Cool white, specular light | |
| The unit emits a bright, cool white light. You can use a smaller heatsink if your heatsink has a fan. There is an R0 resistor to the immediate left of the LED chip that is missing by default. For the photographers in the group, the brightness from this light at 1 meter, ISO100, is about f2.0 1/60th. | ||

What is the perceived color of this light? | |
| I would like to use this in my home but don't want one of those magenta-colored emitters. What color output do you perceive with this grow light? | ||

Excellent Light Low Power Draw Lots Of Light | |
| Anyone who has grown indoors knows lighting is your primary expense, the solution many gardeners are moving to are LED fixtures, however compared to tube based lighting they can be expensive. If you are a gardener handy with tools and a bit of wiring knowledge this module gets you into LED lighting without breaking the bank. All that is required is the module, a heatsink MPJA part number 32088 HK, a power cord MJPA part number 34471 WI, a terminal strip MPJA part number 32940 TS and a ring terminal for grounding MPJA 20372 TM. Also if your greenhouse is warm at times, as many are, mounting a box fan to the heatsink is a good idea MPJA part number 3310FN. How well will this work, very well, side by side compared to a 250 watt metal halide lamp, using a older light meter I discovered this, 12 from the source, MH lamp 620 lumens, LED module 600 lumens, adding in the power factor of the MH fixture, thats a power reduction of 261 watts and that is more money in your pocket versus the power companies pocket and since LED runs cooler, summertime HVAC costs can be lowered a serious amount with LED lighting. So if you can DIY it, MPJA is the source and your bank is where you can keep the savings. | ||

MPJA Response | |
| Yes, you need to count the total surface area of the heat sink both sides of the fins. Example: Our stock # 32088 HK is 400 square inch at L:5-7/8 W:2-3/4 H:1-7/16 Thank You MPJA Inc | ||

Why ~600sq in for heat sink? | |
| 600 sq. in. is huge! All the other measurements are metric is it possible the we are talking about 600 cm^2 | ||
