    Worked fine for a while

    I have had these six months working mainly 3-5 hours per day. The first one started flickering every minute after 3 months. Just today another one started. The halogen bulbs these replaced lasted a year and a half under the same usage. This ... Read more

    3 out of 5 eggs Nice light, but. . . .

    Pros: Low energy consumption, fits in a standard GU10 Base, bright light - not quite as bright as incandescent, but MUCH more energy efficient.

    Cons: We bought three and installed them in October of 2013.The first one failed in February 2016 - flickering - like some of the other reviewers report.

    Bottom Line: For an inexpensive GU10 LED bulb, this one is not too bad, but we wish we had bought one with a three year warranty instead of one year like these have. The claim is 25,000 hours of use - about 2.85 years. We got about 2.25 years of use, but that was not with the bulbs constantly on - they're only turned on when we're in the room.
    Meh.

    Pros: These bulbs are a good replacement for halogen bulbs, they stay cool to the touch, unlike halogens which get extremely hot!

    Cons: None so far.

    Bottom Line: Good replacement bulbs, made my electric bill go down.

    1 out of 5 eggs JUNK - do not buy!

    Pros: Inexpensive

    Cons: They ALL will fail
    Chinese junk

    Bottom Line: These were just the thing I wanted to replace the energy hog and HOT halogen bulbs. They were great - for a few eeks, then one by one, they all started flashing intermittently until they would fail completely. I bought 5 and ALL 5 had this happen to them.

    Don't waste your time and money on these.

    3 out of 5 eggs Half-life of two years

    Pros: Nice warm color, low heat generation.

    Cons: Out of the four I ordered and received exactly two years ago two of them have failed in the last month. I expect more out of simple solid state devices.

    5 out of 5 eggs Great LED spot light bulb

    Pros: Crisp, bright white light, about 50 to 60 degree emission cone, homogeneous brightness in the illuminated area. Operates cool (the bulb itself) and doesn't produce infrared heat that a halogen bulb would generate. Runs off 120 volts line voltage - no transformer or adapter required. The ones I bought in Jan-2014 are UL approved (since that question was asked in the Q&A section).

    These bulbs have been working great for me. I bought a few GU10 sockets and built my own fixtures - under-cabinet lighting for the kitchen, closet light bar, desk lamp, workbench gooseneck light. The bulbs are lightweight, ver compact (50mm diameter, about 45 mm front to base) and do not require any external reflectors - the light emission pattern is shaped by the LED placement and built-in reflectors.

    Cons: none

    Bottom Line: Please note that these are GU10 bajonet socket bulbs - take a look at the product pictures. They have two pins that mount in a two prong GU10 socket. If you wnat to sue them in a standard E27 threaded bulb socket you'll need a E27-to-GU10 adapter.

    4 out of 5 eggs They are great BUT!!!

    Pros: They are a better option than the halogen versions, cost less to run,and produce no heat.

    Cons: The only issue I had was they are not as bright as the halogens I had, and I ended up purchasing four of them and one of the four was a lemon. It would just flash like a strobe light. So I have 3 RLLB-12001 in my fixture and one halogen to light up my living room.

    Bottom Line: Overall they are great lights if you dont get a defective one.

    4 out of 5 eggs Works just fine

    Pros: Connects to GU10 with no problem. Much less energy consumption than my old halogens. Much less heat as well

    Cons: Just a little less lumens than my halogens. My wife's wedding ring doesn't shine a well under these either. Not recommended for a jewelry store :).

    5 out of 5 eggs Great bulb

    Pros: Very little heat compared to normal to normal halogen bulb. Using much lesser energy. Bought 3 of these and replaced them all. No more guilt turning them on for longer hours.

    Cons: None. Still working fine. May be slightly dimmer than normal halogen bulb but that's ok.

    5 out of 5 eggs Great LED bulb

    Pros: These are great. I bought 1 to try when a halogen bulb went out. I replaced all of these types of bulbs in the house I like it so much. The bulbs stay cool and use a fraction of the electricity. I also like the color which is a little whiter (bluer) than the halogen ones.

    Cons: None

    Bottom Line: These will last a very long time. I hope some of the CFL bulbs burn out soon so I can replace them with LED.
