This was my second try at replacing a PAR20 incandescent with an LED. I've been testing LED's with both a Trifield 100XE EMF Meter and a Stetzerizer Microsurge Meter and found that both LED's and fluorescence's generate some line noise and an electrical field around the bulb....so bad in the case of a previous PAR20 that the remote switches on my X10 system stopped working. This bulb was relatively noise-free. It is also very bright white...perhaps a little whiter than I preferred, but totally acceptable.
The bulb was shipped from China so I was prepared for shipping to take 30 to 45 days... but it arrived in only 10 days. A quality bulb at a low price, shipped free and relatively quickly...hard to avoid as an obvious choice.
Sept 16 update: After about 45 days of 1 hour/day use, the bulb failed by starting to flash. I might have had a bad bulb or heat build-up might have been a factor since it was in a recessed ceiling fixture. For these reasons, I only reduced my review by one star; the bulb does have a 50000 hour guarantee but I don't plan to send it back.
Sept 17 update: I've been contacted by Lemonbest and they have already offered to send a new bulb or refund, despite me not asking for either...that is the type of customer service I rarely see! They pointed out that even though they test every bulb before shipping, it takes about 48 hours for any LED to properly age. Based on their quick and thoughtful response, I'm going back to my 5 star rating. Externally, the bulb is well constructed and internally superior producing so little electrical and magnetic noise. If they ask, I'll certainly return the failed bulb so their engineer can best understand any failures in the bulb.

I bought 3 of these to replace the lights in the bathroom. They are a little longer than the Sylvania halogen PAR20 bulbs that they were going to replace, but they were both PAR20 so I thought it would be OK. I was wrong. When I replaced one of the bulbs the cover would not shut tight -it was about 1/4th of an inch too long. The Lemonbest bulbs are longer than the Sylvania bulbs. I tried to use them in other rooms but they just wont do. The light is too white, not the yellowish warm light that I am used to. And the light is like a spotlight -it concentrates the beam in one spot.Best Deals for Lemonbest® Energy Saving 9W PAR20 LED Bulb Spotlight Flood E27
After a long wait for the slow boat from China, the bulbs finally came. They are the same size/dimensions as the standard Halogen PAR20 bulb. They fit a track light I use over my home office with an L shaped table top about 12 feet total length (8x4). Four of these 9 watt LED bulbs light up the area as well as 3 of the Halogen PAR20 50 watt bulbs did. The LED's are a stark white, almost blue, compared to the standard soft warm white of halogen bulbs. Had them a month and all 4 are still working. I did have to replace the dimmer switch that worked with the Halogen lamps with a standard flip switch for the LED's.The LED's do concentrate the light in a smaller beam than the Halogen spots did. They also run much cooler so I'm not getting cooked under them while working. I can hold my hand in front of the LED's at about 4 inches away all day. 4 inched from a 50 watt halogen will burn you in a minute or so.
So I am saving 114 watts over the halogen bulbs, but I did have to add a 4th light fixture to the track to get the same level of light. And its more evenly dispersed with 4 bulbs rather than 3. The Cool White color does not bother me for the office, and it actually makes reading papers easier on my eyes. Also have 3 computer monitors (LED and LCD) and none are affected by the LED lights. There was mention of a 48 hour "aging" time, but I have not noticed any change in color or performance of the bulbs.
BTW, the rest of the office area is lit by CFL warm white recessed ceiling lights. The desk area really stands out as being blue-ish compared to the curly 13 watt CFL bulbs.

LED is like LASER. Light does not disperse very well. Hope this lasts longer. Most LEDs do not last as advertised.
