Spectrum King 600 series - "95% efficiency"?

I did a quick search for threads. Didn't see too much. Anyone know anything about them? They seem to be an LED nerd's wet dream from the looks of them! ;)

tell me more if you know. thanks

Crazydago on YouTube was one of the first people to get a one and did a review on it.
I personally have 4 of their 100 watt closet case lights for veg in a 4 x 8 and my plants love them
If the 600 works as good I would buy in a heart beat just my personal opinion

im sure they are great fixtures, but to say that 92% is anything but misleading is...misleading.

almost as misleading as using lux and a single spot reading 1 foot from the panel as your specifications

thats the drivers. how effiecient are those LEDs?

well its 168 cree SMDs @ 3.5W each, just figure out what kind of chips those are and you can look up efficiency with PCT

"medical-grade driver"

oh...and I was wrong...it wasn't 95% efficiency....It was 92% efficiency (3:30 mark)

The guy is just a salesman. My Meanwell HLG-600H drivers are managing 95.5% efficiency (tested power consumption myself).

"Medical grade drivers"... Lol.

He uses every opportunity to bamboozle buyers. People like him a big part of the reason LEDs continue to have a bad rep. He doesn't care as long as the money's rolling in.

some more informative info from their site:


C.O.B Myth and High Wattage LEDs
Another point of confusion for customers is the constant advertisement of C.O.B. (chip on board) LEDs and how they will dominate the market. As a commercial manufacturer of some of the best grow lights in the business, we are here to tell you that their popularity and dominance are a bit overblown.

C.O.B. LEDs have been around for over a decade. There are only three reasons to choose a C.O.B. LED:

  1. Reduce the cost of materials to make the LED
  2. Save money by eliminating the need for circuit boards
  3. Group more LED diodes into one small area
C.O.B. lights offer lower efficiency and overall light output. By adding and cramming more diodes into a tight array that share the same substrate, heat becomes a big issue. As the C.O.B.’s run hotter, they:

  • Emit fewer lumens
  • Have a lower efficiency
  • Develop a shorter lifespan
Take a look below at some of these in-house made LEDs and how they discolor and degrade over a short period of time.



DON’T BE FOOLED BY COMPANIES THAT CLAIM TO OFFER HIGH WATTAGE CHIPS!!!
Standard self-contained diodes are the leading LEDs in the industry and have performances that are double that of C.O.B. LEDs. Every LED that claims to be 10, 20, 50 or even 100 watts is a C.O.B.

Cant blame them for marketing. However they are using some older chipsets and for those prices they should atleast be using the XPG line.
The claim that higher wattage COBS are not as good as single diodes is just lies.
I would never buy one due to the lies they tell and the altered PAR measurements.

Yes i have no issue with the product, the design is fairly solid with the heat pipes and theres certainly nothing wrong with single diodes. take same product, strip away the claims and misrepresentation, throw it in a sphere and show us some ooohmoles.

i mean cmon some of these claims are ridiculous, it shows a clear case of someone who doesnt understand LED fundamentals and more importantly thermodynamics. He literally says in that video that the fixture is 92% efficient - 610W of light and 40W of heat.

"Extra efficient heatsinks lower overall ambient room temperature"

where can i buy these magical heatsinks that actually remove heat from a room

and their claim that you can only put 2 gavitas per ton of AC is bullshit.

1150W = 3923 btu = 0.32 ton

consequently, they claim you can put eight of their 640W fixtures on a ton of AC. think about that for a second. that would mean it would use 1/4 of the power of the gavitas (288W) - yet its listed as 640W.

640W = 2184 btu = 0.18 ton = 5.5 fixtures per ton

SK actualy did put their fixture in a sphere. Or more accurately, Cree staff did when they performed a TEMPO test.

I'm a noob this my first grow I know nothing about efficiency but I like the way my plants respond to the spectrum king closet cases at only 400 watts in. 4x 8.
I would actually like to see an independent party test it before I buy the 600 these are my ladies at 6 week veg under the closet cases
