Kitchen and Housewares Reviews of Grip 30 LED Light Bulb
Customer Review: Reasonable value, high efficiency, yet low light-level output
Summary: 3 Stars
Six months ago I purchased--on sale--a pair of these Grip 30-LED light bulbs from an Amazon vendor. Both bulbs arrived promptly and undamaged. The shipping cost for the pair was a bit costly, yet I was curious about utilizing them in a special application and to note how they stood up under constant use. One bulb failed within 45 days; however, the Amazon partner vendor promptly and politely replaced the defective bulb at no additional cost.
Be advised that the light level produced by this bulb is rather low and its resulting color hue is not warm (rather it is a cold, non-frosted white light). Nevertheless, the light level clearly is more than that produced by a typical solar outdoor garden light or any solar walkway light fixture; as was expected, the stability of the output of this 30-LED light bulb is constant.
In its current intended service, this bulb ensures that one always can see the walkway, safely climb the outdoor steps, and place a key in the door lock--all without blinding garish light bathing the grounds or facade of a period New England house. However, this 30-LED bulb is not suitable for all purposes and, thus, should not be purchased just to replace most of your standard incandescent light bulbs.
In its use as an energy-efficient replacement bulb screwed into a standard-socket outdoor wall lantern placed next to the entry doors of an historic house, this 30-LED light bulb has performed acceptably in continuous service for these past several months. As the outdoor lantern fixtures [wall-mounted on the facade next to the home's entryways] into which these bulbs are placed must be left on 24/7, the resulting electricity consumed monthly by both of these bulbs is negligible. This cost-effective operating factor, above all, has made the purchase of this 30-LED light bulb a sound and carefree choice for my special use.
At some point, moreover, I expect that lower-cost and brighter 60-LED or 100-LED (or larger) bulbs--perhaps with warmer hues--will be perfected for a wider range of applications.
Customer Review: We are LED lighting pioneers
Summary: 3 Stars
The three stars that I gave to this bulb are actually intended for Amazon and the LED and fluorescent lighting industry in general, not necessarily this 30 LED bulb. The problem, as reflected by other posters, is that I'm not able to reasonably predict how these bulbs are going to perform based on the limited information about the bulbs that we get from Amazon and other sources.
Beware, from this point on my paragraphs are not structured.
This bulb replaced a $2+ Sylvania fluorescent bulb in a bedside lamp. The fluorescent bulb was too big for the lamp; it protruded above the lamp shade and was too bright to look at, even in peripheral vision.
I miss the fluorescent bulb because of its warm color. I understand that our eyes are least sensitive to blue so the blue hue of the LED bulb makes the area gloomy. So learning from my efforts as a LED pioneer, I now prefer warm-colored LED lighting.
The bulb had a reduced price, $3-something. The shipping actually cost more than the bulb did. I had initially put the Sylvania bulb in the lamp because the lamp will be used only for a short while every day, more expensive LED technology deemed a waste of money; it would never pay for itself regardless of lower power requirements. So I don't regret the LED bulb because of reduced price.
I estimate that the actual power consumed by the LED bulb is much less than the 13 watt Sylvania.
I regard the cheap, blue hue LED lighting that I've invested in so far to essentially act like flashlights, directed beams, but without needing batteries.
I saw tiny fluorescent bulbs (2 per package) in Walgreens a few days after the fact. But I didn't remember the brand name and haven't yet been able to cross-reference them on the Internet. I would probably have decided on them, although I will note that even with the shipping, the 30 LED bulb was cheaper.
Customer Review: Be cautious as white-LED and blu-LED lights may have eye safety problems.
Summary: 3 Stars
I just learned from an article in Wikipedia that white-LED and blu-LED lights may have eye safety problems. I'm still doing research on the issue. Meanwhile, I've taken this white LED bulb off my desk lamp. Please see the following text I copied from Wikipedia:
* Blue Hazard: There is increasing concern that blue LEDs and cool-white LEDs are now capable of exceeding safe limits of the so-called blue-light hazard as defined in eye safety specifications such as ANSI/IESNA RP-27.1-05: Recommended Practice for Photobiological Safety for Lamp and Lamp Systems.[57][58]
Customer Review: Listing lacks most relevant information
Summary: 3 Stars
Absolutely every light bulb listing on Amazon should include the following information:
1. Light output, measured in Lumens.
2. Power consumed, measured in Watts.
3. Socket type.
4. MTBF, measured in hundreds thousands of hours
A mean color (measured in nanometers) would be nice too.
Customer Review: Color temperature
Summary: 3 Stars
Absolutely agree with Johnatan's review, and I would like to add:
Color temperature should be listed with every LED light bulb.
