I haven't used a air cooled reflector in quite awhile.
I like the econo wing. 40 bucks, throws a good pattern. With 10 lights, you should be able to saturate quite a large area, with plenty of light. Look how far apart I have my four, and my plants are doing fine.

ya as far as hoods in commercial setup nothing beats a super sun 1 v1.1 (the orginal dimpled and Polished the new dimpled arent as good hence the loss of the Lighting Science Group Design Logo any more..)
with a 3x4 great pattern..
I personally seen 20+ ops using 12-23 400's and 8 running 24+ 400s
there have been few others i haven't seen personally (obviously) but know they are large op.
ive been waiting for the commercial/big boys to start using cmh and chiming in like few have recently before really touting them.for large ops..as. most think bigger is better (ie large wattage high lumen)
really the next cmh we are going to promote is the Philips City Ver 2 (the current ver 1 SUCKS for Horti)
as far as lumen s in any lamp we are finding some lamps to seem brighter to all who see but less rated lumen s.. the lumen scale is even wrong for eyes..
some group needs to really redo the math on these things..LOL
chef rewire the timer thing with more outlets.. simple job..
as far as cost.. for that many email ur supplier for a better price..
if you do it all commercial opps using cmh or mh or even hps need UV protected Sunglasses not on the UV standpoint but its "Snowblindess" no ifs ands or buts..
you will suffer from it and wont be nice.. (only from staring at source on small opss or large ones that you just cant not see the source cause there all around u)

I'm sorry. Could you explain this statement? The next version will be so much better, to where these bulbs "suck"? That's sounds pretty good.

Thanks for that link freezerboy, read all 27 pages lol
@ CTSV - I came to the exact same conclusion, $40 Enconowings
Bang for the buck winner hands down IMO, a little lumen loss but great distribution. A trade I'd make without the $ savings.
@ Simba - I will rewire that, good call. Thanks for the eye warning too, I usually do, but will stop cheating for sure.
What is the best CMH bulb available right now?
I sure won't miss the MH/HPS swap outs.

ctsv,

you "I'm sorry. Could you explain this statement? The next version will be so much better, to where these bulbs "suck"? That's sounds pretty good. "
philips released a 300 watt CMH called the city, dumps 38,000 lumens vs the current 400 cmh at 34,800 @ 400 Watts..
the city has a 126.66LPW and the current 400 cmh @ 87LPW
mind u we dont like LPW>. or even lumens even for the eye lumens are crap LOL
but this shows with different chemistry we can fully change the SPD to be either More green/yellow (the Ver 1 City Lamp) or with the Ver 2 we know is in the works with a more red/blue output.
even the current city doesn't grow as well as a 400 cmh (cdm400s51) (tested)
also the 300 watt city has its own Special Ballast that will have a $$$ price tag..
keep asking for 600+ so i have to let everyone know bigger wattage is not where cmh is headed..
even for Commercial lighting the 300 watter would replace a 600 MH in an installation for cost to run and relamp etc..
long story short.. cdm400s51 is best out there for the next 6-12 months..
even when cmh city ver 2 comes we are expecting cdm400 to last a long while for the simple fact the ver 2 will have a $200+ ballast alone for a little while..
watch adv techs site.. as soon as any thing better or other great products avail.. they will allways be the first.. Fact.. (they try everything before anyone else has a clue its even coming, and promotes Qaulity lighting not profitable crap)
my personal philosophy in life and business don't sell or buy CRAP>>
ya if u going for bang for buck depending on setup batwings are ok.. id go white or dimpled no polished.. the best reflector impho is the philips 400 from UK. nice oh so nice.. great for multiple or single lamp use but $$$$$

Thanks for the info Simba. I will probably end up sticking with the 400, since I already have the five 400w ballasts. Sounds interesting though, might have to get a couple to supplement the other 400s. I'll keep checking adv tech.
chef, I think you will be just as happy with your results with the econo wing than anything else. I get my ballasts (sunsystem 10), econo wing, and CMH bulb all for 250 locally. You will be able to find a better ballast and hood, but not a that price point.
I also find myself asking this question, "Do my skills, merit a better reflector?". My answer is "No". I feel I have many other things to perfect, before I start to blame it on my equipment's effectiveness. It's the same with shooting, you can go and buy a 2500 gun and shoot the exact same as you would with a 500 dollar gun. Yes, the 2500 dollar one is "better/more accurate", but if your skill can not utilize the enhanced performance, why waste the dough? (cooking joke).
"What is the best CMH bulb available right now?"
Correct me if I am wrong, Simba, but I believe these are the best 400s/ only 400s...

