Only 35.. That means I started when you were 5. I would never go back to MH bulbs. You may be old enough to remember when TVs looked like they were carved out of a block of wood. Lol. Even though they may still work today would you rather have a 4k big screen or that? That's how I look at modern lighting but as I like to say whatever helps you sleep at night. They still work fine but they have their own faults as well. My biggest challenge was trying not to boil everything in my tank. Lol
Absolutely terrible analogy. Did the halides show your tank in black and white 144p? And now your LEDs show 4k HDR10+? That's the only way your analogy makes sense
