I just posted a step-by-step assembly of super easy DIY LED, which I have done about a year ago. 1 year is a long time in the progress of LED technology, but Philips XF-3535L is still great in terms of efficiency. The price came down a little bit over the year, but COB (chip-on-board) LEDs (such as Cree CXB series and Bridgelux Vero) are still cheaper. But there are lots of positives about XF-3535L.
I mostly use it for orchids, but it can achieve fairly high light for CP if you use lots of them. So it may be useful for some of you.
