Wow ok this topic has blown up more then i would expact![emoji6]
The case is, i started planning for this hobby round '11. Back then diy leds where a very populair part of the hobby. I have a some what complete setup laying around since then.
But the thing is, much has changed since then! My original tank plan( i got a bigger one then i had planned the leds for) also i had made a controller using arduino ( acording to a step by step tutorial) and still have'nt programed it..
The setup i have is;
4 CREE xm-l (2 cool 2 neutral whites) on meanwell eln-30-12p
8 CREE xp-e (6 royal 2 blues)on meanwell eln30-24p
And a bunch of uvs reds and greens on a cheap aquastyle driver for 7-12 leds..
But i have no idea If it will be enough for my 50X50X55 cm tank and be able to keep sps..
Also i have been looking at of the shelf fixtures and their features.
For example those Ai hydra 26 HD's for around 400 backs (€) thats like 250-300 retail..
Im leaning to get a nice second hand one
My current favorite is the BlueAcro Mega4Z 20K Pro Blue https://blueacro.com/acrostar/ with 4 x 80W T5 supplementation on my new 150g.
