Philips 315w CDM Elite (CMH)

[willowz]

No idea as to whether they are good or bad, Krunch.

Just from the numbers and the write-up, they sound like a Chinese knock-off to me. There have been numerous offshore copies of the Philips lamps, but as far as I know, they haven't worked out well. The ability to use ballasts that aren't low frequency is a new development - supposedly the 315's will rattle apart at high frequencies. They might be great, but.....

In addition to that...

If that spectrum posted is actually bona fide, then I would expect Philips to follow up with some bulbs of that sort, and maybe some companies will offer retrofitted DE fixtures for such CMH lamps. I'd expect DE CMH lamps would be more longer lasting at the lower frequencies of the CMH ballasts than MH and HPS bulbs. Just wondering.

I haven't studied the DE systems so I don't understand the output characteristics of the ballast.

It's an interesting approach because it takes half as many ballasts. If legit, it could bring down the up front price per watt significantly.

it is two arc tubes inside one outer envelope,

Greenbeams designs a reflector to minimize light reflecting back onto the lamps arc tube, and these guys mount two arc tubes right next to each other, seems to be some difference in the thought process there.

They do not appear to be "protected", just the single outer glass envelope

There is a good reason Philips and GE will only operate ceramic metal halide lamps with LFSW ballasts

If they do intend you to operate this lamp with a high frequency ballast, please use an enclosed reflector.

I think the greatest disabling factor for fast adoption of these bulbs will be their safety record or at least a factor I hope people consider... It could be that Philips decided not to use these for that sake...

About to pull the plug on 3 global units. Anyone have any comments about the company or product?

Looks like there's 2 glass jackets on these growlite bulbs. Really weird design. look how big that otter jacket is. I dont think this is the same as the Growers Choice?. These still use LFSW ballast.

So would you guys say this bulb is bad or?

I have to replace 4k in DE lamps for the summer and it will be these bulbs or LED's...

LED's will just cost too much for me, so these sound really good to my wallet...

was just getting a quote for new 630s, but hell now im going to wait.

are they saying these GC DE 630s bulbs will work in a Nanolux DE fixture

 

[Hammerhead]

those DE fixtures use 2 Separate 315w bulbs and they dont have the right ends to use DE bulbs.

on which Hammer? i have the nanolux DE1000 right now

This thread is for CDM/CMH/LEC 315w bulbs and fixtures. Any 630w is a DE OR 2 SOCKETS. CDM 630 fixture use 2 315w bulbs with 2 pgzx-18 Sockets in them. So no way to use a DE bulb in any of these. New fixtures or fixtures that have the DE bulb sockets would be needed to use these new bulbs. 315w CMH bulbs you will need to use LFSWB to fire them. That Growers Choice DE 630 Bulb is a 1st for CMH might not be safe for open fixture use. No one is sure how to fire them yet. Sending 1000w to a 630 bulb is not safe.

the de 315w cmh from growlite doesn't offer an increase in PPF, it actually offers less. I haven't got any numbers unfortunately but that is from growlite themselves when I sent them a message after I saw a post of theirs online.

Now that cmh and de are "proven" technologies for growing cannabis, every charlatan and shit-heel with an angle will be trying to cash in on the "new thing". Due diligence before spending hard earned cash is a must.

The phantom hood showed up last night, so I should get some testing done later today. I'll post up the results and greenbeams comparisons ASAP

that growers choice lamp is the one im referring to, these Nanolux ballasts are dimmable as well so wouldnt have to send the full 1000 watts

 

[Hammerhead]

using any ballast with more power then what the bulbs are rated for is not recommended. I dont think we know if those new 630 DE bulbs can be fired on a digital HF ballast. All of the CMH bulbs we use have to be fired on a LFSW ballast.. I would need more info before using 1.

Looks like the Phantom reflectors are back in stock.

 

[krunchbubble]

Couldn't do anything able the sockets for the aircooled LEC as they are already in production...

I couldn't even remember all the numbers when I was asking em...

I bought 3 retrofit kits from growers house.
The shipment of prism ballasts was pushed back so I upgraded to phantom ballasts rather than wait an extra month.
They are very bright and the heat they push out is minimal.
Going to order more to replace all my 600w's when they restock.
Can't beat their prices.

The outer glass on the bulb is for uvb protection according to what I read on the box.
It says not to use it if the outer glass is not in tact

All metal halide lamps carry that warning. A single layer of glass is sufficient for the purpose. 315 T12 lamps have two layers to contain flying debris in the event of very rare catastrophic emitter failure.

The UV is clearly contained by the INNER tube...don't try this at home:
