Tolifo PT-15B Product Review

One of the things I've been wanting to do is to get some better quality lights for making videos that I post to YouTube. I reached out to Tolifo, a company who makes budget LED video lights, and they gave me some discount coupons in order for me to be able to purchase some lights for review. One of them is the PT-15B. That said, here's my review.

The packaging is nice, and the product is fairly well-protected. The first thing I noticed when I opened the box is the metal housing of the light. It's thin, but has a little bit of heft to it owing to the fact that the housing acts as a heatsink for the LEDs.

The one thing that I was torn on was the fact that the diffuser is built into the housing, and is not removable. I wondered about it, until I first fired up the light. This thing is BRIGHT. It's rated at 15 watts, with an output of 1500 lumens.  When I make my YouTube product review videos, I use DIY fixtures I put together with a 16.5 watt 5500k bulb that is rated the same. I use a diffuser made of an opaque shower curtain, which does a really good job, surprisingly. This is much less diffuse, and is much more directional. More on that in a minute.

I used NP-F750 batteries that I bought specifically to use on lights like this, as they are all standardized on this Sony format. I can purchase just about any LED light out there, and will have batteries for them, as almost none of the lower-priced units come with either batteries, or AC adapters.

I found that this light is much less diffuse than my DIY solution, but that's not necessarily a bad thing. I tested it by placing it at the same distance from a photography subject (a Lego truck), and it seems much brighter, but that's because of the proximity. If I were to pull the light back to where it was more spread out, the intensity would be comparable to the DIY light. I didn't test that specifically, as I was trying to do an apples-to-apples comparison - which ultimately failed. Here's why:

The DIY fixture is built using a plain old clamp shop light (silver reflector) with a 100 watt equivalent LED light bulb in it, with the opaque shower curtain diffusion material over the opening to the light, connected to a light dimmer switch. Here's the issue - the bulb itself is already diffused, so by adding the shower curtain, I'm getting double the diffusion, so the comparison to the Tolifo light isn't really fair.

The light is about $29 on Amazon (plus about $12 for the battery), and by comparison, my DIY lights cost roughly $16 ($9 for the clamp,$3 for the bulb, $1 worth of shower curtain, $1 extension cord, $1 dimmer, $1 electrical box)

$41 - Tolifo solution
$16 per light - DIY solution (I have three)

All that said, I'm going to have to do some real-world testing to really evaluate the light, but so far, it looks like it has found a home in my YouTube-making parts list.


The basic (paraphrased) information Amazon provides on the product is below:

• FUNCTION: The CRI95 provides you with a professional quality compact LED light panel with a high definition LCD display – perfect for your DSLR, camcorder or tripod and an excellent addition to any photography studio lighting kit
• FEATURES: Smart LCD display panel, warm to cold color temperature adjustable LED (3,200 – 5,600k) bulb for outstanding reproduction of color, dual power design, and hot shoe adapter camera light mount
• DESIGN: Light panel is made with a super lightweight aluminum alloy housing, with a portable pocket-sized frame, a dual power supply (DC input adapter or battery powered) and built-in diffusion panel to ensure efficient light transmission
• EASY TO USE: Controls include a power button, long press color temperature setting mode (for indoor or outdoor), and 2 buttons that manage the brightness (from 10-99%)
• COMPATIBILITY: Supports applicable battery NP-F550/ NP-F750/ NP-F970 series or DC input adapter 13-17V (Note: battery and ac adapter ARE NOT included)

Keto Weight Loss Update - Week 21

Week 21 results are in, and I lost weight again this past week, but after reading the numbers, I was a little confused.

I didn't do any exercise this week, and while I lost 1 lb, I gained body fat. This could be due to the body fat analysis scale picking up food in my digestive system. I'm not really sure about that, but have noticed some fluctuations in the reading that seem to depend on what I've been eating. I'm eating a lot more veggies than I was, and less protein, so that could have an effect, as the system uses electrical resistance to measure lean mass, so it would figure that if there's a large amount of protein in your system, that the scale might see that as lean mass.

Anyway, the numbers show that my body fat percentage went up by 1%, while my weight dropped to 178.5 lbs.

As I mentioned, I'm eating a lot more vegetables, and less protein. I'm going to get back to exercising again, hopefully, so we'll see what happens with that.

Keto Weight Loss Update - Week 20

Week 20 results are in, and I was super-excited when I stepped up on the scale! I came in with the lowest weight so far, and finally (after my holiday plateau) broke the 180 lb barrier!

I haven't been exercising much at all, but last Sunday spent the entire day doing the move of the garden bed. I started it a couple of weeks ago, but didn't get any of the dirt moved due to a change in the weather. I worked my butt off, literally. I dug and dug and dug, manually moving every wheelbarrow-load, and finally gave up and rented a tiller. It turned out that the trees that were the root cause (pun intended) of me having to move the bed in the first place had sent out roots up into the bed, and made it very difficult to do by hand. Even the tiller had trouble with some of the roots.

Anyway, the numbers show that my body fat percentage dropped like a rock down 26%! My weight, as I mentioned above dropped to 179.5 lbs. That said, based on the calculation, I lost 4.01 lbs of pure body fat last week! Amazing! I hope to continue that downward trend, especially with spring coming, and yard and garden work starting soon.

I altered my diet a bit to lower the amount protein, increasing the vegetables and fats.  I am still doing 2 tablespoons of MCT oil in my coffee with 2 tablespoons of heavy cream and will stick with that for a while.

Keto Weight Loss Update - Week 19

Week 19 results are in, and I totally missed entering the last two weeks, so I've inserted those.  I worked out a couple of times during Week 17, and did some heavy yard and garden work in preparation for spring planting, so that counts as exercise in my book.  It included building a new raised bed, digging and moving dirt and compost, etc.  It was actually pretty physical.  My weight has continued to come down, and body fat has dropped too, yay!

The numbers show that my body fat percentage went back down to 28%, which is back down to the lowest it's been so far.  I hope to continue that downward trend, especially with spring coming, and yard and garden work starting soon.

I just have to keep on doing what I'm doing, I guess. My diet has been heavier on the protein than is probably good, so I'm going to back off on that a bit, and just eat more vegetables and fats.  I am still not using the combination of butter, coconut oil, and heavy cream in my morning coffee.  I removed the butter and then the heavy cream, but have since added 2 tablespoons of MCT oil back in.  I started that back in Week 17.
