greenandco® CRI 90+ Step dimmable LED spot Replaces 39W GU10 Halogen Spotlight, 5W 320 lm 3000K Warm White 110° 230V, no Flicker, dimmable Without dimmer, 10-Pack

As we are turning towards more energy-efficient processes and products to save energy and consequently natural resources it slowly trickles to our households. These bulbs are quite bright at 420 lumens but it is not in the 50-watt halogen range since they produce from 500 to 700 lumens, so the 50-watt equivalent claim aims for the lower number.They are warm white so they are suitable for the bedrooms, living rooms and any comfortable areas as the 3000K feels warm and comforting so I would avoid putting them in general areas such as kitchens and bathrooms where more sterile light is better.They have an interesting feature where the dimming can be achieved by turning the bulb on and off in sequence to achieve 100%, 50% and 20% of brightness which is quite novel and useful as you do not have to install a dimmer switch.The claimed 25,000 hours of service life sounds about right for good quality LEDs, however, it would be nice if the bulbs had some warranty on them.The bulbs are quality made and have no strobing effect, it is great that they have CE certificate so they are safe to use, the outer materials are glass and ceramic so no exposed metal except for the copper leads.Overall, for the price of £3.20 per bulb, they are a bit costly but there is no need to install a dimmer switch which can be tedious or too inconvenient for some. I would recommend these bulbs as they are energy efficient and quality made and should last for a while.

I have installed quite a lot of GU10s (about 120 to be exact) but this is the first set I have had that can be dimmed by switching on and off. That is quite an advantage, because I have had to buy new dimmer switches on quite a few occassions, which are not cheap. These have three levels of dimming - right down to 20% as well as a 50% setting. It works well and these being fairly warm 3000K bulbs lends themselves to being used as softer more ambient lighting. All this for no more than the usual cost of led GU10s. If you are still running halogen because you want to have a dimmer then these are a great solution (although you will need a straight on/off switch - or if you have a dimmer with a click on/off these should work as long as you have it turned up to full power). Highly recommended.

Most of the bulbs in my house are dimmable and I've never had any problems since I've used well-known brands which may cost a bit more but are reliable and last a very long time.This pack of 5 bulbs costs £15.99 so works out to be around £3.20 per bulb.In terms of brightness, it is very bright and easily lights up the room. As I have dimmer switches in all of the rooms, it makes it easy to do so compared to those who have to keep switching the light on and off.It's a warm-ish colour, it's certainly more brighter than the other bulbs I have used but not as warm as them.The only issue I've noticed at times is when dimming it to a low brightness, the bulbs will all flicker or turn off for a few seconds before settling on the low brightness.It says the life span is 25,000 hours based on 3 hours of use per day but I highly doubt this will come anywhere near that. Only time will tell how long these will actually last.If this was helpful, please tap that helpful button below - Cheers!

I absolutely love every thing about these lights, they are so versatile. I will outline the reason why I think they are a good product.They are energy saving and could last up to 22 years if left on for approx 3 hours today.Great for the environment or what.They are dimmable at 3 stages ( high bright, mid bright and low)20,50& 100% The lights are also energy efficient A which is marvellous and given how long they could last well worth the £16.00You don’t have to instal dimmer switches to dim the lights if you don’t want to as you can use you’re standard on if light switch.The bulbs have a CE mark so they are safe which is reassuring.Great lights and worth buying.If you found this review helpful please click below thank you.

DISAPPOINTED AS THESE GU10 SPOTS ARE NOT DIMMABLE YET THEY SAY THEY ARE

Super rapide, comme d'habitude

Rispondono Pienamente alle caratteristiche tecniche indicate, ottima luminosità e cono di luce ampio

