LM-U270A
1. Products and Application
This specification defines general specification and performance for LM-U270A LED module.
Samsung Linear Modules target to replace conventional fluorescent lamps as T5, T8 and so on
with LED solutions. Due to transferring LED, new luminaire transferred to LED can take more
energy saving and longer life-time.
In special, Samsung has competitiveness in middle-power solutions. All of Linear modules use
2323(MP23L) that had been passed LM80. Middle power solutions provide more homogeneous
and higher efficient lights. Linear module has been designed to expand length simply and adopt
easy connection way.
LM-U270A has paired module as LM-U039A for small room. When you design luminaire using
LM-U270A, sometimes you can't cover your whole fixture. For that case, Samsung provides
small LED module (LM-U039A).
This specification describes only LED module but Samsung doesn't provide own driver.

7. Precautions In Handling
1) LED Lighting for white light are devices which are materialized by combining white LEDs.
The color of white light can differ alittle unusually to diffuser plate(sign-board panel).
2) Handling
-Don’t drop the unit and don’t give the unit any shocks.
-Don’t storage the Module in adusty place or room.
-Don’t take the unit to pieces.
3) Cleaning
-This LED Module should not be used in any type of fluid such as oil, organic solvent, etc.
-It is recommended that IPA(Isopropyl Alcohol) be used as asolvent for cleaning the LED
Module.
-When using other solvents, it should be confirmed beforehand whether the solvents will
dissolve the package and the resin or not. Freon solvents should not be used to clean
the LEDs because of worldwide regulations. Do not clean the LED Module by the ultrasonic.
-Before cleaning, apre-test should be done to confirm whether any damage to the LED
Lighting will occur.
4) Static Electricity
-Static electricity or surge voltage damages the LED Lighting.
5) Others
-If over voltage which exceeds the absolute maximum rating is applied to LED Lighting,
it will cause damage Circuits(that LED is included) and result in destruction.
-Do not directly look into lighted LED with naked eyes for long time.
-Please use this product within 5months, which is kept in its original packaging unopened
when stocked.
Samsung-LED may make changes to specifications and product descriptions at any time,
without notice.
