what type of lamp do you use?

[zoe4eva]

which lamp do you use? and why? is it the colour of coral growth?

[TerraC]

150w BLV 14k.. Used a Coralvue 14k last year. bought the BLV as i'd heard it gives off more of a blue crisper light than the coralvue but I cant tell the difference....

hearing more people using Marine Lux.. May give them a try next halide change...

[dan-the-man]

Have a 14k coralvue 400w. I'm happy with the look and growth. Am trying a 14k 400w BLV next time though. I will be switching lamps soon so I will let you know my thoughts on the BLV. :)

[instantsquid]

Tried BLV, CV and ML. Next lamp change I'm going back to BLV 10000K (I've added actinic T5s now)

[alanwsg]

Used to use a BLV 14K, just switched to MarineLux.
Much "blue-er" when first switched on but now I've got used to it and It prefer it.

[hihat]

I use 10,000k Marine Lux with Actinic supplement, gives a nice crisp light:cool:.

Used to use 14,000ks but switched to the 10,000ks to give better growth.

[nimmat]

have 2 x 70W 14000k BLV + 2 x T8 actinics. Planning to upgrade in the next few months to a 150W 10000k BLV + T5 actinics.

Marine Lux 10k, had them in 250w and now 400w, both supplemented with T8 Actinics and Aquablue+ T5's.

For looks, if you like a blue tint Marine Lux 14k are very nice, personally I prefer the much brighter 10k's though.

[reefkeeper_2006]

Running a Giessman 150w 14.5K

Nice crisp colour to it, much better than the old aqua medic 10K bulb i was using,
10K much to yellow for my liking

[Will]

Blv as they have been tested to give the most par along with geisman

[Will]

Tried BLV, CV and ML. Next lamp change I'm going back to BLV 10000K (I've added actinic T5s now)

remember to reduce your hours as the blv are around 30-35% more powerful per watt than the cv.

[Fastlight Distributors]

Hi Wills

I would be interested to know how you calculated this information ?

'blv are around 30-35% more powerful per watt than the cv'

you should give him some marine lux mate as it will get them going nuts for them in the states :thumbsup:

Why is the BLV and Giesemann plot exactly the same? Did Giesemann just re-badge a BLV lamp?

For the record, I use 400w BLV 14k because of their high PAR and long effective life, the lesser consideration is colour that we see, which is a nice crisp white with a hint of blue.

[davethefish]

giesemann 'coral' 14500K
as said, nice crisp and bright white.

i know they are very simialr but that doesnt mean they are re badged, but i cant comment as im not sure :thumbsup: the giesemann does out perform the blv on some of the ballasts so i guess they are not the same :thumbsup:

[daddio2003]

Just switched to Reeflux 400W 12K's. Or one anyway and other is Marinelux 400W 14K.

[dunc4000]

Fitted Arcadia 150W 14k when it came time to replace. Was AM 10k(13K? colour) I was getting much better growth before but was after a bluer look. Still undecided as to keeping the Arcadia, like the colour but need more growth.:scratchhead:

[blub]

Arcadia, although I dont actually have it running yet.

[iain360]

Xm 10k's 250w, supplimented by 2 x 39w D-D Pure actinic plus

[Something Fishy]

Geisemann 250w 14.5k 'Coral' as that's what came with my pendant ( Geisemann infinity). Advertising blurb also claims that they have a much longer service life than 'other' bulbs. Overall I'm very happy with colour, growth etc but am considering Marine Lux when it comes time to change as a lot of people seem very happy with them and they're half the cost.

[Screwloose]

does anyone know where to get the geisemann bulbs ?

currently running marine lux, and was considering changing to blv's to be honest,,,but always up for a change :D and i like the geisemann stuff

[ringo]

Twin 150MH BLV 14k for me

[chrisreefs]

I use 3 Arcadia t5s marine daylight blue and two T8 Actinics, with good coral growth

[Acropora]

Why is the giesmann lamps not included, in my view their coral lamp is the best.
