ZETLIGHT E3-M Marine Nano LED Lamp (24W)

Description

ZETLIGHT E3-M Marine Nano led lamp (24W)
Zetlight E3 24W LED Light encourage growth of saltwater coral. Fin-shaped heatsink structure improves cooling performance and evenly spreads heat which increases LED lifespan. Light can be controller with rotary dimmer which the brightness can be adjusted.

Suitable for marine water. Effectively encourages growth and coloration.
24W high brightness LED: 28 LEDs, White: 6000-7000K, Violet: 410-415nm, Blue: 460-465nm
Recommended for tanks with width between 30 and 45cm.
Efficient Heatsink: effective cooling ensures LED lifespan, fin-shaped heatsink structure improves cooling performance and evenly spreads heat which increases LED lifespan
Rotary Dimmer: Simple and effective way to adjust brightness for your aquarium.

Running the ZETLIGHT E3-M Marine Nano LED over an SG reef cube

We see this 24W nano fixture paired most often with 30 to 45cm all-in-one cubes, exactly the footprint that fits an HDB study nook or a kitchen counter without overwhelming the room. The compact fin heatsink matters here because our 27 to 29C ambient runs warm year-round, and a fixture that sheds heat passively avoids dumping extra watts of warmth into a small saltwater volume that already fights to stay stable.

For soft corals and easier LPS, the rotary dimmer lets you ramp brightness slowly over the first weeks rather than blasting fresh frags. We usually suggest mounting it a little higher at first, then closing the gap as colonies acclimate. On a nano this small, a single E3-M typically covers one well-placed colony zone rather than a sprawling garden, so plan your rockwork around the beam spread before you glue anything down.
