Just got the silverstar6. I will test with glass only seeing how I dont think anybody would run these without glass. They are really light weight.
I will try and post the data tonight or tmw. Should I even do the silverstar 8?

If it isn't too much of a hassle, yes!darthvapor said:
I think that will effectively demonstrate how much of a role the size of the cooling ports makes, since (from what I can gather) the SilverStar 6 and SilverStar 8 are identical except for the size of the AC ducts.

Darthvapor: thanks for taking the time to do the light test.
Props to the hydrostore for being so so cool
Radiant @ 18"
Radiant @ 24"
Radiant @ 30"
Okay now analyze the charts

sweet graph. Makes it easy to compare to one another. props to the hydrostore for sure greengold.com rocks and they have a store in oakland too called d & s. way better then the place I used to go to. silverstar 8 is next and when they get stocked with the super sun 2 Ill test that too.

anybody know where I could download a copy of excel. I looked for about 20 min and got frustrated with all the bs.
If you want to go the legit route, you can also download a trial / evaluation copy directly from Microsoft:

Strawberrycough, sup!!
Wow with these charts you can really SEE the (effective) footprint shape and pattern. I'm guessing the differences in the size of the intensity points between the SilverStar and Radiant as you see in the above post is due more to the tiny differences in the distance between the bulb and glass (where the measurement began, since even 1" can double the intensity) than the design of the reflector. But I'm just guessing.
So right now I'm thinking that what's more important than looking at the intensity levels (when comparing two different reflectors measured differently) is the actual SHAPE of the light footprint and how well it evenly covers the measured space (in this case a 5x5 area).
It's very interesting, for example, seeing the difference in the shape (and effective size) of the light footprint that an air-cooling port makes. Or rather, the effect of the lack of reflective material at the ends from the use of an air-cooling port:

Of all of the reflectors that have been tested, which ones stand out the most? I'm looking to buy an air cooled reflector soon, and from what I read from the first pages of the thread, the Super Sun 2 is a good choice. What are some other ones to consider?

^^ I made an error and labeled last two pixs as radiants...but they are silverstars.

Tell me a bit about your space bluenorth. Seems some are better at illuminating rectangular spaces and some square.
darth, your willingness to do all this tedious testing and access to a large variety of equipment is paying off!
Even if not measured at the exacting points, the data still clearly and fairly accurately demonstrates how effectively a particular reflector spreads light and in what shape to fit your specific needs best.
I feel that the exacting points are largely irrelevant because in this our indoor cannabis hobby, lights are typically placed so close that most of the relevant amounts of light will stay inside of the "canopy" (test area, in this case 5x5). Anything lost outside is considered an irrelevant amount since the bulb is placed so close, and your canopy and room setup should be tight enough to minimize the amount of loss. Unless of course it's blatantly obvious (from both numbers and visuals) that a reflector's poor design is causing a lot of loss outside of your desired footprint...
What do you guys think about that?

Hi Darthvapor, my idea is to use 4 600watt lights (lumatek ballasts) to cover a 6x6 foot area with 9 5gal dwc buckets. I'm going to start right now with 2 lights and 6 buckets for my start up run. so I'm looking to cover a 3x3 area per 600 watt. I've got the blowers, can filter etc. I'm down to which reflectors now, any advice greatly appreciated
