GRV G4 Bi-pin 48-2835 SMD LED Light Bulb Super Bright Cool White AC/DC 12V-24V Pack of 6

The camper living room and kitchen is now lit up unbelievable. Really impressed how much it improved these areas. We love them. The only issue I have to look into, is when they are on, they affect TV and Radio station reception. Can someone offer a fix to prevent this?

I'm an amateur electronics tinkerer. A big part of my hobby is designing, 3D printing, and building LED powered lights, such as a 3D printed statue that lights up. Having used 3 mm and 5 mm LEDs for years, I'm discovering SMD LEDs such as the LEDs on these "light bulbs" put out a lot more light.Having nearly blinded myself with a "light bulb" similar to this, I hooked one of these up to my lab bench power supply and slowly added voltage and current. I stopped at 12 volts and had to hurry and grab some sunglasses, the bulb was shining so brightly. I can't imagine how overpoweringly bright these bulbs must be at 24 volts!!With power comes resp- I mean, heat. Leaving one of these bulbs sitting connected to the lab bench power supply with 12 volts, 195 milliamps running through it for a few minutes, the bulb got very warm, to the point that handling it was not painful but very uncomfortable. While someone that's buying this as a drop-in for say, a camper trailer interior light, may not have this issue, it's something to keep in mind for DIY purposes. I also can't imagine how hot these bulbs get at 24 volts either!For my DIY projects, I intend to run these LEDs between 5 volts to 12 volts- any higher, and I'll be machining light/lamp parts out of aluminum instead of 3D printing them. I'm confident heat from these bulbs won't actually melt the plastics commonly used in 3D printing, but I feel the bulbs get hot enough to soften and consequently warp the plastics.Since I've yet to dive into the galaxies of coding (i.e. Arduino projects) I appreciate the fact these bulbs have a simple two pin terminal layout. It makes connecting them to power much more simple. Finally, a note for any other DIY'ers that are perusing these bulbs: The polarity of the pins is not marked on the PCB. In my experience, when looking at the bulb with the LEDs facing you, the pin on the right is positive/hot and the pin on the left is negative/ground.

Great replacement for my under the cabinet kitchen lighting. These are a lot cooler (temperature wise) than the halogen bulbs. The color tone are slightly whiter than the halogens but after replacing all of them, it has a pretty nice warm tone..Update on Jan 2019: I've used these lights for 4 years now and still going strong. We do not turn off these lights and leave them on all day and night. I am impressed with this product.

easily replaced 20 watt halogen bulbs; longer lasting, cooler, equivalent light amount.

These bulbs were larger than I expected, but they did fit in the recessed rv lights. They are very bright which is what we needed.

First thing to know...these are quite large in diameter - about 1 1/2 inches - so they did not fit in any of my fixtures. I assumed they would be the size of the similar G8s I use - but they are double the size - so make sure you can accomodate such a large bulb. I could not test them, but they came nicely packaged and look to be of good quality.

Work amazing in our RV much brighter and the draw very little power and do not generate heat like the originals.

These look like very good quality bulbs. I thought these bulbs would fit in my landscape lights, but they are too large. This is my mistake.
