BMES 5Pcs 5W DC9-12V White High Power LED SMD Bead Chips Bulb Light Lamp

I really want to know from someone who is switching on these leds for a longer period, because I connected it for 1 minute and in that time itself, these bulbs have become exceedingly hot even after attaching it with heat sink. I really also want to know what will be the practical use for these leds and how one can use it for a longer periods without blowing it..About product, all the bulbs are working, too hot in one minute itself and you have to attach all of them to heat sinks inorder to operate it..Very reasonable price and that is why 4 stars..thank you.

We have purchased around 300 12V LED bulb and found performance satisfactory. Accessibility to reach manufacturer is difficult and we will expect that warranty clause will be honored.We have incorporated this item in our production line and requirement may exceed few thousands.

please only use with heat sink

I brought a oack of 5 for 129. Ie. Just 25 each for each.Used a 3.3 V and boosted it to 12V using a booster. It shines really Bright..!!😊👍

Not bright, too much heat. Should mount on a heat sink or aluminum sheet. Otherwise will burn out.

Some lights are not bright & some dead.Waist of time and money.Sellers jokes whith as.Good thing is refund was done.

Most of the items have a few defective LEDs.

Low quality product
