Theoretically, our products are safe for children over 4 years old. However, because some of our parts are very small, it may be difficult for children to connect. Therefore, it is recommended that children over 7 years old or need adult supervision.

All our lights are green LED lights, which produce very low heat. Our products are designed for continuous operation.Power box will have slight heating due to long-term use

While LEDs are designed to last for a very long time (rated life of up to 50,000 hours and over), extra care must be taken to ensure they are well looked after and powered correctly. Aside from powering using our 4.5-5V battery packs, our LEDs can be powered using mains power via our USB power cables connected to the correct power adaptor.

Our components all run on a very low voltage of 5V, so it is essential to use appropriate power adaptors.

If choosing to power our lights using mains power, it is important to only use the Light My Bricks Universal Power Adaptor. We do not recommend our customers using other USB wall adaptors on the market as it will run the risk of damaging the LEDs overtime (LEDs may go dim) and this is not covered under our  warranty. Electronic spikes can dramatically shorten the life of our LEDs and can also result in them burning out or becoming very dim. Using an incorrect power adaptor will void the warranty of your product.

Another important thing to note when powering our lights over mains power is to give the lights rest. Like any type of light or LED, powering them 24 hours a day, 7 days a week will also shorten the life of them. If you wish to run them all day, it is beneficial to give them a rest each day by powering the mains power completely off.

We provide a cost-effective product by reading a large number of products, comparing and analyzing their relevant comments, as well as relevant configurations and suppliers.

We're constantly releasing new sets to update our ever growing list of lighting kits. But if you don't see your need, you can recommend it to us on our"Chat" in the lower right corner, or email us.Anotheris MOC products that Lego has not yet provided.These are carefully selected high-quality products, so we can occasionally change our perspective and thinking to increase playability and variousness.And the price of this kind of products has more advantages. Of course,I don't reserve it, there will be some differences in product quality and touch with LEGO.

We offer multiple lighting options. Battery powered using either standard AA batteries or using flat CR2032 batteries. You also can use USB power cables which can be plugged into a USB power bank to power up lights.

All of our lighting products run on less than 5 volts, unless otherwise specified in the introduction.

Some products use special accessories. Please refer to PRODUCT INFORMATION on product page, or refer to Instruction.

All our lights are green LED lights, which produce very low heat. Our products are designed for continuous operation.

Power box will have slight heating due to long-term use.

The running time for our light kits depends on the power type and the number of lights connected. More connected will run as short as compared to a kit with fewer lights. As time goes on, the lights will slowly become dimmer as the batteries grow weaker.

Our USB option, can run as long as the USB power bank allows or even continuous if connected to a USB Adaptor that plugs into a power main.

As a example, the GHOST BUSTERS ECTO-1 #10274 (18-Lights + Flat Battery Pack) will run for approximately 4 hours before dimming and then eventually stop after 8 hours.

AA Battery Packs last longer than Flat/Round Battery Packs

Yes, of course! This is one of Light Kits features.We offer multi-light kit connecting kits which allow you to connect up to 4 light kits and power them using a USB Power Cable to a USB Power Bank or USB Power Adaptor that can connect to power main.Simply swap out the battery packs with connecting cables. Then connect the connecting cables to an expansion board. Next, connect the expansion board to a USB Power Cable and select your power source (Power Bank or Power Adaptor).

Although there are no limitations to how many lights you wish to power off a single source, we recommend using around 8 light kits per single power source. This will provide you with optimal brightness from your lights.

The more lights added to a single power source will result in a decrease in the level of brightness. This is because of the increased power required to illuminate the lights.