CMH Doesn't Suck
CMH Doesn't Suck
I can't believe they are trying to improve these things. All we wanted was a higher wattage.
If CMH sucks then why are my plants showing so much vigor and strenght? I'm looking forward to a good yeild!
Day 36 Serious White Russian / Mandala White Satin Grow ---In progress.
This site is running slow , so I give up trying to upload the photos of day 36.

Chef, DON'T run CMH with a digital ballast. It will smoke the bulbs pretty quickly. I speak from experience. The shape of the arc tube is a minefield of resonances just waiting for the right frequency. To run a dig ballast you'd need a GE low frequency squarewave ballast that isn't cheap. ( The last time I checked was 6 months ago)
They do however, work beautifully on Mag ballasts. Best bulb on the market. PERIOD.

Ok.. I read this now and see "the current cmh sucks for horti"
Well, I'm looking for one for a micro grow, a 150w lamp and it appears philips have renamed them CDO-TT for a tubular lamp. the webby says "formerly known as CDM-T" They are Philips City Master lamps..
Hmm looking at the specs they're 13,500 lumens on a magnetic ballast. I'll be running mine on a phillips digi designed for it..
Is this any good for around 2-3sqft? or do i have to rethink.. 150w digi ballasts for HPS just dont seem to exist in the UK and i AINT running a mag..

Only reason I raise mine is to max out the footprint.
My latest Lemons to Lemonade story ... My freezer's inside door is falling apart. With the shelves molded into the door gone, I can rotate the hood 90º, perpendicular to the grow. Now I can lower the lamp and increase the footprint. Woo hoo!

FreezwerBoy,
If I may suggest something, I found my freezer on craig's list for free. Reclaimed the refrigerant and stripped it out. Mounted the ballast where the compressor was and then added the controls you saw. I a few minutes here I will post a pic of what I did about the darn shelves on the door.
Basically, I lifted the gasket to expose the phillips screws holding it down and then removed the gasket and door panel that has the molded shelves. I measured the door panel and went to the local Home Desperate and had them cut me a piece of fiberglass white paneling to match the measurements of the old panel. Then I just reversed the process with the fiberglass panel going in in place of the old. Just a thought and not too expensive. Under $30 US
Going to take pics be right back ya'll!!!

guys girls..
i didnt say the current CDM400S51 sucks for horti..
The Current Ver 1 City CMH is the one that suck and doesn't have the Correct spectrum..
mack, ya higher wattage cmh than 400 your cutting LIFE, and introducing other obsticals .. so why not jsut find a way to make 400 watt and lower Super efficient either for commercial or horti.. (beyond the benefits of current CDM400s51)
sb, chef, ya no Digi ballasts there crap any ways.. read what lumetek.co.uk says on there site if it leaks resin let it cool PHH PHHKKKK that.. im calling firebrigade..
oh no Horti Digi ballast is UL listed. so if your house burns god forbid... no insurance check for you if that non listed is pluged in even if it didnt start the fire.. you have no more insurance.. and in an apt. your liable.. for any thing bad from Gross neglegence. not that you'd have to really worry the boys in blue and red will be there to help you...
as far as the 2 id recommend ge ultramax or advance both low frequency versions..
there is also another not on the market that i think is awaiting ul approval..
a dig ballast will only save if you have min 4+ and are using on 220V.. (cleaner line)
otherwise for 1-4 lamps magcore will last longer and be cheaper in the long run..
AZ, FB, ya mesa got a fridge here that i wanted to convert but i feel bad every time i go to pulll the comp. its 30+ yr old but still works..
great idea pull the inner door out....

are the philips city master CDO-TT (CDM-T) 150w 2800k any good? by that I mean comparable/superior to a typical 150w HPS 2700k?

captin,, you need the 4000k Master Color Line (usa lineup)
if ur running 50-150 watt then heres the link of models u want to choose from.. DONT DEVIATE FROM PART NUMBER>
also get the protected versions.
tubular lamps are not safe and in long run more of a pita than worth.. the above are small like regular bulb but smaller a bit..
and the 50-150 can run on the digi philips if it says specifically for ceramic lamp..
mag ballasts are great for 1-5 lamps.. id rather use mag over current electronic.. (even for low wattage) keep them cool with simple heat sink and fan and the energy consumption is made up for by the longevity.. (ie fix ability when ignitor goes.. and it will go on both digi and mag)

4000k to flower under? This is for a micro flowering box. damn this shit is more complicated than I thought.. lol
Can't find anything in the UK that works, dammit.. all 150w hps are 2050k.

yups 4k to flower, veg.. its a one bulb..
the super long version super shortened..
hps half energy is wasted in yellow and just bairly red.. (very little absorption in those ranges)
cmh 4k only 20% of its energy is in total little absorption range. and rest in High absorption ranges..
3k cmhs and city's are same concept as HPS.. more of its total percentage is in bad ranges.. even though good amount in great areas full spd more than does it..
again super short version.
