Phillips Elite Agro 315w T12 CMH in open fixtures - Impressive!!!

[Large Prime]

We measured with a crappy lumen meter under two two identical reflectors. We placed it on marks layed out every 6" on a piece of white plywood under a pair of smaller footprint air cooled reflectors that we had. I swapped the socket on one and we set them up side by side and took measurements.
It was very rough but the meter only read more than a 5% reduction for the 315 in a few places. Then rest were right about 5% less lumen for the 315 VS the 600. We did 3 sets of measurements and averaged it and the math was about 5% less light. Not scientific, but...

On the site I first met you i just had a 'debate' about the 860W bulbs. the short of it is the agro is at least 2 generations newer tech.

the 860 is significantly better than hps. And a great bulb. But the 315W agro beats it in every way but the initial cost. And you can run 3 315W agros for the power of one 860. and get far more light.

How did you measure? Do the 860W CDM lamps have a similar profile?

 

[Large Prime]

these are pretty interesting.

Not to be a dick, but that reflector would be great for a parking lot, but suck in a garden. IMHO

Our results with them are showing they don't seem to provide quite the light the plants are looking for; we get pretty plants that aren't terribly heavy. I'm very interested in the newer tech, but I'd need a whole slew of them in a Super Silo to do any sort of justice! That sounds price prohibitive.

Regarding the other option, the DE lamp and fixture. EPapillon vs Gavita isn't a choice; neither provide the fixture I need. I'd love to do some kind of vertical DE setup, but I've never seen anyone try anything like it, let alone heard if it worked. I wouldn't know where to start.

lack of weight is prolly a lack of watts (Umols) per sq foot.
they are not that expensive. a ballast is 150$ from Philips, and the sockets are 10-20$ each. the bulb is ~75$
so you are spending a little more than a typical setup, but the bulbs last WAY longer and it is way better light.

Perhaps a Super Silo is not a great fit for them. I know we are putting more of them in than people expect, given the square footage, and we like the results.
Yes more up front cost and time. But better plants, weight, and less problems.

But YMMV...

How many square feet per bulb?

I was thinking four to six lamps in a six foot tall by five foot diameter silo arrangement. Depends on the needed watts per square foot.

I agree.............looks like a rush job squeezing two bulbs in their standard reflector.........

 

[Large Prime]

5' diameter is ~15.5' circumference X 6' = ~93 sq. ft.
generaly speaking about 100 sq t. would need about 4K lights if lighting with 1K bulbs. Or about 6x600W bulbs. So you could get by with 6x315W or perhaps up it to 8. If you go 315, you can also tan by standing in there for a few minutes every day. You will NEED EYE PROTECTING. NOT EVEN JOKING AT ALL.

So get a State tax ID and a federal tax ID and contact welthink and order 2 4packs of their ballasts.
either me or rives on the other site would be glad to help you wire them up

Lol eight 315W bulbs in there... I'm not even sure I could get them all to fit!

No lie about eye protection, it doesn't matter what lighting it is indoors, wear your UVA/UVB blocking shades allllllll the time, no exceptions. Otherwise, macular degeneration is how they'll know what you did when you were younger.

Actually, mac degen is age related... But definately do wear sunnies yes (y) how are these faring in 2017, im on the lookout for some new bulbs... Cant seem to find the phillips screw in ones anymore as it seems the only place that used to sell them no longer exists...

Macular degeneration is age related, based on length of time the eyes are exposed to UV light.

The cause is said to be unknown, but anyways, that was just to bump... Shall we talk lights? Im thinking to try the 4th gen sunplix ballasts with the 315w philips... Is the new 3100k better than the 4200k mogul base?

If given the choice, I'd go with 3100K.

heers thought thad b d case, the old phillips ballasts one of them would randomly go on the blink... An initial search for reviews of the plixt seems to suggest that the reveiws are well um glowing to say the least have any members had experience with this fuzzy logic stuff ing lights i have a washing mashine by lg i loved it so much i bought 2 lol anyways wtf is fuzzy logic? And how does it help lec tech?

I'm not aware fuzzy logic is employed by Philips in their ballasts.

They certainly do not yes it some other bizzarre logic lols

Babbagineer,

Thank you for sharing your comments concerning the Philips Elite Grow 315 watt CMH. I carry this line of bulbs and ballasts. So far our results show a greater yield, a shorter grow cycle using two of these systems to replace one 1000W MH and HPS with no need to switch bulbs. Lamp output with our specially designed ballast is 95% of original after 20,000 hours.

We are located in Denver.

 

[Crossface Crippler]

How many different/what type ballasts can I use to run these awesome bulbs? Can i convert a normal hps ballast to run them? Forgive my ignorance. Thanks

 

[TheChemist77]

ive been running the boulder lamp co, 315 lec lamp for almost 3 years now,, i love them!!! way better than hps,mh,or both... anyways its time to replace the bulbs,,they came w/ the phillips master elite agro.. but i went on amazon to order new bulbs and ipower, and other brands make the bulb at a lowe5r price,,the phillips is $90.00 and i can get the ipower bulb for $50.00
both show the same lumen output, kelivins, etc... is there a big difference?? should i buy the phillips or one of the cheaper bulbs?? do u think that the phillips bulb will grow plants any different than the cheaper bulbs???

• 
  

• Use a proprietary phosphor coating on the outside of the arc tube which can provide the richest spectrum on the market! Produces more PAR per watt than standard HPS Bulb
• 3100K color temperature. High 90 CRI. Optimal for flowering while also can be used for Veg as well
• 37,000 initial lumens, 120 Lm/W. 570 μmol/s. Promotes higher rate of metabolic activity and resin production through the use of UV far-red spectra
• High 90% lumen maintenance at 8,000 hr./High 85% PPF maintenance at 20,000 hr
• Great for indoor gardening or supplemental greenhouse lighting

please help,, i need to order new bulbs soon and dont want to have anyproblems or lower mky yields

Macular degeneration is age related, based on length of time the eyes are exposed to UV light.

Actually it has nothing to do with uv. It has to do with health and or genetics.

I worked as an account manager for Natural Opthalmics out of Colorado and they produced pharmaceutical quality vitamins and homeopathic to naturally cure eye disease.

Here is a good link to learn all about macular degeneration.

315 cmh runs only on low frequency ballasts.
