Power Supplies For Your Solstrip UK LED’s
Once you’ve chosen your LED lamp design, calculated your coverage needs, and chosen your color spectrum, the next step is to decide which power supply or driver you need to power your light.
The truth is there are many possible options for your choice of driver depending on the number of strips per circuit, and the type and design of your circuits. But the mission of Solstrips UK is to bring simplicity to LED DIY, so based on a parallel-wired system, these are our basic driver suggestions:
•5 SolStrips (SunMini): CLG-150H-24A
• 10 SolStrips: (SunMidi): HLG-320H-24A
• 20 SolStrips (SunMaxi): 2 x HLG-320H-24A
We highly recommend getting the lower powered driver over a higher power alternative. The physics of LED chips make them most efficient at about 70% of their rated max, or about 33-36 watts for SolStrip X2s. You can drive them at 100% if you want, presuming you keep them cooled within their operating range (aim for 50-60C max). But you will get less than 15% more light for expending 30% more electricity.
That means you’ll end up dimming the driver even to operate the strips at 100% of their rated power.
Basic LED DIY system rule: Run your LEDs soft; and your drivers hard
Running your strips at around 70% by using a driver which has a maximum output slightly below the total maximum rating of the SolStrip circuit (using 50w X number of strips) makes for the most efficient and cost-effective use of both the SolStrips and the driver. The LEDs are most efficient at around 60-70% of their max output, and the drivers are most efficient when run at 100% of their max output.
LEDs aren’t like HID bulbs, which are optimized to run only at their maximum rated power. LEDs are more like cars, able to operate across a range of output, with a maximum and minimum wattage, and an efficiency sweet spot somewhere in-between. Aim for the sweet-spot when selecting your driver, not the maximum. You’ll save money and be more satisfied with your results.
