Frequently Asked Questions
Can I use the LDD-1200LW for a constant current LED downlight?
Yes, if the downlight requires a constant current driver at 1200mA and the LED load falls within the 2-30V constant current range. This is a 36W step-down constant current driver, so it is intended for LED loads powered from a higher input source within the 6-36VAC input range. It is not meant for constant voltage LED products.
Is the LDD-1200LW a good fit for small LED arrays in compact fixtures?
It can be a good fit for small LED arrays when the array is specified for 1200mA constant current and its forward-voltage total stays between 2V and 30V. The compact 31.8 × 20.3 × 12.2 mm size helps in space-constrained assemblies. Because it is a step-down driver, the input source must also stay within the 6-36VAC range.
Can the LDD-1200LW power waterproof signage or outdoor LED modules?
It can be used in wet or outdoor equipment when the LED module is a 1200mA constant current load within the 2-30V CC range. The driver itself is rated IP67 Waterproof, which supports use in harsh environments. It still must be matched to constant current modules rather than constant voltage signage products.
How do I check LED compatibility with the LDD-1200LW?
Your LED load must require 1200mA constant current and have a total forward-voltage requirement within the 2-30V CC output range. The number of LEDs depends on the forward voltage of each LED, so there is no single fixed LED count for this model. If the load is designed for constant voltage instead, this driver is not the correct type.
What are the main differences between the LDD-1200LW and related LDD siblings?
Within the low-voltage waterproof wire-style group, LDD-1000LW is 1000mA, 2-30V, 30W; LDD-1200LW is 1200mA, 2-30V, 36W; and LDD-1500LW is 1500mA, 2-30V, 45W. Higher-voltage H and HW versions extend to ranges such as 2-46V or 2-52V with higher power ratings, while LS versions in the same family use lower maximum CC ranges like 2-28V. Model selection mainly comes down to required output current, CC voltage range, and power.
Is the LDD-1200LW suitable for cold or hot outdoor conditions?
Yes, its operating temperature range is -40°C to +85°C and the housing is rated IP67 Waterproof. That makes it appropriate for demanding temperature and moisture conditions when the rest of the system is designed around the same limits. The 3-year warranty and CE/EAC certifications are also part of the listed product specs.
