Led lighting modification?

So I'm using a couple vivosun 300watt leds in my set up and I understand that a lot of people are against the whole blurple lighting and what not. I've heard quite a few say that a lot of that energy goes into the cooling fan. So my question is, if I disconnected the cooling fan from the light, and hooked it up to a different power source, would all of the power the light draws go completely towards the light, and ultimately make it more powerful and efficient?
Or is that just a bad idea, and not worth considering?

The fans are on a separate driver normally. It's the leds themselves that are inefficient and under powered. As well as the drivers themselves.

Ahh well next grow I'm thinking about switching to either quantum boards or either mh/hps. Quantums are just so damn expensive, and the hid lights put off so much heat.
Ah I'm sure I'll work it out

Hid lights actually put out only a small amount of heat and are inefficient heaters of air, mainly you struggle to work out hid so you say they are hot....

I assure you all bright light is hot :-)

That's why they are called "high intensity discharge lights"? And why 90% of the time they are used with a cool tube of some sort.

How much wattage would I be looking at needing with these?
Like it's all kinds confusing, most lights say like 400watt equivalent or can replace a normal 200watt light and so on.
Say I have a 2x4 area with 3 plants. How big of a set up would you need/how many watts?

When using LED lighting most people figure between 35 and 40 watts/ft

FME 60-70% of hid lighting with good diode's.

Damn man that's just so expensive...
It seems like it would be like 1/4 the cost to just use mh/hps with cool tubes and upgraded ventilation

This is a guiding decision when considering using 'good' led fixtures.
If you have the ability to manage the thermal load from a HID fixture, the up front costs are usually less than 1/2 the cost of a equivalent led fixture. HID works very well as long as you can manage the environment.

Eh maybe when tax season comes around I'll consider the quantums, but I'll probably end up going with the hps/mh
Think 2 1000watt hps and mh bulbs would be close to enough for a 8x4 area?
Maybe a 100cfm cool tube going to each one?
Would think I could set that up for no more than 600
