Frequently Asked Questions
Can the ELG-100-C350 be used to power a long series string of LED modules in a linear lighting fixture?
Yes. The ELG-100-C350 operates as a constant current driver at 350mA with a high output voltage compliance range of 143–286V, which allows a larger number of LEDs to be placed in series compared to lower-voltage constant current drivers. The total forward voltage of the series string must fall within the 143–286V range, and the number of LEDs in the string will depend on the individual LED's forward voltage. Total output power is 100.1W.
Is the ELG-100-C350 appropriate for driving LED street light or outdoor area light modules?
The ELG-100-C350 is rated IP67 waterproof and operates from -40°C to +90°C, making it suitable for use inside outdoor luminaire housings such as street lights or area lights. It accepts 100–305VAC input, covering both US and international supply voltages. Its high output voltage range of 143–286V at 350mA supports long LED series strings typical of outdoor area light engines.
Why would a designer choose 350mA constant current instead of a higher current driver for LED downlights?
Lower drive currents like 350mA result in lower LED junction temperatures, which extends LED lifespan and maintains lumen output over time — often called high-efficacy or long-life drive conditions. A 350mA driver also allows more LEDs to be placed in series within the same wattage budget, which can simplify thermal management. The ELG-100-C350 delivers up to 100.1W at this current level, supporting substantial LED loads.
How many LEDs can the ELG-100-C350 drive in a single series string?
The ELG-100-C350 supports an output voltage range of 143–286V at a constant 350mA. The number of LEDs in the series string is determined by summing their individual forward voltages until the total falls within the 143–286V compliance window. There is no single fixed LED count — it varies depending on the Vf of each LED used.
Can the ELG-100-C350 be installed in an outdoor LED fixture that may be submerged temporarily during flooding?
The ELG-100-C350 carries an IP67 rating, which certifies protection against temporary water immersion up to 1 meter for 30 minutes, as well as complete dust ingress protection. This makes it suitable for outdoor fixtures in locations prone to temporary flooding or heavy wash-down. For permanent submersion, a higher IP-rated enclosure would be required.
How does the ELG-100-C350 compare to the ELG-100-C1400 within the same product line?
Both the ELG-100-C350 and ELG-100-C1400 are constant current, ~100W LED drivers in the same physical enclosure (199×63×35.5mm) with IP67 ratings and identical input ranges. The ELG-100-C350 outputs 350mA across a 143–286V range, supporting longer LED series strings at lower current. The ELG-100-C1400 outputs 1400mA across a 35–72V range, better suited to shorter strings of higher-current LEDs. The choice depends on the LED module's rated current and string voltage.