Honestamente, no sabía que estaban haciendo luces LED "auto-regulables", digamos, es decir que no necesitan un regulador o "dimmer" instalado ni una conexión Bluetooth con un app en tu móvil para poder graduarse en términos de intensidad. Sencillamente, accionas el interruptor varias veces seguidas para ir bajando la intensidad de la luz y, para regresar a la intensidad más alta, dejas apagado unos segundos y vuelves a prendes—más fácil imposible!Efectivamente te quita la necesidad de tener que instalar un regulador, lo cual es excelente, sobre todo si eres inquilino, sabes? (Además que no todas las bombillas LED y ahorradoras son compatibles con los reguladores, dicho sea de paso.)Ya por eso me parece que es un producto que vale la pena. Pero no es lo único que tiene de bueno.Claro, al ser LED ahorra mucho en energía, ya que solo consume 5W pero produce luz a una intensidad equivalente a 50W incandescente.Pero lo que a mí más me gusta—aparte de lo además "auto-regulable"—es que tiene un IRC de 90+. El IRC es el Índice de Reproducción de Cromática. Brevemente: Esta medida califica las fuentes de luz por cuán fielmente reproducen los colores de la realidad, es decir, aquellos que se consiguen bajo luz natural (también conocida como el sol). Mientras más alto y cercano a 100 sea el IRC, mejores serán los colores. Una luz con un IRC bajo da a las cosas esa apariencia de otro mundo que a veces a uno le da dolor de cabeza—o que en fotografía hace que los colores queden como si se hubiera pasado todo por un baño de ácido o 1.500 veces en la lavadora... En términos generales, para obtener unos colores decentes, sobre todo en foto y vídeo, se necesita un IRC de, al menos, 90—y en lo que a mí respecta, como profesional, si es menor a 93, ya no lo uso profesionalmente. Pero para un uso en casa, 90+ está muy bien. De modo que el hecho en sí que el fabricante mencione el IRC me parece un plus, ya que normalmente no dicen nada, y eso suele ser porque los LED usados son pésimos y tienen un IRC de menos de 75! Y todo en tu casa parece lo que ve alguien que ha tomado ácido... tu piel medio verdosa y desagradable... en fin, todo muy desagradable y cansino.Finalmente, la otra cosa que me ha gustado mucho es que tiene una temperatura color 3.000ºK, lo cual las hace verdaderamente cálidas, incluso un poco más cálidas que el "blanco cálido" tradicional. Sin ir muy en detalle, la temperatura color mide el color de una fuente lumínica en grados Kelvin; y en iluminación nos sirve, grosso modo, para medir cuán cálida o fría es dicha luz, o, mejor dicho, cuán similar es la luz del sol o a la luz artificial de tungsteno (que era el estándar lumínico antes de que existieran los LED). El tungsteno es el metal que se usa en los filamentos de las bombillas de antes (o esas de tipo vintage que ahora están de moda) y que generan una luz artificial más tirada hacia el naranja. El tungsteno tiene una temperatura color de unos 3.200ºK. En contraste, la luz que emite una vela, que es mucho más naranja (es decir que tiene menos azul y más rojo), mide 2.000ºK. Estas luces, es decir, las que están por debajo de 4.800ºK se consideran tradicionalmente como luces cálidas. En el otro extremo de la escala está la luz del sol que mide normalmente unos 5.700ºK. La luz fría tradicionalmente comienza a partir de los 4.800ºK para arriba. (El flash fotográfico, por ejemplo, está entre 5.000-5.500ºK.) De modo que una luz de 3.000ºK da calidez muy hogareña.

Ampoule led 3 step de luminosités couleur jaune

✅PRO:– Temperatura 3000K ideale– Buona realizzazione dell’attacco GU10– Buona luminosità– Non sfarfallano né flickerano se si fanno foto o video.❌CONTRO:– Si surriscaldano molto– Ce ne sono di pari prezzo con CRI > 95+ (migliore resa cromatica)– Piuttosto pesanti– Un po’ troppo costosiA seguire la recensione completa:📦SPEDIZIONE E PACKAGING:Nella scatola si trovano 5 faresti GU10, ciascuno confezionato singolarmente.📲FUNZIONALITA’ E DETTAGLI:La prima impressione è di un prodotto di ottima qualità costruttiva, molto solido. Si sente piuttosto pesante in mano a livello della testa, che sembra essere in vetro esternamente. I contatti a vista sembrano ben realizzati, così come l’attacco inferiore.I furetti hanno attacco GU10, quindi quello con i due piedini più grossi e circolari. Sono faresti da 5W, che emettono una luce bianca calda a 3000K con intensità luminosa di 420 lumen, dimmerabile su tre livelli: 20%, 50% e 100% di intensità. Anche per chi ha un dimmer in continuità e non a livelli comunque risponde bene.Il furetto ha un indice di resa cromatica (CRI) maggiore di 90 e devo dire che in effetti non altera la percezione dei colori nella stanza.Le dimensioni sono quelle di un classico faremo, forse un po’ meno ingombrante nella parte sporgente. 50mm di diametro massimo e lungo 57mm, si adatta bene ai lampadari a faretti che ho in casa.Non contengono mercurio.Come durata mi sembrano essere abbastanza resistenti e sono garantiti per circa 25 000 ore. Come intensità luminosa ad occhio confermo i 400 lumen, di un bianco caldo ma non eccessivamente giallo.Il fascio luminoso è abbastanza indirizzato, infatti l’angolo di illuminazione è di 110°.Classe energetica A+, azionabili con la classica tensione casalinga 210-230V a 50-60Hz.Fra i difetti riporto il peso elevato della porzione in vetro anteriore, che soprattutto in lampade che portano i faretti rivolti verso il basso risultano un po’ scomodi.L’altro difetto è che non posseggono una delle moderne testine sagomate per disperdere il calore, e si surriscaldano molto facilmente. Per ora anche in usi continuativi (circa 12 ore) il surriscaldamento sembra non aver fatto danni, però scottano davvero!💸PREZZO:5 faretti a 22,99€ sono un po’ troppo costosi: circa 4,60€ cadauno quando sul mercato si trovano a prezzi inferiori.⚖️VOTI e conclusioni:Durabilità nel tempo: 3/5Qualità dei materiali: 4/5Capacità di svolgere la funzione: 4/5Lo consiglierei: 3/53.5 approssimato a 4 perché il peso e la superficie in vetro potrebbero rivelarsi più durevoli del previstoGrazie per la lettura! Buoni acquisti!
