125w eco lights vs 250w hps

i am debating weather to change from my 250w hps to 125w ecolight here http://www.growell.co.uk/p/1587/Eco-Lights-Compact-Fluorescent-Lamps-CFL-.html
what is the lumen difference. as i want to lower my electric bill but not lower my yeild. if they are equivilent in lumen i will buy one for veg and one for flowering.

Not even close to the same thing and would only save you 125w. What does that really cost you? 125w is the equivalent of leaving a regular incandescent lamp on.

You will decrease your yeild tremendously and not your electric bill.

I grew 4.5 oz's from 6 plants in 8 weeks (1 week veg, 7 weeks flower)start to finish with a 250w hps.

Done right, those little lights can produce.

would it be any good for veg as i have a 250w hps in my grow tent on 12/12 and in my wardrobe i have 4 18w cfl veging my little plants and i could do with more light for veg

Oh yeah, for veg it would be great. You might be better with a couple of 64w lights though, they only cost like $15USD at Home Depot (I don't know where you are) and they are 300w equivalent (just so you know which ones I'm talking about).

i read that you get roughly 65 lumens per watt in the 125w cfl so thats like 8000+ . i use one with and it seems to do the job pretty well only suitable for a small amount or 1 plant imho.. if i was you i would stick with HPS man..

i do still need one in my veg room as i only have 4 18watt cfls and i need more.

Man i got like 250w eco light vegging 70 plants. there growing well too. my eco lights have around 19000 lumens. plants need light in the correct spectrum, which is proven to be between 400 & 700 nana wave, and eco CFL's produce high output light in exactly this spectrum. There is no wasted light unlike discharge (Metal Halide & High Pressure Sodium) lamps where much of the light cannot be seen or used by the plant. Eco CFL's provide 100% P.A.R. (Photosynthetically Active Radiation) Eco CFL's do not generate excessive heat and can be used directly over plants. This is the secret of growing with them, positioned directly above, just 3 cm or 4 cm, the top of the plants. Eco is the future for veg, budding its not quite there yet. i still have a hps for that as well

Well, CFL's are NEVER going to be the next big thing. LED's are going to swoop in and STOMP them to bits. They are dirty (containing mercury), and DO produce plenty of heat. So to say that CFL's will get there for growing is a bit foolish. I'll bet they are stepped over in the next few years.

there is another fourm about LED. they sound wack.

There's a reason that these lamps don't have a lumen rating. If they did, you'd find they put out about 10% of the intensity of a CFL and about 0.25% of the intensity of a 400HPS (based on the very brightest LEDs made, the Philips Luxeon line, which make 140 lumens [and incidentally, the lamp you cite does NOT use Philips Luxeons] CFLs at about 1500 lumens and a 400HPS at 55,000 lumens).

Remember that lumens from multiple light sources don't 'add.' A pair of 140 lumen LEDs lighting the same area will apply 140 lumens to the area, not 280. Same goes for any multiple light sources. Putting dim lights next to dim lights does not give you brighter light- it gives you more sources of dim light over a certain area. If this multiple LED lamp used Luxeons, its luminous output would still not exceed the lumen rating of a single Luxeon LED.

The short answer is 'yes- too good to be true.' LEDs are very expensive toys- and you won't grow any dope with them. Anyone who thinks they will grow dope is a fool. You'd be better off trying to grow with candlelight- at least you'd get some CO2...

I'm rarely this unequivocal on matters asked of me, but I'm a bit sick of both the idiots selling this garbage and the nongs on cannabis boards trying to convince others that they actually will work in the manner advertised. They don't.

LEDs have a future in lighting- whether that will include lights which can grow cannabis at some time in the distant future or not remains to be seen, but the simple fact is that right now, there's no such thing as an LED light that will grow cannabis successfully. Anyone taking your money for such items is a thief, plain and simple. Consider yourself warned. If you buy LEDs to grow dope, you'll get some interesting looking lights but no dope.

If you want to grow buds, select the most powerful single HPS you can use in your space and still control temps below 26C. Cooltubes make this deadset easy.

Wow, I don't usually disagree with Al B. Funct, but it's not new science that light IS additive. I'm not going to debate whether or not LED's are viable now, but I'm certain they will be the lights of the future.

The statement here that makes this entire blurb fail is that light isn't additive. Take a flash light and point it at the wall. Now grab another flashlight and point it at the same point......circle got brighter. Simple.

Why don't they use one big as light on top of a baseball stadium?

Why have flourescent light fixtures in buildings with 3 or 4 lamps? Ever wanted it to not be so bright so you twist one of the bulbs out?

It's just a retarded statement plain and simple. Where did you find that?
