that the meter is accurate, just that relative lighting comparisons are reasonably reliable. My eyes agree. I flipped the light switch and immediately began recording the resulting light every 10 seconds for 5 minutes. The test was repeated for each set of lamps. I have illustrated each of the lamp types in the attached drawing. CRLight bulbs have amazingly poor light output even for a few minutes! Both types tested lose about 45% light output by the 5 minute mark and this was quite noticeable even without a meter. On the other hand, the GE lamp lost less than 7%, which is a reasonable calculated tally. Please note that this is not permanent. If the bulbs are allowed to cool and then turned on again, the light output will return to its initial value and then degrade again as the bulb warms up. This is a classic design problem for beginners with LEDs. Note. The GE lamp is slightly larger with longer filaments, so it looks like the GE designer knew how to keep the total current and power density under control. My guess is that the maker of CRLight simply took a lower wattage bulb and ran more current through it, regardless of the side effects. less light output may be ok.
