L8 2 RISE Posted June 10, 2011 Share Posted June 10, 2011 I just put the light up and used the par meter on a tripod to get the following readings. Each one was the highest value I could get to stay steady at each level: Right next to the light (up to 3 inches)- Off the scale, over 2,000 1ft-750 2ft-242 3ft-111 4ft-64 I'll keep the set up the way it is for a little while if anyone wants me to check anything else. For the review thread, see here: http://www.nano-reef.com/forums/index.php?...+dimmable+par38 I don't know what to make of these values, so if someone with more experience with LED's wants to chime in and interpret, please do!

psidriven Posted June 10, 2011 Share Posted June 10, 2011 Can you take readings for distance underwater? Par drops real fast in water. Just do the same thing but for 3-6 inches under water instead of feet of air. Link to comment

That's about expected for a lamp with such tight optics. What will be more telling is to set a distance up, say at 2ft, and start measuring off axis every 2". Link to comment
L8 2 RISE Posted June 10, 2011 Author Share Posted June 10, 2011 Ask and you shall recieve. I didn't till the par meter at all as I did this, I just moved it away from the light pointed straight up. If I tilted it I would get slightly higher results. At 2ft- 0in=242 2in=213 4in=88 6in=33 8in=18 10in=10 The water one will be a little harder, but I'll try later. Link to comment

Right there shows you how tight they are. This shows very limited area coverage, depending on how much light you want on the sand. Link to comment
MGDMIRAGE Posted July 11, 2011 Share Posted July 11, 2011 Yeah i have 4 of these lights, but the 30 degree optics are rough hehe. Link to comment
