Ummm... why exactly would you expect them to suddenly die, that must have been a joke?  ::)

I've had a couple of dozen orchids and about a dozen chili plants under 2 x 90 W UFO's for about a month now, and it does look quite promising. The bonchis are growing lots of new foliage and the orchids also seem to be thriving- several of them have started/ are starting to rebloom which they simply would not do without adequate light. My sudden death habanero (which I did not cut down fully though) also seems to be starting to bloom again!

The only downside is the noise from the fans and the not-so-pleasant colour of the light as I have the setup in the living room (daytime only though). Well, at least the neighbours probably have something to talk about- once again   :P

hello everybody,

I've recently got such an UFO too. I've got it directly from a chinese manufacturer, so dealers inbetween were avoided.
here it is:




Now, I had the curiosity to measure the power consumption of this lamp, usind an energy/power meter for home use (bougt in superstore with 12 eur). I don't claim it to be very precise, but:
the surprise was to see that the wattage of the 90 LEDs ist only about 54W wich shows that each LED has not a 1W power but just about 0,6W.

Hence an appeal to all of the owners of UFOs: could you please measure the wattage of your 90W UFOs and tell me the results?

I've already contacted the manufacturer an ask him for an explanation.

Look what he said:
please don't worry,it is normal phenomenon,for new led fixture,its material will be activated day by day,
and its power will eventually rise,it can reach maximum power ~90w after 2~3 months' use.


I find this explanation hilarious! I've never heard about such LEDs!!! Have anyone of you???

hi keto,

to lower the noise, open the lamp and replace the 12V adapter of the fans with a 5V adapter. I used a 5V mobile telephone charger, capable to give 5V and 500 mA, since each fan will take about 150 mA. Under volted fans are silent an still ventilating enogh air to cool the UFO (wich is cool enough, anyway)

now, my UFO is quite silent and it shows no sign of being a little warm!

Hmm, that sounds like a good idea when the lamp is being used indoors...
In a hot greenhouse the more powerful fan is good to have I guess.

They should have adjustment for the fan on them. :)

OK, in a greenhouse I wouldn't do the modification. I don't think one would care about the noise in a GH (well, perhaps he would, if a dozen UFOs are installed?)

Tell me, Fatalii, did you have the curiosity to measure the wattage of your UFO Lamp?
