Air cooled reflector testing with Digital footcandle meter

[Guest]

Yamaha 1Fan, is the cup of water straight from the tap or at room temperature? Can I substitute a handful of crushed ice for 7 ice cubes, and use vinegar instead of lemon juice? I don't have any lemon juice.

darthvapor, what a waste of sippin' whiskey. lol

I finally learned to use excel and compiled all the data into graphs using the same scale and colors. I saved my work, and 3 days ago I spilled whiskey on my laptop and fried the f*cker. Took me hours, I also had my data for the test saved on there too. Im pissed about the data and the laptop.

The hard drive itself likely isn't damaged by your whiskey incident. If you get a new laptop (or have a working desktop), you could take the old drive and hook it up to a USB adapter for internal laptop drives and still get the data off.

Pico contact for more test subjects.

Pico contact for more test subjects.

Pico due to my lack of post i cant contact you. I was hoping you can send me a pm with some contact info. I have a couple offerings to be tested.Or someone reading this will you please send pico a pm and let him know. Thank you

 

[pico]

You got me, this is my place of contact right here. If you were expecting a phone number or email, I can't help you there. Sorry, security is key. So let me know what you have on your mind right here in this thread, or PM me when you get to 50 posts.

Two reflectors for testing

Two reflectors for testing

I would like to send you two reflectors to test and post your results here on this forum. One will be a six" air cooled compact and the other will be a 6" or 8" (your choice) larger air cooled reflector. just send me a pm with a safe address and i will ship them UPS from oregon in a plain brown box. Yes they are free and yours to keep.

 

[pico]

We can figure something out, I am always looking for a better product. Do you guys have a website, or pictures of your offerings....or any information on the company?

Maverick sun magnilume pro and Superwide 6" or 8" is what im willing to send. You will find further info at www.mavericksun.com

 

[pico]

I like the looks of these things. Too bad, I lived right next to you guys about 6 months ago. I will get a safe address and send it over. I don't think you can open a PM until you get to 50 posts.

 

[Green Inc.]

well one hello every five minutes in the introduce yourself forum and ill be ready in a few days.

So, I finally sat down and plugged in all the data, then made a nice auto-magic spreadsheet to go with it

I dont have any particular software to speed up the screenshot taking, so instead here is the source. I figure most of you have excel anyways and this is the easy way.

In the spreadsheet there are 2 graphs, one for picos numbers and one for dathvapor numbers. Just select the dropdown boxes on the left to choose the reflector and distance and it will draw a nice graph. The axes are locked in place. This is good for comparison purposes, although the range that works on 18" might not be so informative at 36". The file isn't locked in any way so play with it as you will.

I hope this works, i just found a website that let me upload an excel file without wanting registration.

P.S. Thanks to pico and dathvapor for doing all the hard work. I almost bought a light sensor to do this as well but you two have done a great job. Picked up an infrared laser thermometer instead

Already remembered the first bug

When dathvapor posted the results for the Yieldmaster II 6" @ 18" he gave 29 data points
Since i moved arround the input data w/cut and paste the extra 4 datapoints are nolonger below the xtrasun6 line, but they belong there

My guess for the proper data is the following, but its only a guess.

470
1150
1520
1210
620
980
3970
6070
4290
1160
1370
6260
10250
6900
1610
1280
4220
6380
4220
1280
810
2340
4220
2390
880

P.S. You can highlight that, and drag and drop it into excel at the top of the column, it will fill the whole thing in

Figured out how to plug through this semi-quickly with photoshop. These are all the mid-range numbers. Using the w/glass numbers where both are given.

 

[darthvapor]

thanks hurricane.


green inc and pico...my local hydrostore said you can send them there its in oakland. I can pick them up and drop them off when I return the bell reflector to you. Who knows if they test good maybe the shop will distribution them


p.s just did the pvc trellis,,way better then the stakes I was using. so simple its genious. thanks pico

 

[pico]

good call darth. I think shipping the reflector to your shop is a good idea. I was trying to figure out something like that. I do need to get that bell reflector back from you sometime this summer. I am sure Bell is wondering what the hell happened to me. Hell, maybe they forgot they loaned it out to me.

Glad you like the PVC trellis. I use it for everything it works great. Hope your new setup it coming along nicely.

hurricane, thanks for doing all the graphs. I still think we need more data points to get a good graph. The best way to compare at this point is to sit down and look at all the numbers. I am a number guy though. Other people are probably not as number crazy as me.

 

[dongle69]

so what do ya'll think are the better ones ?

radiant 8" maybe ??

That is what it looked like according to the graphs.

 

[darthvapor]

bell and the super sun 2 in my opinion

Did any of you test a Adjust-A-Wings?

Its going to be difficult to test it using the same procedure used for the other hoods tested, because double parabolic reflectors are designed to provide a evenly lighting along a wider area, so the square used for testing the other hoods probably is going to be too small to offer meangliful results.

Specially if wanting to extrapolate data for total hood efficiency and such. In order to check just the footprint, wich for me is what this thread has caracterized better, it would be possible, just using a larger testing square (or better, a rectangle adapted to adjust a wing's footprint).

Anyone?

 

[clowntown]

I just got a set of some brand-new, never-used ballasts, bulbs and reflectors... so now I will be able to do a serious side-by-side, Daystar AC vs SuperSun 2.

Anyone have a light meter I can borrow?

 

[nlvigour]

Alright!!!!!!!!!!! Sounds Great...

Alright!!!!!!!!!!! Sounds Great...

Way to go Clowntown I've been waiting for the Supersun 2 vs Daystar AC comparison for a long time.

Pico and others have done a phenomenal job with this thread. However, now the gift of two similar reflectors and the wisdom to establish and duplicate the exact perameters I too am extremly curious to see the results. I wish you the best.

If you get a hold of the new "silverstar slim" which has similar dimensions to the aformentioned hoods you are testing - that too - would also be great.

Best of luck.
