How to Make T5/LED Combo Look like Metal Halides

[oreo54]

* MIXING LIST
----------------------------------------
LED UV (390nm) [120°] x2
LED RoyalBlue (450nm) [120°] x11
LED Cyan (500nm) [120°] x7
LED Green (530nm) [120°] x2
LED Amber (580nm) [120°] x4
LED DeepRed (680nm) [120°] x4

Want a Radium look.. build that..
550nm spike is an issue like I mentioned but added a bit of green and amber
to compensate.
Lines are radiums, smear is a rough led construct.
all theoretical of course..
Maybe add a bit of regular blue as well to smooth out the dip in the led graph.

You're late...

BuildMyLED has been working on a combination of LEDs to replicate the look and ‘feel’ of a classic 20,000 Kelvin Metal Halide aquarium light for some time. We first heard of this marvel of spectrum reproduction over a year ago and through lots of trials, BuildMyLED is finally ready to let loose their exclusive 20,000K XB LED Striplight.

Built on the new BuildMyLED XB platform, The new 20K spectrum uses a plethora of different blue LED diodes, with emphasis placed on key wavelengths including the highly photoreactive 400 and 420nm spectrum peaks. Instead of using a load of 450, 460, or 470nm LED that most striplights are populated with today, the BuildMyLED 20K striplights definitely leans towards the violet colors which dominated the late 90s and early 2000s.

Not only does the lower wavelength blue light make colors pop like woah, it also lines up with the absorption peaks of zooxanthellae photosynthetic pigments. The video of the BuildMyLED XB LED striplight looks incredible, very colorful and although it seems a little on the purpley side to our modern eyes, this is indeed the look of a freshly fired up 400w radium metal halide lamp, sometimes backed up with some old school VHO Super Actinic fluorescent tubes.

Quick review of the BuildMyLED 20K LED striplight

I promised this a little while back, and so I finally banished the little ones to the TV and got down to it!I have been intrigued by the BML lights for some time now, basically since I saw one reviewed briefly with an overseas aquarium here on NR over a small ADA tank. I loved the small form fact...
