That's simply not true, HPS has a huge bump in IR, LEDs do not have ANY IR, and very little red light past 730nm (far red)everyone seems to have their own preference but the truth is that all lights grow plants.LED's produce about the same spectrum as HPS with less heat and higher cost. others prefer florescent or CMH bulbs for the higher UV and BLUE/VIOLET content which has been shown to increase THC and CBD content.we should all use what works best for us and ignore the critics who seem to have an almost religious affection for their lights.a cheap and easy DIY LED would be to use a couple of bridgelux EB strip lights bolted to a wooden frame and connected to a driver. no metal work involved just simple carpentry and soldering and as efficient as the best COB's. https://www.digikey.com/en/product-highlight/b/bridgelux/eb-series-modules?WT.srch=1&gclid=CjwKEAjwj6PKBRCAy9-07PeTtGgSJAC1P9xGkt8Johc-Ek5WSZhCIjcsnDAxqJidJd7eI0mxnCjCEhoCERjw_wcB in all honesty I'm a PU MMJ T5 closet growers but I have been doing small test grows with LED's for 3 years now starting with a mars hydro. then vero 18 and cree 3050 and currently with bridgelux EB strips. I have not seen the higher YPW that some claim and quality is higher if I supplement with a little UVA/UVB during flowering but LED's and HPS work fine for "street quality" products
HPS spectrum is vastly different from LED spectrum. They also produce light in two different ways. One is more similar to the way the sun makes light (the sun is a burning ball of gas) the other is it's own thing , passing a current through a semi conductor.
