GFA20A-12 or 20-watt LED driver Two models side by side: measurements taken by the author in their reviews, and their conclusions. The better value in each row is highlighted.
In brief: Based on review measurements: In test: GFA20A-12 (37 W vs. 19.65); Temperature rise: 20-watt LED driver (60 °C vs. 70).
Model GFA20A-12 SANMIM · 2019 Read review → 20-watt LED driver 2014 Read review → Voltage, V 12 40 Power, W 20 20 In test, W 37 19.65 Temperature rise, °C 70 60 Review conclusion Recommended Recommended
Only in one review: Current 1.7 A (GFA20A-12); Test current 2.6 A (GFA20A-12); Under load 37.08 V (20-watt LED driver); Ripple 35 mV (GFA20A-12); No load 0.2 W (GFA20A-12); Price 6.5 $ (GFA20A-12).
GFA20A-12: It handles 140% load, runs cool, and has low ripple; the author recommends it.
20-watt LED driver: The driver delivers up to 19.65 W with low ripple and normal heating, but its current is below the rated value.
Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
