500 watt bulbs can get EXTREMELY bright!



  • Since I don't go outside much and it can be cloudy, if I'm busy one day, I got some 17,000 lumen bulbs to use inside! The packaging on the bulb says they last much longer at eight hours, instead of three, so that's nice. The CT is around 3400K just clear frost, and wow this thing is absolutely massive, still using the medium base. I'd like to see an example of it on the fluxometer.

    Edit: After thinking about it, I think you've already covered it with the blue mazda day lamp. That one is even whiter because of the blue coating. Specifications say that some of these can get near 5000K but I don't believe them, that's got a very heavy coating--besides I didn't want a daylight white, just something to counter other lights with somewhat of a warm white.

    They are referred to as photofloods and I think they would be great as wake up lights without spending a lot of cash outside the cost of a device to brighten them in the morning. The issue is I can't run them on most dimmers and most wake up devices only do about 300 or 400 watts, so I'm out of luck. I did get a lot of 250 watt and 300 watts so I could let those last a bit longer, and they'd be great on those devices. I'm still looking for the one that does 400 watts, I think someone on the forum mentioned it as the "Sunrizer" or something similar. So far I've found the "lighten up" that's mentioned on lifehacker.



  • There are 500 watt LED chips that can be found quite commonly on eBbay for pretty decent prices. They're crazy. Something like 60,000 lumens. From warm white to very cold white (bit harder to find) as high as 20,000K. The only problem is they're not quite just plug & play. They need a pretty beefy DC power supply to work and a decent heatsink to dissipate the heat they make, otherwise they'd burn themselves out in a few seconds. I guess one could make a somewhat sketchy, jury-rigged type of setup for one. Or just use a 100-200 watt led since that would still be plenty. I guess I'm not really going anywhere with this, just putting it out there.



  • @Brandon-U Yeah, I'm not experienced with LEDs like that. Also, currently it's winter time, so it seems like a waste to cool down the LED. Maybe they'll come up with a way for them to not burn out so easily without massive heatsinks and such, I'd like to have some artificial sunlight in the morning from a nice led.



  • No, the heat generated by the LED light's power supply must be dissipated or else it will overheat and die. This is why LED lights should never be installed upside-down, inside enclosed fixtures, in hot areas, etc. Yes, they don't feel hot immediately like an incandescent does, but that's because it takes a good 15-20 minutes to become hot. They also don't radiate this heat outward like an incandescent because nothing is burning. In an incandescent, the filament is burning, thus it's instant radiant heat.

    Even the heat created by all of the LEDs themselves must be dissipated.

    Until we humans can figure out how to generate power without heat being created as a result, we will always need to dissipate that heat or else it will build up and build up and overheat.
