Don't kid yourself, SF4000 is a choice if on a budget. It's not the SAME as an HLG light........binned diodes that HLG rejects are bought up by budget companies. Either buy HLG quantum boards and DIY the light or buy an HLG.Sf4000 spider grower same as hlg and alot cheaper uses samsung leds lm301bs awsome light
