It’s starting to look like Philips has seen the light with their LED light bulb packaging. Like the Philips 409938 we positively reviewed earlier this year, the L-Prize winning 420224 is contained in a simple cardboard box with two cardboard inserts that keep the bulb upright and provide another layer of protection for shipping and handling. The entire cardboard package appears to be recyclable and does not need to be destroyed to access the product. It’s also quite attractive. Well done Philips.

Physically, the Philips L-Prize winning 420224 appears to be the albino twin of the Philips 409904. Where the Philips 409904 has a ribbed battleship grey base, the L-Prize 420224 has a smooth white base. Where the triple lenses of the 409904 are an intense yellow-orange, the L-Prize bulb is an even more intense yellow. The yellow lenses on the L-Prize are exactly the color of highlighter pens. You may have college exam flashbacks.

The three channels or grooves that divide the top lens are wider, more squared off, and travel deeper into the base on the L-Prize bulb. The base of the L-Prize is also very smooth and tapers into the three lenses with elegant curves. The fit and finish is excellent but you can see a little space between the base and lens seams. In all fairness, the Philips L-Prize bulb feels very solid and sturdy and looks more like an Apple designed product than any light bulb we’ve ever seen. Cupertino inspired design strikes again.

Taking a step back, the smooth white base and bright yellow lenses of the Philips 420224 L-Prize are more aesthetically neutral than the ribbed battleship grey and 60’s sci-fi orange coloring of the 409904. With it’s three lenses and unique shape, the 420224 is still odd looking for a light bulb, but less so. As die hard Apple design devotees, we love it. Tighten those seams and it would get a perfect score.

LIGHT PATTERN: Omni-Directional

The Philips L-Prize winning 420224 LED light bulb has been the subject of plenty of media attention and political controversy. For this review, we’ve put all of that hype and hyperbole aside and look at the 420224 for what it is, a LED light bulb.

The Philips 420224 projects a clear and warm/yellow light. It’s not overly warm/yellow like its cousin, the 409904. The 420224 isn’t even as warm as our reference 60 watt incandescent. With the L-Prize bulb, Philips has struck a keen balance between warmth and clarity.

Side-by-side with our other two favorite 60 watt equivalent bulbs, the EcoSmart 400-674 and Sylvania 78823, the Philips L-Prize was the closest to a soft white incandescent, but with more clarity. The Sylvania has an equally natural light, but with a cooler and slightly pink color quality. The EcoSmart is significantly cooler and clearer than the Philips, with a natural daylight color quality. All three bulbs are excellent options and offer the consumer a choice depending on light color preferences.

The Philips warranty for the Philips L-Prize 420224 LED light bulb is 15,330 hours over 36 months or 12,775 hours over 60 months.


The Philips L-Prize is an easy recommendation for anyone who wants an incandescent-like warm/yellow light. With its omni-directional light pattern and fairly domestic product aesthetics, the Philips is an excellent warm white incandescent replacement.

Is it the best 60 watt equivalent dimmable A19 on the market? Yes, and no. It’s certainly one of the best, and perhaps it’s the best if you prefer the warm/yellow light quality of a 60 watt soft white incandescent.

Before you make your decision, we recommend taking a look at the equally impressive EcoSmart 400-674 and Sylvania 78823. Lucky for you, all three LED bulbs are excellent options.
