PACKAGING: 1/5

Things did not get off to a good start with the Lighting Science Definity. While the plain white cardboard box looked undamaged and had retained its structural integrity, the LED bulb was physically loose inside the box.

Upon opening the box the problem was clear; the box and its two cardboard inserts, designed to hold the bulb base and lens vertical during shipping, were too big for the bulb. The top insert didn’t even make contact with with bulb! The bottom insert had physically torn open, most likely damaged by the motion of the bulb moving inside the box. The box itself was at least twice as big as it should be which only exacerbated the motion and force the loose bulb had during shipping.

In all fairness, the bulb itself did arrive to LED Light Review HQ undamaged and functional. The plain cardboard box is also readily recyclable. If Lighting Science used this same box design, but sized it properly to the bulb, we would have a very high packaging score. As is, the box is an almost total failure and likely results in broken, damaged, and otherwise compromised bulbs being delivered to consumers. Lighting Science needs to do better.


PHYSICAL PRODUCT: 4/5

The Lighting Science Definity A1910001-014 is a good looking LED light bulb that follows the traditional shape of an A19 incandescent light bulb. Perhaps the biggest stand out feature of the Definity A1910001-014 is its twenty-four curved cooling fins that taper into what appears to be a white ceramic bulb base. With its traditional shape and appealing overall aesthetics, the Definity A1910001-014 should be welcome in exposed settings.

The Definity A1910001-014 feels solid in the hand with tight seems and only the slightest of play between the e26 screw and the bulb base. The only other possible blemish we could find is what we believe to be a bit of white glue emerging between the bulb base and frosted polycarbonate lens.


LIGHT PATTERN: 180-Degree

The Lighting Science Definity A1910001-014 LED light bulb has a 180 degree light pattern making it suitable for downward light applications.  Due to the lack of omni-directional light, we do not recommend the Lighting Science Definity A1910001-014 LED light bulb for table top lamps (as shown).


QUALITY OF LIGHT: 5/5

We were immediately smitten with the soft, pleasant, natural warm/yellow light projected by the Lighting Science Definity A1910001-014 LED light bulb. Of the two dozen LED light bulbs we have on hand, the light color of the Lighting Science Definity A1910001-014 was most similar to the Philips L-Prize, but with a softer yellow light and considerably less lumen output (395 lumens for the Lighting Science versus 940 lumens for the L-Prize). Let there be no doubt that we are very impressed with the light color and naturalness of the Lighting Science Definity A1910001-014.

WARRANTY:

The warranty for the Lighting Science Definity A1910001-014 is 5 years.


CONCLUSION: 4/5

If you’re looking for a soft, pleasant, natural warm/yellow light, or want something that would work well with the light color of the Philips L-Prize at a much lower lumen output, we highly recommend the Lighting Science Definity A1910001-014 LED light bulb.

Boy do we wish we could end the conclusion right there. In order to really hit it out of the park with this product, Lighting Science must improve the packaging of the Definity A1910001-014. A strong product like the Definity A1910001-014 deserves strong packaging. That said, this bulb’s a winner. Highly recommended.
