Review by Rich for Clear Panel Light Bulb, 150 LEDs, Warm White
Rating:
This product is probably my guess comparable to a 40 watt bulb. It has a light yellow light hue coming from it. A little to yellow for me. It is a little pricey for what you get, but for sucking only 7 watts I can afford to have the kids leave the light on and not pay through the nose to supply power to it. It will pay back it price many times before it s time is up. There was bearly any heat coming from it after leaving it on for hours. I also put this one in a frosted light fixture.

Good for a directed reading lamp. Will give low light to a room. Gives off about 40w Strength. OK, not like the CFL it replaced. We can put a man on the moon, but can’t yet crack the LED technology issues.

Review by Arthur J. Eldridge for Clear Panel Light Bulb, 150 LEDs, Warm White

This bulb is pretty expensive and does not put out enough light to read by from 3 feet away. I would say it is about the same amount of light as that from a 40 watt bulb.
