Hi Everyone.

I have just stumbled onto an 'energy saver' lamp with interesting possibilities at a local electrical wholesaler, immediately bought myself one to play around with, and thought I would pass on the information for everyone's benefit.

The lamp is a 85W Eurolux G384BP 'energy saver' power compact fluorescent with a built-in ballast and E27 base. It is in essence just a larger version of the common household energy savers, measuring approximately 300mm in length, and 90mm in diameter. According to the information on the box, it emits the equivalent of 425W of incandescent lamps - that is 5100 lumens, or approximately half the intensity of a 150W metal halide. The color is only described as 'daylight', and I suspect it is in the order of 6000K.

Although it is bright enough to illuminate a 600mm x 300mm nano tank quite nicely (I think it would be bright enough for even SPS in this size tanks) I think it could be really useful in illuminating a sump (where the 6000K color won't bother anyone...).

The really nice thing about this lamp is it's cost - R130.41 for the bulb, and R203.00 for the luminair (lamp holder), complete with cover glass.

Here are some photos:

hmmmm Hennie, seems like we've got the same ideas! LOL :) Replaced one of the T8's in my setup with 4x 225W energy saver equivalent :) Works PERFECTLY. Below is a pic of the mod - tho it's only with 3 of those bulbs... now have 4 running. :) :thumbup::thumbup::thumbup:

A Beautiful place!
Let me know if you (or anyone else...) battle to source this lamp, and I will gladly buy it from my local supplier and send on to you.

That's kind of you Hennie, do you cover the costs as well?:whistling: :whistling: :whistling:

AWESOME - many thanks for sharing this with us, Hennie! BTW: do you own a light-meter? How much PAR does this light measure at different distances?

You say that it has half the lumens of a 150 watt metal halide? How do this energy saver compare to say, eg. T5's? 150 watt metal halides? Do you have sample/example lumens outputs perhaps for each?

Many thanks.

No, I don't have a PAR meter - wish I had, though...

From the box the lamp came in: 85W Daylight: 5100 lumens
From my Philips OEM catalog: 150W MHN-TD: 12900 lumens
From the same catalog:
'standard' 15W CFL 'energy saver': 900 lumens (equivalent of a 75W globe)
24W T5 fluorescent tube: 2000 lumens
54W T5 fluorescent tube: 5000 lumens

So, it's about the same lumens as a 55W T5, but in a 'point source' of about 170mm length (the glass part of the lamp).

As I said earlier, the main advantage is price - that R130.41 I paid INCLUDED the built-in ballast (and VAT).

If you were to buy a PAR meter, which one would you recommend? Not a top of the range one, just one that is simple, reliable and does the job required.

Buy a good one we can all share yours.

Well, my thoughts are this, pending approval of the other admins and also depending on the price...I was thinking maybe MASA could contribute a portion of the cost towards the purchase of a PAR meter for our community. It is something that we are lacking in this country.

Daylight MH bulbs ain't that expensive? Yes you have the ballast as a once off, but then you get the more lumens and deeper penetration, not to mention the glitter lines, and you use less electricity or similar amounts. (85 x 2 = 170w + overhead) Great for a nano though, where you do not require that much light and if you have heat problems :p

Hennie, now convince them to make those in 10 000k :p

Any idea what sort of brightness the 80W T5 is ?
