I was surfing the net for deals, and I stumbled upon this-

MaxLite SKO200EA50 (35871) 120 Volt 5000K HighMax High Wattage CFL Bulbs - Fluorescent Lighting Retrofit 200 Watt Compact Fluorescent Bulbs at greenelectricalsupply.com

It's a 200w CFL, equivelent to a 400w MH bulb. Sure, it's expensive... but I'd still love to try one someday.

oooo nice. *drools* thats some good lumen output :-)

That is a very good find and the lamps for $78 is also a good deal. By-passing the ballast is a piece of cake.

Did anyone read the fine print for the bulb:

Note: Do not use with dimmers, timers, photocontrols or other special switching devices.

That sucks for us growers, no timers. BOOOOO!

This looks to good to be true

does anyone know what scotopic lumen are? I have hear the word in relation to vision problems and learning disabilities but never as a modifier for lumens

why not use with timers?

Htg has t5 lights at 80$ with ballast that use 110watts and produce 10 thousand lumens
Super producer. And u don't have to buy anything else
Replacement bulbs. 2 for $17

I'm not really sure why you wouldn't be able to use a timer, might have something to do with the ballast they have built into the base. I'm sure that at any rate you will void the warranty if you have any problems while using a timer.

I dont see why you couldn't use a timer.. it's turning the light on and off..

yea that question is throwing me for a little loop too. does any one know why that is....

I had the same question and even contacted the supplier but they never replied. They may be referring to digital timers? My cfl's have the same warning on the box and been using a mechanical timer since 1/1/09 and no problems.

well most timers used in grows are simple clocks with a relay switch to them, so they either connect or disconnect - otherwise you could run a HID with them either. i guess this might go for some digital timers turn down the voltage like a dimmer, that could send them into cycling but besides that it might just be a good intended but useless advise as "don't microwave pets"...

Hope that helps !

Looks very similar what i am using. I have had no problems

200W ENVIROLITE CFL Grow Lamp / Light - 2700K Flower on eBay, also Hydroponics, Plants Seeds Bulbs, Garden Plants, Home Garden (end time 29-Apr-09 17:34:30 BST)

Can I use my compact fluorescent on an electronic timer?
Some electric timers have a small amount of electricity running through the product even when the lamp is off. This makes the lamp continually try to start itself, which causes the CFL to have a short life.

thank you Richard that is very helpful....I was confused about the term and thought it might be a gimick to make the product seem better than it was...it must be a term helpful for designers and architects trying to create the desired ambience for a space. So if I understand the info correctly we know the light is better for veg like a MH rather than flower like a HPS...and that it is a good reading light lol

It also means the actual lumens for a comparitive basis may be half as much as the manufacturer claims....assuming that most specs use phototopic lumenss

what do you think, am I following correctly?

Iam using two of the 300w replacement uses 65w.. They work great.here is the link.

aren't they self ballasting? I use similar but with lower lumen output and it has its ballast built in. those ones have fantastic output though. always used with a timer and didn't have any problems.
