Calling out to Weezard for LED advice
There were no photos to find.
I just opened the pup and described the innards to Hermie.
Did not bother to take and post photos because there is just not that much to see.
3 small black boxes. 3 small fans
The box that powers the fans, is prolly an unregulated 12Vdc supply.
The other two drive the red and blue series strings of leds.
They are true black boxes, no markings, so I hope they are constant current supplies.
(could be just a bridge rectifier and a dropping resistor.)
Anybody know a friendly dentist who will do a "bitewing X-ray" of the BBs?
The answer you got on the current draw was boilerplate, but, of course, accurate.
Mine actually draws 650 ma. at 120v. and that includes the 3 fans.
In spite of that, it does veg. very well. :thumbsup:
Almost too well.
DWC'd momma got too big for da room,
hadda put her in bloom.
I'd say, order the dual blue and buy one of those cheap KWH meters.
For ~$20. They will tell you the actual current draw, power factor, KWH, real-time voltage, etc.
Then you can test all your appliances to see which one have their hand in your pocket.
"Should I be concerned that they make their own LED's?"
Not if they make good leds.
If you have a decent lux meter, we'll compare notes and measurements
If you don't have a light meter, a calibrated eyeball will tell you if they are crappy.
The relative "brightness' should be the same for all leds of the same wavelength.
And they should be way too bright to look directly at.
So, get a money-back guarantee and place your order.
That's why we buy "samples", yah?
How 'bout, title your veg. log.
Two blue?! Who knew!?
Aloha,
Wee Zard
