lighting

Hi, I have a 50 litre sump with a section as a refugium, the problem is that I have a Juwel Vision cabinet and this means that I have a long quite thin sump (30cm wide, 50cm long, 50 cm high.) I currently have a 25w CF bulb (2700k) lighting it but I am worried about heat that the bulb gives off...

So I was talking about it the other day, and ordered some of the SMD5050 LED light modules, and although they are no where near the high powered LED lights, they are a good DIY light that seem to run at fairly low heat, will grow low light plants very easily, and are great mostly for aesthetics...

Hiya folks, I'm looking for some opinions, advice on replacing my Juwel 180 92cm T8 bulb lid lights. They've literally died on me today. I've tried new spare bulbs, fuses and the switch and nothing. So I want to change up to something better.   Has anyone got any good LED or T5 replacement...

I was all set to switch a Rio 180 from T5's to LED. But in doing do I found this article stating they're not good enough. The same shop also has a later article saying that one particular unit from Arcadia is now good enough, and they only sell that.   I know this article is now quite old, but...

Ok, setting up my first aquarium - 37 gallon.  One thing I'm confused on, though the right answer is probably simple.  Its about how much, and when, the LED lights should be on.  In other words, while it will never be in direct sunlight, there will be plenty of light around the aquarium in...

Alright so I've seen some people doing their own DIY light fixtures using CFL bulbs for their aquariums. I was thinking I would try this since it's super cheap and I am also cheap so I'm not about to spend a ton of money on lighting. I'm new to all of this so of course I bought tons of...

  I built an LED/RGB Canopy and light system for my cichlid tank. Here's a a YOUTUBE video.   I made a 1 minute cross fade from moonlight to daylight. Then to show just how subtle it was there is a 3 second "sunset. I am about to build my big tank. 120 long. I will be making a canopy and...

Ok, so I have a 222litre tank on the way (possibly ready for collection this weekend). However the whole set-up (it's a vivarium and aquarium stand) is slowly reaching my budget. Thereby I need to begin to cut corners for now. Don't worry, the heater and filter etc. has not been scrimped on...

I just got a 5 gallon tank. It's not set up yet, but it's going to be an Iwagumi style shrimp and mosquito rasbora tank. I'm hoping to get dwarf baby tears and maybe some dwarf hair grass for the tank. I'm also going to have a CO2 system. I have a 2w LED light, but is that going to be good...
