When it comes to lights, specifically LED lights. Manufacturers make the difference. Without being overly complicated, you need a high end company to get the best light. Not all LED chips are made equally. When the chips are made they are tested and ranked by how much light intensity they produce. Specific companys have contract with the manufacturer to get the top bin diodes. They pay more for them, therefore you pay more. The difference between top bin and 2nd best can be as much as 10%. That’s a massive amount when added up over the whole light fixture. There are only so many top bin diodes manufactured at a time, so companys like HLG, California Light works etc have those top bin diodes almost exclusively, there are some others, but not too many. Then you have the secondary bin diodes, companys like spider farmer, mars, vivaspectra etc. These are great lights, especially when the price is taken into consideration. This is where most people start, fo good reason.
We havent even touched on the temperature of the light (Kelvin rating), PAR/PPAR values, heat by product, spectrum, cost of running, or efficiency at various running temperatures. All those are considerations to be taken into account.
Lighting is an area that will always be intimidating. Theres so much important information to be learned and new concepts that are difficult to understand. And a whole lot of MATH, which is kinda universally hated.
