That is one aspect I am glad to say is finally becoming less and less true now. I am talking about LEDs being pricier than other methods. Sure, some per-made fixtures are super expensive, but my LED light I made was actually cheaper than the MH setup I bought 3 years ago and it puts out more than 2x the light, so as far as "retro" I think LEDs are the cheapest lighting method, but just slightly in terms of up front cost, but TONS of saving in electricity. It is actually a little shocking, even to me, to see how few LEDs are actually required to match the output of a MH bulb. 24 LEDs, 50/50 white/royal blue puts out more light than a 250w MH or 6 T5HOs.I started looking into LEDs and so far they seem the way to go. They are pricier, but they generate way less electricity, no heat, no changing bulbs (for years)..
I haven't had any luck selling my MH lighting either. Something that would easily sell for 600$ last year isn't gaining anyone's interest at less than half the price.
I feel you on the selling of the MH.. I have 2 MH setups, a 400 and a 250 that no one wants. I even tried giving away the 400w locally and no one would even take it for free.
