PHILIPS LED Ultra Definition Daylight Light Bulbs, 4-Pack | 800 Lumen, 5000K, Dimmable, Frosted Flicker-Free, CRI 95 True Colors, Glass Design, Up to 15000 Hour Lifespan

Had a problem with light bulbs flickering and bought these to replace them. They work great. Have not had any flickering since installing them.

I was looking for a high CRI light for photo shooting and color matching. Bulbs with the highest CRI like incandescent or halogen don't offers white light, so even though they are great source of color accurate light, they're orange. 99% of LED that offers 5000K white light in the market don't do well either with their low CRI, especially in R9 (red spectrum) and R12 (blue spectrum). My LED I brought 5 years ago has an R9 of 24 and R12 or 66, it is terrible. These Philips 5000K LED fills perfectly into this market its high CRI in all spectrum. I measured it with my spectrophotometer, these bulbs has CRI of 96, with R9 (red) of 87 and R12 (blue) of 85. They are the best value bulbs for color accurate works without spending hundreds or thousands on professional LED. I have read many complains about flicker in the reviews, I'll update in a month if I encounter it. But they are so far so good for me.

FINALLY!!!!!!!!! A LED bulb that does not flicker and can dim all the way down!!!!!

It works

You cannot go wrong with an LED bulb Hey, they are Phillips and have a good price on Amazon. They will probably outlast the light fixture they are in!!!!!!

Does not have the advertised voltage range. I bought these because our voltage fluctuates a little. Sometimes 105 volts, and 120V. The product description says the range is 100 to 120. But if the voltage drops below 120 they get a lot dimmer. Some high quality Led bulbs have built in circuits that give stable light output even if the voltage varies a little. The product description made it sound like these had that type of circuit, but they obviously don't. They work the same as the no name brand, basic bulbs which are much cheaper.

These are great while they last - but they don't last long. I bought these in February 2025 and as of July 2026, I'm having to replace the first one. They have an advertised lifespan of over 13 years and warranty of 3, but you can't do the warranty online, you have to either call or snail mail to take advantage of the warranty.

These work with touch lamps!

I bought these on Amazon after watching a review of LED light bulbs on YouTube. The Philips Ultra Definition bulbs where found to have the least flicker of the models tested in that YouTube video. This is a characteristic that I have sought in the LED light bulbs I have bought in recent years. In general, LED light bulbs have been disappointing to me because of the irritating flickering that happens when something in the house like the furnace blower, the air conditioner compressor, refrigerator, or even the dishwasher is running. The flickering happens particularly when a motor turns on or off. These light bulbs have not been effected by this phenomena and I have enjoyed that characteristic of them tremendously. Pros: - Does not flicker when a motor in my home turns on or off. - Bright light with a nice color temperature. - Dimmable. - Fits standard light sockets and in places where CFL lamps may not fit. Same dimensions as a standard incandescent light bulb. - Becomes slightly warm in operation, but not particularly so. Cons: - Not the most energy efficient, but still very good. - This 5000k light bulb might not be the best for a smaller bedroom, as it may be too intense.

No se si es un defecto o algo pero alumbran mucho menos que unos focos tecnolite de 8.5w, aun no instalo los apagadores graduables pero no creo que eso haga diferencia. Empiezo a pensar que no son Philips originales.

Lâmpadas excelentes, cumprem o que promete e chegou intactas funcionando perfeitamente. São laudas de vidro o qie mostra a qualidade do material

exactamente lo que necesitaba para mi estudio de pintura

Excelente produto. Não dá cintilação. Ótimo para quem faz leitura de livros, trabalha em escritório, grava vídeos em estúdio, fotografia. Lembrando que tem apenas 800 lumens e 8w. Ideal para usar em abajour, pequenos ambientes e em um conjunto de luminária. Caso queira mais forte, o ideal é pegar o modelo de 1500 lumens. O tom de cor dela é branca neutra. Usa vidro no bulbo. Philips acertou em cheio usando embalagem que suporta vibrações. IMPORTANTE: Para quem mora no Brasil, lembre-se esta é uma lampada MONOVOLT, ou seja, só funciona se sua cidade operar em "110" / 127v.
