Features:
Make sure the socket voltage should be the same as Gu10 lamp working voltage. If socket is DC voltage, Gu10 is 110-220V powered, Gu10 will NOT light on; You need remove the AC-DC transformer inside fixture.

Some MR16 working voltage is 12V AC/DC, while Gu10 is 110V AC; If there is a seperate MR16 transformer, Need REMOVE it.

PBT Housing Copper contact material
Physically change the contact,DON'T Change Voltage nor Current.

How to bypass the ballast?
1. Turn Off the Power.
2. Find the Ballast. Usually it is embeded inside the ceiling fixture. Pls pull off the existing PL lamp, reflector. Leave wire in junction box. and find the ballast.
3. Normally, the Ballast has a black and white wire on the input side (AC input side, 100V -120V for North America). It also has two red and two blue output wires. To bypass this ballast, please cut all the Input and output wires, so total 6 wires cut.
4. Then, you can connect the two red wires to the black wire.
5. Next, connect the two blue wires to the white wire. now ballast is bypassed
