I have 400 w halogen lamp now, but I think it is not enough environmental protection, what I want to ask is which leds can replace it, this problem bothering me for a long time, I really appreciate if someone tell me.

I haven't see any LED lamps that produce that amount of light, that's available for home use anyway.

How so?. I have not seen ANY LED replacements for home use that are even close... the brightest ones you are going to find in a store right now emulate a 75 - 85 watt incandescent bulb. Commercial applications might... but I'm not as familiar with them.

I do have an outside flood light that is a 50 watt LED ( think it's a 150 watt equivalent) but it's a lot bigger than a toaster (a lot for heat dissipation) and is self contained, Not something that fits any existing fixture. ( nope not at all impressed with it either at the cost)

And I'm an Electronic Engineer that has been keeping his eye on these. Mostly because I have a lot of large wildlife that frequently trips my motion detector equipped floodlights that would put a dent in the electric bill...

I look at how much is it going to save me in electric bill costs... over its life.

No. Check back in a couple of years...
