VWV GY6.35 LED Light Bulb 5W AC/DC 12V Voltage is Applicable,50W Halogen Bulb Replacement .Non-Dimmable,White Light 6000K (Pack of 4) Please Look at The Description firstly and Then Purchase

I would rate these 4.5/5, due to one significant weakness (see below).What I like about them1. These bulbs produce more light than other LED or halogen bulbs I have tried.2. No ghosting. Some LED lights remain dimly lit in the "off" position, which is called ghosting. These lights have the proper circuitry to avoid that.3. No A/C flicker - Some LED lights turn on and off several times a second with the changing polarity of the A/C current. You can see that when you record a video, and you have rolling lines down the screen. These bulbs have the proper circuitry to avoid A/C flicker (ballast driver or capacitor).4. Great build - feels solid, no cheap plastics.5. Great packaging - comes with proper box and styrofoam holder to keep the bulb insulated from mechanical shocks in transit (see image).What I do not like1. Dimming flicker - With my Lutron Caseta dimmer, the lights begin to flicker when dimmed < 60%. This flicker is visible to the naked eye, but does not impact video recording like A/C flicker.2. No mention of CRI - which is a key indicator of light quality.

I used it to replace a 5 year old 60 watt halogen and it is maybe 20% brighter. Certainly not 40-60% as it claims.

Didnt work with my transformer

Bulb is bright. It dims correctly in my ceiling fan light fixture being controlled by my Lutron Caseta switch, but flickers below 30% dimming.

Did not work. Why did I buy something with no reviews
