Fulham questions

[Delphinus]

Just looking at all the different Workhorse models .... I'm a little confused here. What's the difference between a WH2 and a WH22; a WH3 and a WH33; and, a WH7 and a WH8?

[Tau2301]

Looks like the diff is the maximum rated current.

[Bob I]

That's all I can spot. The 22 has .8 amp lower maximum current than the WH2. Similar differences between the 3 an 33. You would have to print out the spec sheets, and look at them side by side to be really sure.

[Delphinus]

Isn't "Watts" (or more rather "power") just current, times voltage? Or some such. So if volts are 110, or 120, or whatever it is out the wall, and one is rated X current draw, and one is Y current draw, and X > Y, then how can the two ballasts have the same wattage rating? Like for the WH7 and the WH8, they can't both be 220W, one must be more like 215W and one more like 218W.

Or am I completely out in left field here?

...

Oh, on a point of interest, I got this email from Fulham today regarding the availability of ballasts for 175W metal halide, and ballasts for 250W metal halide ("HighHorse" model line ballasts):

From: "INFO AT FULHAM" < INFO@fulham.com >
To: "Tony Slotboom" < entacmea@hotmail.com >
Subject: RE: Availability of HighHorse ballasts (175W/250W MH)


Tony - these are not yet available. I believe we will have an offering
sometime this summer.

Thanks!

I wait with baited breath... summer seems so long away .... oh well.

That would be awsome.
Hey Tony, I assume that you know that BRITE LITE in calgary carries the horsey ballast's that are the topic of this post?

[Delphinus]

Haven't bought any from them, but had noticed that a BriteLite over in Ontatio is listed on the Fulham site as one of their distributors, and I figured if one franchise has it then likely possible another one would too?

I've bought other goodies from BriteLite in the past ... when I had more reliance on fluorescents I got my 7500K NO tubes from them. Nice bulbs actually, always wondered how they'd do overdriven (they're T15's though ... the fat fluorescents, not the thin ones).

Yea Kim was in there and he told me they stock the workhorse ballast's.
on and super cheep daylight compact flourescents.

The short answer is yes. It looks like you are comparing apples and oranges. I want to try and explain, but when I try, I confuse myself. Maybe our engineer friends will jump in with the formulas.

Did Kim say in what wattages? I use both 13W, and 32W CF lamps on my new 20G high Mini Reef. That comes to 90W of Power compact fluorescent light. Using the NO fluorescent formula that comes to 4.5 WPG. But factoring in the fact that CF's have twice the lumens per watt, we really have close to 10WPG. IOW, it is nice and bright.

[Tau2301]

55 watt, 6400K, straight pin(4) for $16.00, sockets $3.00 ea.

also a 13w 6400K, I think the price was about $7.00

They stock the Workhorse 5&7, $45 & $60 respectively

Terry, the person I always deal with, is willing to bring in special lamps, but you usually have to buy a case - what ever a case is for that item, the Qty varies.

Might be an idea for another group purchase.

I was think of taking out two of my 2x OD NOs and replacing them with 4 - 55 watt bulbs.
