• No. That is because: The 6” lights need more power. If 6” lights use with 4” junction box, under the insufficient power, the 6” light would not light up or it would just flicker.

• Yes! Our lights is damp-rated, but it cannot directly contact with water. You can use it in the bathroom, where water can not get through but moisture can exist.

There are several reasons.

• The wire falls off/ loosens/ breaks.
• The connector is missing or the connector lacks metal shrapnel.
• The voltage is too high.

To better find out the problem, you could do the following steps:

1. Double check the connection of the wire.
2. Double check the connector.
3. Install the lights on 110 volts.

There are several reasons.

1. The wire falls off/ loosens/ breaks.
2. You may not set the dimmer right.
3. You may mix the junction boxes (4” and 6”).
4. There are too many lights connected to the compatible dimmer.
5. Total brightness of the lights/house area: too small. That is to say, the number of lights is not enough.

To better find out the problem, you could do the following steps:

1. Double check the connection of the wire.
2. Double check the setting of dimmer.
3. Double check the Voltage, 9W for 4” and 12W for 6”.
4. Reduce the number of lights connected to the one dimmer. (Total Power of the Lights≤75% of the Rated Power of the Dimmer)
5. Install more lights. The recommended spacing for installation of 4” lights: 2-4ft (6” lights:5-7ft)

There are several reasons.

1. The wire falls off/ loosens/ breaks.
2. You may not set the dimmer right.
3. You may mix the junction boxes (4” and 6”).
4. You may use an incompatible dimmer.
5. There are too many lights connected to the compatible dimmer.
6. There are some high-power electrical appliances on the same circuit. (radio, air conditioners, refrigerators, etc.)

To better find out the problem, you could do the following steps:

1. Double check the connection of the wire.
2. Double check the setting.
3. Check the Voltage, 9W for 4” and 12W for 6”.
4. Select a dimmer from the recommended dimmer list (5 star).
5. Connect fewer lights to the one dimmer. (Total Power of the Lights≤75% of the Rated Power of the Dimmer)
6. Remove the high-power electrical appliances and set them further away from each other.

There are several reasons.

1. You may use an incompatible dimmer.
2. There are too many lights connected to the compatible dimmer.
3. You may use an incompatible circuit breaker.
4. There are some high-power electrical appliances on the same circuit. (radio, air conditioners, refrigerators, etc.)

To better find out the problem, you could do the following steps:

1. Select a more compatible dimmer from the recommended dimmer list (5 star).
2. Reduce the number of lights connected to the one dimmer. (Total Power of the Lights≤75% of the Rated Power of the Dimmer).
3. For the mechanical circuit breaker: you could replace a compatible dimmer.

For the electronic control circuit breaker: you could replace the circuit breaker first.

1. Remove the high-power electrical appliances and set them further away from each other.

Total Power of the Lights≤75% of the Rated Power of the Dimmer

If the rated power of the dimmer is 250W, the total power of the lights should less than 187.5W (250 W*75%).

If you install the 4’’ light(9W), you could connect 20 lights(187.5/9) to this dimmer at most. If you install the 6’’ light(12W), you could connect 15 lights(187.5/12) to this dimmer at most.

• The recommended installation spacing for the 6” light is between 5ft to 7ft. And the recommended installation spacing for the 4” light is between 2ft-4ft.

• The Operating Temperature: -20°C (-4°F) – 40°C (104°F).

No. The brightness of 2700k-6000k light is the same. They have the same lumen. That is to say, the brightness wouldn’t change if you change to another color. However, the 6’’ light is 1050LM, while the 4’’ light is 750LM.

“IC” stands for Insulation Contact. It means our lights can be in direct contact with insulation. But for blown-in attic insulation we suggest you could place metal between the box and the insulation or clog the box holes since there is a possibility that some material could get into the box and it could cause fire although the possibility is low. We do not recommend it.

They can be used on joists but there should be some other issues. Each light needs one junction box. There should be no sufficient room for a box on the floor joist. So you might need extension cord to wire the light and box. Also, our light adhere to the ceiling with clips. We do not recommend you use them on the joists but if you could overcome these and more obstacles, you could try our product.

• You could turn the wire out according to the original rotation direction, however, you can’t pull it out directly. And here is a video for you: https://youtu.be/y6Hx1h0GXik.

It means 3 color temperatures in one for your selectable. Compared with the single warm or daylight white recessed light on the market, our lights are 3 color temperature selectable, 3000k 4000k, and 5000k. Needn’t worry about what color temperature to buy, eliminates the hassle of returning due to inappropriate color temperature.

Yes! We suggest the wire should be AWG14-18. It is worth noting that the single-color connector is 2-pin, and the CCT connector is 3-pin. The pin size of our product is 1.5 mm. At the same time, our connector has been upgraded to make it safer and tighter, so you could see there is a little extra bulge on the connector.
