I have a single Giezemann Pulzar "Planted" LED light bar that stretches across the full 5' width of the 500L, it was comparatively expensive at the time, 5yrs ago. But costs pennies to run, per week and is supposed to have a 10,000hr lifespan. At the time I was very limited in choice for a light bar of this length. The alternatives were tubes, but they are considerably more expensive to power and 'should' be replaced yearly. If it were to fail tomorrow I would replace it with another LED light bar. Definitely not tubes.

A single bar is enough for the quite undemanding plants in this unheated tank. Particularly as its positioned so it gets up to a maximum 4 hours of sunlight in the mornings.

Only downside of that is the weekly algae glass scrape, but the fish consume it with gusto.

I use Chihiros on the smaller tanks (30litres) and a Twinstar on one of the 200litre tanks that are open top.

The other tanks use just lights that came with them with the exception of the Fluval Roma which has a Fluval Plant 2.0 but that has a hood.

I just bought a Nicrew 24/7 Planted Tank LED light bar - waiting for it to arrive.

https://www.amazon.co.uk/gp/product/B07Q...UTF8&psc=1

I bought this because of some reasonable reviews on yootoob and Amazon, and also because I like the timer for the lights. I'm thinking that if it doesn't give enough light at depth I'll back it up with another light bar just set to come on at full daylight times using an external timer.

And now, I'm significantly less nervous - my LED unit arrived early courtesy of Amazon - a pleasant surprise for a Sunday.

I've done a mini-writeup within in my tank build thread, here - I hope you find it useful.

Haha! The earlier models only had a rocker type switch to turn on/off which broke over time and shorted out, ending up with melted wires or/and switches. It certainly will be interesting to see how you get on with the newer generation light!
