Economical Green Line Laser Module 520 nm, Class 1, 7~10 VDC, >60° Fan Angle, 0.3~1.8m Working Distance, VLM-520-28 LPT - Industrial Alignment Laser for Automation & Machine Vision

Bought to replace laser guide on Ryobi sliding mitre saw as unable to get exact replacement. Slightly longer than original laser but same diameter. Fitted OK with only a small change to holder and works a treat.

Poor

The item arrived in time but it's completely damaged.

the units do not last long and the supplier never answers question or contacts. would not use

works as described

丸ノコのガイドに使用したのですがとても明るくて狙い通りでした。

店舗改装のため図面がない現状天井を撮影して図面化する為の撮影範囲を判るよう天井に照射しています。赤色レーザーは明るい所では分かりにくく、18650の3.7Vのリチウムイオン電池をDEC-DCコンバーターで9Vに昇圧して使っています。12Vまで使えるようですが、明るさあまり変わらず電流値は上がるので、熱に変わっているようです。耐久性に関してはまだ分かりません。

rispetto a prodotti di minore prezzo la linea laser risulta meno definita (a distanza di 20cm si vede non una riga ma una "ellisse" con asse minore di 5mm), in oltre anche alimentato a 5v la riga risulta meno visibile di altro prodotto più economico.

This thing is tiny. I’m talking smol compared to other lasers I’ve purchased. Bought this specifically for the higher voltage range forgetting that my power supply changed to 5.5vdc. Still works but seems to pick up full brightness at about 6.5v right under its rated 7v minimum and stays consistent to the top end of voltage range. Idk what you would use this for but seems like better quality than most so far. I’m just going to mount it to the hood of my RC car so I can make trajectory adjustments better doing speed runs at night lol. Plenty bright for my needs. Haven’t tested in daylight yet but green usually picks up better and this wasn’t sold as a daytime laser.
