Comparison List Of Light Technologies

Here is a list comparing grow light products and technologies. Showing data such as photon flux and cost per umol for performance & economical value. Many LED manufacturers only provide calculated values which provide unrealistic data as the calculations are a maximum theoreticle and do not take into consideration of factors including stabalization time, temperature and electrical losses. A LED fixture often has around 15 - 20% lower efficiency than what is calculated. I also provide estimated data for fixtures that do not have or provide any data on the fixtures light values, which is common for products that manufacturers know that do not perform well enough to warrant advertising. These estimations are taken from measurement data in the field which are not ideal, but provide good enough data for a rough approximation.

 

So remember

True measurement is a method of testing the full light output using sophisticated equipment that captures all light and directs it towards a sensor. 

Calculated measurement is a mathematical value determined by data provided by the manufacturers from the diodes used. This is an unrealistic value which typically is 15-20% higher than what would be seen with a true measurement. And the error can be even higher if the calculations are overblown.

Field measurements are real world measurements using physical simulated testing stations that imitate the same conditions as a growing environment. The data from these systems are typically lower than true measurements (by about 15 - 20%), as they encounter variables that introduce successive losses during testing. 

 

Here are the approximate desired canopy PPF requirements for different sizes of grow areas.

Update 8/2019:

We are now reaching the stage where LEDs efficiency and economical value are catching up and with some products, exceeding that of HID technology.

Thoughts on Mars hydro vs Viparspectra for just some extra light? As in the middle of my grow distance between my hps are at the higher end of their area so I’d like to add some cheaper LEDs to help boost the par/lumens in those spaces

Hey, Fantastic info. I heard you on a Podcast, Michigan Bros Show I think.

Question (s):

I have a 3x3x6 tent. I'm trying to keep it low cost with LEDs. I purchased a Mars Hydro II 900 a few years ago. At the time they said it replaces a 1000 (lie). I am willing to replace it if that gets me on track for a nice quality grow. Looking for quality more than quantity. I keep hearing about "blurple" lights. Are they a bad thing? I will be hitting you up on many other subjects. I'll try to keep them to the correct post area. I love gadgets!

Hi Doc, Im not sure if you've looked into them but I'd love to get your views on the meijiu and kingbrite QBs from Alibaba. They're now using the samsung LM301H diodes that claim above 3.0 micro mouls per Joul. They can also be optioned with some 660nm epistars. They come with a meanwell drive and aluminum heat sink. The price is too good to be true aswell. Links for you below

Edit: fixed links

I have a couple Gavita 1650e , still dailing in a couple things. The last couple runs my fan leaves would bleach and lose color  almost chlorosis like in a week 5 (only in late flower) I thought maybe it was because of the light intensity so I decided to dim my lights down to 50% with a Gavita master controller.Now I’m thinking I might have to double down on my cal mag because of the intensity of the light the plant is eating more cal mag . I’m in ProMix Hp Using advanced nutrients entire line Running A/c ,Dehumidifier co2 room temperature in week 5 is about 80-82 Rh is  55-60 % leaf surface temperature is 79 

 but I’m not 100% sure w the issue is or where it’s creeping from .

These are the beginning stages when I first noticed anything then it just progressed ,  I started off at 50% intensity on the gavita master controller and started ramping up 2% every day when I reach 75% intensity is when I started noticing color Loss on fan leaf then it progressed at that point I dim the back down to 55% . Very sorry for the late response as I’ve been getting familiar with the site , Very grateful for your help & advice  I know you’re a busy man  !
