Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE". For DA-Type, Constant Current region is 60%~100% of maximum voltage under rated power delivery.
3. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
4. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
5. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
6. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
7. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
8. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
9. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
10. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

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 with a case temperature (Tcase) range of -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 indicates protection against temporary water immersion 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.
