16.4ft(5m) Led Strip Light Natural White SMD 5050 4000K Non-Waterproof Flexible Natural White LED Strip Lights 300 LEDs/Roll LED Lights Strips Multifunctional LED Tape Lights

The light is bright, made well enough... just not 4000k, it's probably about 4500k. When trying to match other 4000k light it's not a handy description. If they listed it as 4500k would be 5 star.

These Kebinfen LEDs give an even white light with almost no variation between the different chips. They are not sealed with a waterproof cover. The double-sided adhesive tape is still not brilliant, but it is better than often found on these strips and this is the first set (from several different makes over recent years) where I have not needed to (all too easily) remove the original and supply my own d/s sticky tape. The full strip uses about 2.5Amps from 12.0Volts, rising to 3Amps at 12.3Volts, which is about half of the specified wattage (60W). As one might expect there is almost no power taken below about 7Volts and no light. However, if it gives out the correct amount of light for half the power I will not be complaining. I'm using a 5Amp power supply and my power leads are applied (soldered) to centre points on my two strips, for effectively four strips but only two leads going back to the splitter. The 4000K colour is a little bit cooler than a normal warm-white and does not have the undesirable pinkness sometimes associated with certain brands of LED bulbs. So it is ideal when arranged around a bathroom mirror for applying make-up, allowing for a result with a good compromise between indoor colour (3000K), outdoor colour (6500K), and industrial fluorescent lighting (often a greenish 4000K) As with all of these styles of LED lights, the strip is made up of half metre segments soldered together, and again this is the first where it has been done properly, so that the joins are almost unnoticeable and lie flat, without any distortion from unsightly great lumps of solder. The strip is 9.5mm wide so will fit nicely into a 10mm wide shallow U channel for good protection and heat-sinking. On a 12V supply the 150 Ohm dropper resistor for each trio of LEDs connected across the three chips (each six-pin SMD 5050 chip has three LEDs) is running at about 25 to 30 milliWatts. Safety. Be aware that not being waterproofed they should not be allowed to get wet, and with the exposed components easily touched by fingers the 12V supply should be double insulated from the mains or have the 0V side grounded to mains safety earth. I have stuck my strips to a smooth metal framework which fortunately happens to be bonded to mains earth, as well as serving as a heat-sink to maximise the LEDs lifespan.

Consegna nei tempi prestabiliti, confezionata dentro una busta di plastica con richiusura. Prodotto conforme alla descrizione e alle attese. Alla prima prova i led funzionano tutti e fanno un'ottima luce bianca. Per ora sono completamente soddisfatto, da valutare sarà la durata nel tempo. Dopo un paio di settimane dall'acquisto ho cominciato a farne un utilizzo vero e proprio, non solo prove; ne ho messe 5 strisce da 12 led in ognuna delle due plafoniere sul camper, al posto di due tubi neon da 11 w in ciascuna, nessun problema nel collegarle, ottima luce bianca e luminosità, sono molto soddisfatto. Visto alcune domande, aggiungo che l'alimentazione è considerata a parte; dipende dall'uso che uno ne vuol fare, sul camper si alimenta con i 12 V in corrente continua delle batterie di servizio, su un'auto o furgone si alimenta con la batteria usata normalmente per l'avviamento del motore, sempre a 12 V in corrente continua, se si vuole allacciare alla rete domestica occorre un alimentatore per trasformare la tensione di rete da 220 V in corrente alternata a 12 V in corrente continua.

Ruban led qui rend super bien, on doit être vraiment à 4000K donc couleur neutre. Pas facile à trouver donc je recommande ! (comme il n'est pas étanche, il faudra le placer dans un profilé led pour le protéger si besoin)

This is my second go with 5050 strips in Natural White color. I put these in an aluminum channel under cabinets. The adhesive on the LED strips seemed good to me, I had no issues with them coming off. I soldered wires onto the strips, which was simple and reliable. The LEDS match the natural white color of our other kitchen lighting. I didn't notice any unusual hot spots. Overall, I think this light strip is a good product, and a great value.
