Hi all,
I thought I'd post two comparison photos showing the difference between the ADA Solar I metal halide with NA-Green bulb (150w, 8000K) and 2x TMC GroBeam 1500 Ultima (2x 30w, 6500K).

All camera settings are identical and the photos are straight from camera except for some re-sizing. I adjusted the white balance manually to achieve what I thought looked best - in this case 5200K for both set-ups.
Aperture - f/11
Shutter speed - 1/25 sec
ISO 800
White balance - 5200K
Both units were suspended 45cm above the water.
You can see the obvious difference in colour rendition.
What's also very interesting is the similar output in light - to the eye and PAR. PAR was 80 directly beneath the lighting in the centre of the tank, and 40 in the corners at the substrate - for both set-ups.
I'd be interested to hear which you prefer, and why?
Cheers,
George
