Have this light on my 35l Scaper's tank and the light is very pleasant and not as cold as in cold-white LED lights. Plants continue to grow well although not all corners are excessively lit in the basin. The design is unbeatable and very appealing and high quality. No cheap-looking plastic or aluminum bracket lamp above the pool. Unfortunately, the price in Germany is outrageously high, so I have to deduct a star! Elsewhere in Europe, you get the light of 75. There I ordered two more copies for my peel's Tank 50l Scaper the Daytime cluster lighting.
