Anyone try "LED Corn Bulbs"

[Dana Riddle]

I've had my eye on those for a while. I'll get one and test it.

Love it! Thanks Dana!

Just ordered a '50 watt' 6500k corn cob LED. Should be here late tomorrow. Will look at PAR, Kelvin, wattage and so on.

I have tired using ones like these before for plants in my reptile cage, not quite this strong but similar and the heat always made them fail for me.

I do think that reflecting LED output might be the next big thing, but that kills the slim and sleek aesthetic that people like. I would keep the ballast away from the heat, though.

Heat made them fail? How long did they last?

I'll take a look at operating temperatures as well.

Just a couple of months. I got them and put in a reptile clamp light type of fixture, and it did get quite hot to the touch. They were not these exact ones, but similar style. Perhaps they have been improved as this was a year or two ago.

Did those have an active fan inside cooling? These have a fan with outer clear shell drawing air through [emoji2369]

OK - thanks. Good to know. I'll probably use an inexpensive aluminum reflector while testing. I think I have some parabolic reflectors too - if so, I'll examine performance under both conditions.

Yeah, it's all about designing a reflector and an efficient heatsink that doesn't look ugly or massive.

It is about more than that, IMO. The LED manufacturers still advertise and people believe that they are more efficient. If they cannot pop a PAR meter in a small area, then more people will figure out that lighting is pretty much watt-for-watt just like Del Aqulia and others have pointed out. Also, I think that most LED folks would still want to be able to play with the spectrum, so no idea how that would work with design when reflected... probably better, but most of these corn bulbs are one-spectrum diodes... even if they were 14 or 20k, would anybody want one and not be able to change the spectrum or use the app? You can certianly argue that they might be better off this way, but would they want it?

These are by no means aquarium rated bulbs and will not be of benefit in the long run

Just saw a giveaway featuring these and was wondering if anyone had ran them on a reef or investigated par/spectrum in a Halide fixture?

I just started using, bought one after 3mo turning on off it went out. I have a seconded one we'll see.
Wasn't planning to use for Aquarium, but recieved 2 litophyton corals, I do NPS corals , so gonna try.
