#5. New Led. The new leds available rn that will give you close to or better spectrum then the CMH (finally) while maintaining 2.1-2.6 umol/j. Those efficiency ratings are only measuring between 400-700nm. That provides the typical PPFD. When measuring the true spectrum you'll get a higher PBFD.
Representing the Normal par as well as what they call "The Beyond Par Region" (a term used to admit a mistake it sounds, lol!)
These New High-End (all in one true full spectrum with no need to supplement) Led fixtures are the best of both worlds I'd imagine. Still waiting on mine to arrive.
There's a few out there that know of:
1) Amare Bar-6 LUV. Canna-Spec + 385nm.
Canna-Spec spectrum includes x2 whites, 470, 630, 660 + 740nm to create a broad Horticultural spectrum.
On dual remote driver channels with dimmers allowing spectral blending & dimming between veg + flower modes.
-DIodes: 301H + Samsung SSL or optional SQ. LG- UVA.
-Foldable & detachable
-660w x 6 wide bars with protective coating over diodes.
-2.6 umol/j
-25% off Pre-Orders = $975 to your door.
This company is well known for its customer service + satisfaction, giving large discounts, helping our Veterans, ect... dont wanna sound Shilly. They creating the first Premium parts used & listed part #'s on the site, custom designed, enhanced white, Canna-Specific fixtures & was the first to state publicly they are designed to be used specifically for growing Cannabis when it was not publicly accepted .
Apache & Area51 opened the doors to enhanced white & Amare perfected it the best they could with the newest tech each yr., upgrading when possible.
New Website underway. No Bar-6 LUV on the sight yet. Basically this spectrum with a tiny bit less 450nm peak & the addition of 385nm. Providing 15% light outside the normal par region.

Another one out now is From the SE bulb HPS leader company : Hortrilux
This is less efficient then the one above but also a nice all in one.

Then there's these guys in which i support their work & admire their design. They have yet to incorporate UVA but do something the 2 listed above do not do. That is provide Near UV which in turn fills the lousy gap white leds have between 400-450nm as well as extend the red tail into the Near IR zone.
This has allowed increases bag appeal as well as up to a 20% increase in thc & other cannabinoids shown through testing. This approach is called using a BroadBand spectrum which creates a light closest to the sun (in one chip) by means of only x2 diode k-temps.
They started as members here on RIU.

All x3 of these Led fixtures will eliminate the need to add a cmh, have 3-5 yr warranties, are HE, Reputable companies (Aussies are new but still very reputable)
These Full-Spectrum leds are a slightly higher upfront cost then CMH, allot more then SE-HPS but Would reduce your electrical needs by either 50% or close, reduce or eliminate the need for AC.
If you already own a CMH or bulb fixture & are looking to get started cheap then i would just add an led Bar to each side n be done until harvesting enough to buy a good led.
Hope this helps. Good Luck!
