led lighting

What would be the minimum strength led light to grow beginner corals ? I have a beamsworks led 76 light strip. 10000k, 400 lumens

It depends on the tank size. What size is your tank but to be honest I doubt that would grow anything.

It's a 20 gallon tall

Can you post a link to the fixture you have?

• Dimensions - 23.00” x 5.00” x 1.00”
• Brackets add 0.65" in height
• Includes 78 LEDs
• 400 Lumen
• Super energy efficient .06 watt LEDs
• 72x 10000K LEDs
• 6x Actinic 460nm LEDs

Being only 0.06 watts each they will not penetrate the water well and therefore not grow coral. If you want soft corals I'd try and get a fixture that has leds that are each at least 1 watt. 3 watt leds are better yet as they will penetrate the water further and grow most corals.

+1. Your fixture is not sufficient.

A good quality LED will produce about 120+ lumen per watt consumed. those are getting 57 lum per watt. Anything but efficient. Certainly won't support any corals.
