Installation of the light fixture/lamps in a direction other than specified can cause overheating, deformation, insulation failure and falling of the light globe. It also results in a contact failure at the socket of the LED module/unit, and causes lighting failure.・ Make sure that the light fixture is not too close to the ceiling surface. If the light fixture is installed too close to the ceiling surface, the light globe may not be able to be removed, thus disallowing replacement of the lamp. In addition, convection of heated air can cause a dark stain on the ceiling surface.・ Make sure that the mounting surface is strong enough to hold the light fixture. If the strength of the mounting surface is not strong enough or if the light fixture is installed in a method other than specified, the light fixture may fall and the ceiling/wall surface may become bent or damaged. Reinforce the mounting surface or install the light fixture at a location with reinforcement. [Note 3] If the light fixture is installed to a soft ceiling such as a rockwool ceiling, the ceiling material may become damaged, and a gap may be created between the frame and ceiling surface.・ Do not embed the light fixture for general outdoor use into the ceiling.Select the light fixture suitable for the place of use. Never attampt to modify the light fixture.When connecting the power cable to the power supply terminals of the light fixture, ensure firm and secure connection. Loose connection can lead to a fire or electric shock. ［Note 4］・ In the case of screw-type terminals, tighten the screws tightly. Remove the cable sheath in the length indicated on the parts.In the case of feed wiring, connect cables of the same wire diameter to the screw-type terminals.If the wire diameters differ, connection failure can occur in the thinner wire and cause excessive heating.space of 10 cm or more between them.[Note 3]Indoor Wiring Regulations 3205-3: When installing a light fixture, reinforce the structural material or use a wooden reinforcement or outlet box in order to ensure that the mounting surface is strong enough to support the weight of the light fixture.* Do not mount the light fixture directly to a resin outlet box.・ Do not install the light fixture in a place where the heat resistance of interior material is only up to 90°C or lower, such as vinyl wallpaper. Otherwise, the wallpaper can become scorched and discolors.・ If the light fixture is installed to a ceiling or wall immediately after the pasting of wallpaper, adhesive can damage the plated or coated surface of the light fixture. Install the light fixture after the adhesive dries sufficiently.・ When installing the light fixture directly to a concrete surface, install the light fixture after the concrete dries sufficiently. （Be sure to take the construction schedule into consideration）. If the concrete is not dry, the light fixture can absorb moisture from the concrete, and the insulation can deteriorate. In addition, alkali components in the absorbed moisture can damage the coating of the light fixture and cause it to peel off.・ In the case of the moisture-proof or rainproof light fixture, make sure that the rubber packing firmly contacts the mounting surfaces of the wall and light fixture. If the mounting surface is irregular（such as a tiled surface）, be sure to fill the gap around the mounting section of the light fixture with a caulking agent. Also, ensure that water will not enter the power cable routing hole in the light fixture.* For the installation of light fixtures for outdoor use, it is recommended to use rust-resistant wood screws such as stainless steel screws.caution can result in a fire, electrical leakage or shortening of the service life of lamps. 1.
