used 400w+ full spec LED for veg, now in 4th week flower, all looks good, waiting for buds to swell up nice and fat. Possible to switch to 600 hps for last 4 weeks? Does it matter now? benefit or not? ---

You shouldn’t have a problem switching, but the question is whether or not the HPS will deliver more PPF and/or better spectrum than your current lighting. Tell us more about your ~400w LED. ---

In the words of the TOOL TIME TIM ALLEN (aka Tim Taylor) MORE POWER is good. ---

> [@merlin44](#): > > how much of that additional power Great point. A lot of the wattage an HPS consumes goes toward generating heat rather than light. ---

If I can burn 20% more fuel in my skidoo and get 10% more HP I will do it. Provided I can afford the fuel and my engine don’t overheat. I don’t care how much waste is goin out the pipe. To each his own ---

> [@BriscoDarlin](#): > > with the LED My first year with LED lights. Actually my first year in forty, since 1000HPS, was awesome. Can we reset the FLUX-CAPACITOR? HPS was warm all winter and cured bud in a day for smoking. Fall harvest was ok but currently I am having trouble heating tents during winter and HPS would fix that problem. Next winter maybe. ---

> [@BriscoDarlin](#): > > continue with the LED Probably a good choice. LEDs are 70 - 90% efficient while HPS is only about 40% efficient (watts to PAR). A general estimate would be that you would need to run a 600 watt HPS to achieve the results of a quality 400 watt LED fixture, give or take. ---

@dbrn32 Thoughts on the Ledestar 302h diodes? They look pretty capable to me, but I’d not heard of them until today. ![Ledestar Diodes](https://global.discourse-cdn.com/growingmarijuana/original/4X/5/9/0/590c9d3abe3317bd30e71085467b0b4ecce78bd5.jpeg) ---

I haven’t heard of them either. My guess is they’re stretching truth on performance of their leds.
