Where do you get "Super Actinic" bulbs?

So when i decided to grow i started with a 400W hps and MH conversion bulb. I put up my tent and it was problem after problem. With the generous help from the people here i decided to throw away my setup and start from scratch. I purchased the Quantum Badboy 8 lamp T5. I started with the standard 6500k bulbs with some success. I wanted to buy an LED light but didnt have the money. So... i was at my buddies house and he has a LARGE aquarium and he showed me his bulbs..it clicked.. corals need light too and his lights produced the EXACT spectrum corals need to live and are capable of penetrating 3'+ of water. well corals and plants are very similar as they use the EXACT same light spectrum. Digging deeper i found bulbs that produce 410-460nm and 620-660 nm light.. That is also Exactly what LEDs put out..now putting one plus one together i decided to do a small test.. i bought 2 2' t5 lights ATI AND UVL Blue plus and Super Actinic. Explosive growth followed. i couldent believe my eyes. I was told on 4 different forums that actinic bulbs DO NOT WORK FOR plants boy were they really wrong!. i ahve since gone 100% T5 with various bulbs producing only yhe light spectrum that plants need. As you can see my plants are doing AMAZING for being grown with Actinic bulbs.2 of my bulbs are missing as they were broken upon arrrival. I will be changing out some of the blue bulbs with the deep red ones i found for flowering..they produce ONLY 630-660nm light. no other spectrum so i get 100% PAR. top that with MH...now i know what your thinking these lights are not bright at all... well its not about lumens.the human eye response isgreenscanarticle1.jpgphotosynthetic is action%2520spectrum%2520en.jpg, so your eyes do not see ALL the light these bulbs output. hardcore believers will flame me but let the math and the facts be known.HPS BULBS 800px-High_Pressure_Sodium_Lamp_Spectrum.jpg Anyone notice a pattern here???? Lumens are not the ending factor to bud growth or you could not grow with LED. my sample grow i netted 1oz on a plant with only 116w. If your still in disbelief consider this, chect the spectrum charts for your coveted 3000k bulbs and overlay it with your chlorophyll response charts.. youll notice MOST of the light these bulbs prodice is outside the chloraphyll A+B peaks... now place the spectrums of my lights and overlay them...100% match.. seems to me im doing something right?
Where do you get "Super Actinic" bulbs?
From looking at that chart.. Instead of paying $20ea for the actinic bulbs which i think are only around 400-600nm wavelength .. wouldn't it be cheaper to get just to get the $7ea full spectrum t5 bulbs since it has the blue & red spectrum that plants mostly need?
Ok lets do some math shall we? adinfo_924418.jpgEYE_MH_conversion_graph.gif here is two bulbs a common GE gow bulb and EYE hortilux MH bulb. now lets discuss what were looking at. You see the peaks in the 500 range? plants are NOT sensitive to green or yellow light spectrum so thats wasted lumens. Now those peaks are the percentage of light output at that spectrum. based on that analysis a LARGE majority of light is wasted $$$ wasted on unnecessary lumens. now look at the actinic bulbs.T5_blue_plus_Sm.jpgsuperActinic_chart.jpgRedSun.jpggiesemann%20fiji%20purple.jpg Now do we see where im going with this? electromagnetic-spectrum-of-chlorophyll.jpeg notice that any light that is output in the 480 to 600nm is pretty much wasted light? nuff said.
i purchased the following...
UVL Red sun 630nm
UVL Super Actinic peaks at 420nm
ATI Pro Color 660nm
KorallenZucht peaks at 630 and 440nm
i got all my bulbs from various aquarium supply stores. These bulbs are designed to supply hardbody and softbody corals with sunlight in the correct spectrum AND penetrate water up to 5' deep...these bulbs have been on the market for longer than any "grow" bulbs and have more worldwide research put into them. if you have any doubts read about PUR and PAR values and how these lights can provide 90-100% of the light plants need..without wasting light on the "yellow" spectrums. corals like plants use sunlight to provide energy, and grow.
A very impressive post. Here's some rep for your thoroughness.

I'm way impressed. Are the fixtures and/or bulbs either HO or VHO? And how long have you been using these lights?

all these bulbs are ho.. vho bulbs are actually LESS efficient and $ for $ not worth it. i shouldent need to post proof but can if need be...VHO bulbs are just overdriven HO bulbs and you can overdrive all these bulbs with an ATI ballast....ask for links if needed.
impressive.....this is a new type of grow for me to see.... +rep my friend
