Mega-Ray 100w Measurements
Changed the 100w PowerSun and installed the Mega-Ray 100w on Monday Dec 9, 2013 @ 1500.
Initial reading is 200 µW/cm2 at 9” from the bulb surface, within minutes of turning on the lamp.
The bulb face is 13” from the basking log surface. The estimated reading is 100 µW/cm2 at the surface of the log when taking the reading from an angle. At about 3” off center angled at the bulb the reading was 80 µW/cm2. These readings are well above the readings of the PowerSun 100w MVB when installed initially.
Temps and UVB readings at 30 minutes of burn-in;
Basking log surface temp: 87.6 degrees Fahrenheit
UVB reading @ 11”: 115 µW/cm2
LUX @ 12”: 7,600 LUX
When the lamp was first turned on it gave off a yellow hue. After a couple minutes the yellow hue began to turn more bluish. At 30 minutes of burn-in the color is a bluish-yellow tint. I like it better than the PowerSun’s orange tint. It looks more natural to the naked eye.
3.5 hours of use;
Temp on basking log 90.7 degrees Fahrenheit
UVB @ 11”: 110 µW/cm2
LUX @12”: 5,100 LUX
The UVB reading is right about where Toku’s limbs will be I like how the bulb doesn’t give off a ton of heat. 90 degrees is better than 100 degrees in my opinion. I the short time the bulb was on today I was very happy. The bulb was on from 3:00 to 7:00pm today. Tomorrow it will come on at 7:00am (normal time) then turn off at 7:00pm. As you can see, I run my MVB 12 hours a day and the day lights from 9:00am to 5:00pm. One thing to point out is the LUX reading dropped because the last reading at 6:30 tonight was with the day lights off. The color tint from the bulb is a bluish green color and a hint of yellow being visible.
I have a couple pics of the Mega-Ray without the day lights on;
And for comparison the PowerSun 100w;
I hope this helps anyone considering to make the change to the Mega-Ray bulbs. I will get a pic with the Day lights on sometime in the near future.
